Carry the world's first titanium retractable permanent marker every day to make a bold statement on surfaces that a pen can't write on.

Latest Updates from Our Project:

Is MARKSMITH also the World's First Titanium Highlighter?
over 1 year ago – Thu, Nov 12, 2020 at 11:34:58 PM

I received a lot of questions as to whether the MARKSMITH FINE would be compatible with highlighter cartridges. Watch the video below to see the results.

I'll be doing a GIVEAWAY for a MARKSMITH production sample with a set of 5 highlighter cartridges (to be shipped with your Marksmith). All you have to do is LEAVE A COMMENT ON YOUTUBE VIDEO (About whether you would like to see the highlighters available as an add on (or don't care), and if you prefer a specific color, or want the set of 5 different colors) and BE A YouTube SUBSCRIBER (Link To SUBSCRIBE to my YouTube Channel if you haven't already). One comment will be chosen as the winner.

I'll be reading your comments because I want to know the level of interest in the highlighter option to get an idea of how many highlighter cartridges I should prepare.

Production Update

Production is moving along. The machine shop says that they are 2-3 weeks from shipping.

The MARKSMITH ULTRA-FINE production samples have also been completed and will arrive soon. I've already gone through the prototype process with those and planned to launch a Kickstarter for them sooner, but based on the time that it has taken to get the MARKSMITH FINE production completed, I decided that it would be best to wait until the kinks have been worked out of the production samples.

Thank you,

Logo or Lack Thereof
over 1 year ago – Fri, Oct 30, 2020 at 11:35:22 PM

The overwhelming feedback from everyone has been "no logo", so that's what I'm planning to do. I've heard from many backers that the minimalist and clean appearance is what made them pledge for the Marksmith, so I won't be changing that. Therefore, there will be no logo on the marker body for all Kickstarter backed Marksmiths. Watch this video where I discuss some of my thoughts on a logo for post-Kickstarter Marksmiths, and also the packaging design. I'd like to hear your feedback on those ideas.

I do want to investigate logo designs and locations for the future (post Kickstarter). There have been some interesting location suggestions: 

1. On top of the rounded end

2. The underside of the clip

3. On the slide that the clip is attached to (it is hidden until you extend and rotate the bolt)

4. Next to the threads on the tip, such that you have to unscrew the tip to reveal the logo and a serial #

I plan to add a design to the metal box, and ultimately a cardstock sleeve that slides over the box (this is likely going to be for post Kickstarter units). Are you a graphic designer that could help with the logo design, or a packaging designer who could work on the layout of the cardstock sleeve design? I would love to have the Kickstarter community contribute to these design elements.

MARKSMITH is the name of the titanium marker. SOUL BUILT is the brand that I have recently created that will encompass the EDC gear and KRVR kitchen knives that we make. (If you haven't seen my knives: and )

For me, there's a lot of meaning behind the brand Soul Built. It truly describes what we do to take these designs from ideas to real products in your hands. I will delve deeper into the meaning later.

Production Update

It took longer than expected to review details and discuss production with the machine shop after the second sample set. The production downpayment (which covers the first half of the Kickstarter orders) has been paid, enough material and tooling for 5,000 Marksmiths was ordered. The first batch of 500 Marksmiths is currently about 30 days out. I was told that the next batches will take less time than the first because the material and tooling will be ready to go.

NOTE: Bastion Ti Pen

Bastion will be announcing their new Ti pen on an update to their prior Kickstarter campaigns that I managed.  Their pen should not be confused with the MARKSMITH line of titanium writing instruments produced by me. I was involved with the original Bastion Carbon Fiber Pen Kickstarter, but their new ti pen was developed independently of me. I just wanted to clear up the distinction in case there is any confusion since I've also been saying that I plan to make a titanium pen. That being said, their new ti pen is the same design as the previous stainless/cf pen which is a great pen that many people love, and therefore I would not hesitate to buy one. It has an independent bolt and clip design. In contrast, my pen design follows the Marksmith aesthetic with an integral clip and bolt, where the clip is used to extend and retract the pen.

