This update to the design was focused mostly around streamlining the Mk10 Mod1 updates into a sleeker package, but I also added some new features that I've been waiting a long time to able to add that I'm pretty exited about:

Type 2 titanium anodizing- Unlike type 3 titanium anodization that changes the light refraction properties of the surface to produce a variety of colors, type 2 anodization converts the outer micrometers of the titanium's surface into into a wear resistant coating with high lubricity. This process is commonly used in the aerospace industry to enhance the the mechanical properties and temperature resistance of the material, and in the medical industry to prevent wear and increase mobility of joint implants.

Precisely sharpened blades- Instead of belt sander sharpening the square edge of the 1095 steel blades as previously, they are now sander beveled at 17 degrees down to a 22 degree sharpened edge produced with precision knife sharpener.

Updated "guard" component- This is the component that partially covers a portion of the sharpened blade edge when the knife is folded. Rather than a guard that swings freely and can impede the function of the knife by being constrained into position upon opening/closing, the guard is now linked to the "arm' (a rotating component of the blade) so that if follows a set path into both positions.

Other features include 6-32 screws instead of 4-40 screws, a 1095 steel logo plate held in place by neodymium magnets, aesthetic geometry changes, and a length change to approximately 12.3 inches when opened.

Materials of components and hardware are identical to Mk10 Mod1, Which is a modified version of Mk10.

Mk10 design break down:

Knife I made

I wanted to make a knife with a high degree of modularity so that when a component is damaged it can easily be replaced.

Well I missed the earlier versions I guess. I will say that the knife is a mechanical and creative tour de force. I guess I'm wondering what problem you are trying to solve? What is it that this knife does better than any other and what are the trade offs you are making to achieve that goal?

Well for starters it looks like you can put an 8" blade in a 4" handle......

Straight to the deep questions. Excellent.
The idea I discussed in my first post on the forum: https://www.bladeforums.com/threads/knife-i-made.1868773/ , is that there's an element of modularity in this design. Where in traditional pocket knives too severe of a sharpness angle is avoided to prevent chipped blades and broken points that are only remedied by permanent re-profiling or replacement of the entire knife, the modularity allows for quick repair of damaged blade components by installing replacements that cost as much as the grocery store quality knives one could be satisfied to carry. The transformer-esque reconfiguration of components is really only a cool benefit of this modularity, but it also helps satisfy a market of people who are, as I was, bored of "new" iterations of the same folding knives that have been around since 500 BC.

Very cool.

Folks have been thinking/working on a folder where the blade is longer than the handle for quite awhile.

Reminds me of the old folders where the blade was so long it didn’t fit into the handle.

Also this folding katana:

Your knife might just be the missing link between our knife past and our knife future! ;)

Gotcha. I'm a bit more of a traditionalist, in fact I deliberately purchase replicas of ancient swords and daggers. Weapon or tool gadgetry has been around a long time, with some interesting examples inhabiting various museum collections. I think this is something like those. That's not being dismissive, just acknowledging where I think this item fits into the grand scheme of things. As I said impressive engineering, good luck with it.
