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.

The features that hold the assembly together double as pivot points that allow the components a limited rotation

I also experimented with laser engraving of color anodized titanium.

Anodization does not seem to have an effect on the process and engravings retain all quality and contrast nicely.

The knife is made of grade 5 titanium with 1095 steel blades and 18-8 stainless steel hardware (screws, standoffs). Since the blade is an assembly of smaller, weaker parts, The Titanium and 1095 steel have a spring temperament to prevent immediate breakage where stress is present.

The white Handle parts are polyethylene terephthalate that have been 3d printed at 100% Infill and converted into isotropic solids via baking the parts in fine compacted salt to increase strength and surface finish ability. In addition to being quite strong the polyethylene terephthalate is heat resistant, self fire extinguishing, non-toxic and chemical resistant. it can be cleaned with acetone.

The primary design challenge was in arranging the latching system to take all play out of the extended "ready for use" configuration while allowing unrestricted rotation of components into the "collapsed" configuration. I have been serviceably successful in doing so. Admittedly some luck may have played a part in this.

I will be carrying it and using it in a "pocket knife" role to asses it's performance and hopefully any design aspects in need of being improved upon will come to light.

Until then I'm interested in what "knife heads" think about it

Wow that is wild looking ! Good job brother !

Kudos for your innovation and execution, but I am not a fan of Rube Goldberg knives.

 

[Hvactech]

Man the more I look at it them more I'm amazed ! I've got mechanical talent but nothing like that ! You should be very proud of It!

 

[pholder]

What the Sam Hill, see what I did there. Very interesting

 

[midnight flyer]

I admire the craftsmanship and execution of design. Really nice.

Not sure how it would do in my dirty, sweaty pocket full of sawdust and other debris!

Nice knife, though.

Chip's gotta see this WValtakis

 

[MolokaiRider]

It's definitely interesting!

 

[DocJD]

This thing succeeded apparently , so why not yours ?

Overly complex for practical hard use work or anything dirty , but interesting and innovative as a mechanical knife toy .

 

[abcdef]

But will it cut? Just kidding. Impressive.

 

[DocJD]

will it cut?

It's made to "transform" !

Cutting , keeling , or cleaning ...not so much .

 

[KenHash]

Very cool. I like it.

 

[killgar]

A very nice work of mechanical art, but much too complicated for a simple cutting tool.

 

[1911bphil]

That looks awesome. I will buy one whenever you are taking orders.

Let's see a video!

I love the mechanical thought that went into this design.

As for it being a practical knife, it looks like it won't cut deeper than a few tenth of an inch. That sort of limits its usefulness, beyond perhaps collector interests.

 

[unwisefool]

Uh, which part is the slicey bit?

 

[Stacy E. Apelt - Bladesmith]

Interesting knife. Not sure if it will be practical because of the complicated mechanics Are you Joseph Varner?