2nd Production Samples Arrived, and this is what I found
over 1 year ago – Sat, Oct 03, 2020 at 08:46:52 PM

The MARKSMITH 2nd Production Samples arrived yesterday, and I immediately unboxed and thoroughly examined them in this YouTube video. Check it out!

I'll be doing a GIVEAWAY of 2 of these 2nd Production Samples (to be shipped with your Marksmith). All you have to do is LEAVE A COMMENT ON YOUTUBE VIDEO (about a future piece of Titanium Gear that I should make) and BE A YouTube SUBSCRIBER  (Link To SUBSCRIBE to my YouTube Channel if you haven't already). I will choose the BEST and WORST idea for the winners on October 15th (Please LIKE or DISLIKE ideas to help me choose).

2nd Production Samples Overview

They work and look great. The functional issues from the previous samples were resolved.

There are 3 minor things that I am requesting that they fix for production that I discuss in the above video.


I've requested that they start on a first production run of 500 units. (Originally I wanted to start with 100 pcs, but we are running behind schedule, so I'm increasing the qty) We need over 3,000 pcs to fulfill all Kickstarter orders, and I know that you are all eager to receive yours, but it's better to do smaller batches to ensure the best quality. 

Thank you,

Production Samples #2 Have Shipped
over 1 year ago – Thu, Oct 01, 2020 at 09:30:13 AM

A few backers have been asking for more regular updates. I'm the "save it up and pack a lot of info into one update" kind of person. I will try to be the "spread it out into more regular updates" kind of person for you all. Therefore I'll save some (non-critical) info for another update.

Production Status

The machine shop has confirmed that the 2nd Production Samples have been shipped, so I am now waiting to receive those. I spoke with them on a regular basis during the machining, going over details and changes to make sure that everything is perfect.

Watch this YouTube video for more details about the 2nd production samples. The images and videos are from the machine shop. I do not yet have them in hand. Once I do, I will take more pictures and video of them to share with you.

Don't forget to SUBSCRIBE to our YouTube Channel, where I publish videos about the MARKSMITH, future Ti EDC products, and other things we make at Engineerable, like the KRVR Chef Knives.


Packaging design and sustainability always weigh heavily on my mind when making a product. I generally try to keep the packaging to a minimum and make it either reusable or recyclable. For the Marksmith I'm choosing a metal box with a foam insert, so it will be both reusable and recyclable.
      If you are giving the MARKSMITH as a gift, it is a nice gift box
      If you want to keep it to store your MARKSMITH, you can do so and it won't degrade.
      If you want to recycle it, the metal can be recycled with steel products (food cans), and use the foam as extra padding next time you ship something.


There were a lot of comments about the large logo on the clip that I posted in the prior update. That image was actually a mistake. I forgot to change out the image before publishing the update. I was trying out different logos on the clips, and I posted the wrong image.
      However, it seems that the consensus is it would still be too large, and many of you expressed that you liked the design on the Kickstarter with a clean clip. Looking at it more, I tend to agree. I spent a lot of time on the clip design and slapping some writing on it really throws off the aesthetic.
      So, I'm going to keep the clip clean and free of text. I will still be putting a small logo on the side of the body, at 90 degrees or 180 degrees of the clip in the closed position. Something more discrete.
      I won't let the logo hold up shipping. If it is going to add time, I will ship without it. I will talk more about the logo in a future update.

      Thank you,

Production Update - Production Samples Reviewed
almost 2 years ago – Wed, Aug 26, 2020 at 05:53:32 PM

Grab a coffee or a cold one, and sit back in a comfy chair or hammock, because this is going to be a long and detail-rich update!

Production Update

The production samples arrived! There were some delays with the samples due to broken drill bits. A broken drill bit holding up production? That may seem trivial, but the drill bits used to remove the material from inside the marker body are specialty bits that you don't just have on hand. They are a specific diameter, carbide, extra-long with thru-coolant holes for keeping the titanium as cool as possible during the deep hole drill. Some of these bits cost over $500 and have replaceable inserts. Not something you want to break on a regular basis. Once the machining parameters are tuned in for production, things go much smoother.

