Collapsing Blade Mk11

How sturdy is the knife overall in regards to impact?

If its treated as one would a pocket knife I don't see there being an issue. Its made of grade5 Ti with spring temper 1095 steel cutting blades. Both materials are "springy", they deflect applied force in the form of elastic deformation rather that being completely stiff and prone to snapping. It's not a throwing knife or a hatchet substitute, but could be considered a typical edc knife.

IMO , an interesting novelty item :cool: ...but impractical as a functional knife :(.

I don't think this design could ever replace the rugged reliability of traditional fixed blade knives, but my goal is to develop it to the point where it could be considered a viable carry alternative. Constructive criticism has been instrumental in past development. If you have any, share with me and I might address them in future modifications/iterations.

That is a very cool piece of engineering and execution. Practicality wise, I'm guessing slicing materials would probably suffer. How much hang up do you get on the mechanism when slicing or stabbing?

For now I'll be sticking with pocketknife duty for this one. As soon as I can make a couple for destructive testing purposes I'll do so, post the results and make any needed modifications to the design. Perhaps I'll pick up a switchblade, balisong, and paratrooper dagger for some "torture testing" comparisons and make a video out of it. Would definitely be a lot of fun.
 
It’s unfair to judge it against more traditional folding knives and while I don’t see it replacing one of my EDCs due to the sheer size of it I think it’s really cool and would love to have one. I personally think it’s great when makers think way outside the box and I can totally appreciate the engineering that goes into something like this.:thumbsup::thumbsup:

Just viewed the video of opening and closing .

Yeah, it's cool novelty and a fine fidgety toy ! :cool:

But as a utility knife : https://en.wikipedia.org/wiki/Rube_Goldberg_machine 🤨

IMO , you already have the core of a marketable product ...as a cool , interesting , fidget toy knife .

Just don't try to directly compete with the mass of already available , cheaper and more functional knives .
 
Still cool as hell!!!!! Will always be cool as hell too!!! Some comparison vids would be neat.....
Great job all around...

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.