Yes, that is a black titanium Marksmith next to the natural Ti Marksmith. It's beautiful. Unfortunately, I'm not going to make these yet, because I need to do some long term durability testing of the black coating. 

Marksmith Ti next to a prototype of the Marksmith Ti Black

I had the samples made in 3 different finishes to compare them. The brushed finish like what was shown in the Kickstarter. A bead blasted finish, which is more matte, but unfortunately scratches too easily and can't be refinished by hand with a scotch-brite pad like the brushed finish. And a black finish which is supposed to be the most durable black finish available for Ti.

Left to Right: Bead Blasted Ti (Scratches too easily), Brushed Ti (the original finish), and Black Ti (durability to be determined)

Did the Production Samples Pass the Test?

Yes and No. The samples were good, but a few things have to be tweaked and we're gonna need another sample run before production.

The Good:

The exterior machining of the clip is perfect, exactly like I wanted it. I am thoroughly impressed by every single machining detail of the clip because it is the most geometry complex part of the Marksmith.

The screws were changed from flatheads to low profile Torx socket cap screws. This change makes the height of the screw in the counterbored hole more consistent so that the screws are always flush with the surface. Flathead screws are much more difficult to always make flush with the surface, especially since small dimensional changes in the screw head between batches can cause the screws to be too high or too low, even if the machining of the part they fit into is consistent. I experience that with my kitchen knife handle making, where the flathead black, silver, and gold screws that I purchase all have slightly different head diameters, which cause the screws to be at different heights even though we CNC machine the countersinks.

The external dimensions and most internal dimensions are perfect.

The brushed surface finish looks amazing and is easy to keep looking like that.

An o-ring was added to the screw connection between the tip and the body. This keeps the tip on tight and prevents it from loosening. 

O-ring keeps everything tight!

The Things that Need to be Fixed Before Production

1. The main issue was that the internal features were about 1mm too short to properly extend the cartridge. Let me step back a minute and explain how this happened. The prototypes were made by us in our shop, so we made everything to spec. My shop equipment is oriented towards prototyping, so it would not be efficient for us to produce these. However, the end goal is to invest in production CNC equipment to be able to make future products like this. During the design and prototyping phase, I worked closely with the machine shop that is making these for us to make sure that the design would be producible. It's too easy to design and prototype something that is very difficult to manufacture, so it's best to communicate with those who will be making the parts during the design phase. I shared CAD models, drawings, and pictures with them on a regular basis for feedback. The only thing that I never provided them with was a real cartridge. Now the reason for this was to protect IP and to see how good they are at machining to drawing specifications and tolerances (a test of sorts). Specifically, I did not want them to make random adjustments to dimensions just to make the cartridge fit properly. If I was judging them only by the final functionality of the machined marker, they would have failed the test. However, after checking all the critical dimensions, they passed by about 85%. Most of their dimensions perfectly matched the drawing dimensions. However, there are 5 critical dimensions that form a tolerance loop which affects the travel of the cartridge during extension. 3 of those critical dimensions were out of tolerance. They were off by +0.34mm, +0.82, and -0.20, which added up to a tolerance loop stackup of 0.96mm, which was just enough for the extension to not function properly. I mean, this was right at the edge of working. If I pushed (too hard) it would lock into the extended position, but that is not acceptable. The issues here were probably because non of these dimensions are directly measurable using calipers. 2 or more dimensions have to be measured to calculate the dimension. The QC department will have to pay close attention to these dimensions in production.

Now that I am confident in the quality of their work, I have sent them the cartridges to be used by them to check the functionality of each Marksmith body. Would it have compressed the production schedule if they had the cartridges in hand while making the samples? Probably, but they could have also used them to fudge the dimensions around to fit instead of machining from the design dimensions.

2. The width of the clip neck that passes through the body to the slider inside was changed, but the slot width was not, leaving a slot that was a bit too tight. They widened the clip neck by 0.5mm from my design to increase the strength, because the screw holes are close to the wall, but they forgot to widen the slot by the same amount.

3. The clip mounting to the slide was off-center. This is an F up that can't be justified, especially considering the high quality of the rest of their work. The screw holes were not centered, and all of the samples were like this. Someone set up the zero wrong when machining the screw holes.

Do you see the off-center mounted clip?
Do you see it now?

4. Burrs inside the slide were grabbing the tail of the cartridge. Some samples had it, some were clean. Those must always be free of burrs.

5. A radius was missing that creates a smooth transition for pushing the clip to the side to retract the cartridge. This made it more difficult to retract the clip. I prefer the smooth ramped motion as I designed it. After close inspection, what I think happened is that they messed up the machining there, and then hand filed it to match the drawing dimensions. These are pre-production samples, and as such its normal for things to get hand-filed sometimes. Anyways, they know this needs to be done right.

All these points have been discussed with the machine shop, and they are working on new samples incorporating these changes. They said it's going to take then about 15-20 days, but from experience with any manufacture, it's likely that there will be some delays.

Production Schedule

As many backers have pointed out, September is around the corner. It's going to take about 15-20 days (starting from August 19th) to complete the new samples, a few more days to ship, a few more days to analyze, document, and hopefully confirm the first production run. So that means production will begin in the second to the third week of September, and the first production run will take about 3-4 weeks. The first Marksmiths could ship in mid-October.

Why is this taking longer than the Estimated Delivery?

It's easy to blame COVID for everything these days, but it really has had repercussions everywhere that I did not consider when the project was launched. This project was launched on the second day of the first week of the stay at home orders that took effect in GA and most of the US. Things felt smooth for the first few weeks, and the govt thought all might be in the clear after that. Well, the fact that kids (including ours) have not gone back to school yet and are doing virtual learning means that the time I have to work at the office/shop has been cut in half because my wife also continues to work and we have to bounce back and forth between taking care of kids. This affects the business and factories that I work with also because they are now understaffed and less efficient since some of their employees have to stay home with kids that would normally be at school. The rest of Engineerable's team does not have children, so they are continuing to mostly work normal hours and can take care of the making and shipping stuff, but I'm the one that does new product development.

I should have engaged the machine shop to make the samples during the time that the Kickstarter campaign was running. Instead, I continued to make improvements, testing and tweaking the design to perfection, such that they only began the samples after the campaign had ended. It extended the production time, but the result will be the best marker.

The machine shop took about twice as long (2 months instead of 3-4 weeks quoted) due to delays like a broken drill bit and getting the finishes right. It was a mistake to ask them to do different finishes. I thought it would save time to machine them all at once, and then I specifically asked them to ship the brushed finish first, and not let the other finishes delay the shipment of the brushed finish. Well, the way they did it, they had to wait until all of them were complete before shipping. Lesson learned, just ask for what I need, and do other versions later.

What happened when the samples arrived? Members of my family got COVID! Fortunately, it was mild and everyone is ok, but that has put me out of the shop for almost a month due to quarantine. I know quarantine is only supposed to be 14 days, but that's for a single person. When different people in a household catch it at different times, that extends the quarantine. So, I was unable to review the samples right away. I had to review remotely with my shop machinist, and he caught most of the issues, but it wasn't until I was finally able to get my hands on them to take measurements that we were able to get down to the root cause of why they were not fully extending. It took about a week for me to review and write a very detailed engineering report documenting everything. From experience, I've learned that it's essential that every component or product has a manufacturing document and not to rely on the factory to keep track of changes. These even applies to ISO9001 and equivalently QC certified companies who are supposed to have all their ducks in a row. In the past, I have had parts made where I've spent a lot of time fixing issues (including packaging for shipping), and then I don't order them for a while, but the next time I order them it's like they have forgotten everything and we fall back to the beginning. Therefore I keep a manufacturing document of everything that gets made and send the updated version every time I place a new order.

 Thank you,
