This is the second iteration of a flipper design I did a couple years ago. It is both lighter weight and more refined.

This is the Kickstarter for my generation 2 Umbra flipper folding knife.

Look for me on instagram. @jacksonknifeandtool 

If you are interested in seeing the first generation design, do a google search for "Steve Jackson Umbra" and you will find what you are looking for. I only made 5 of them. 

For now, I am limiting shipping to the US and Canada only due to the fact that I am not an expert in international knife laws. If you live in a country that will allow the shipping of knives through customs and are willing to take the risk on shipping, contact me and I will add your country. 

SPECS

.145" PSF27 tool steel blade

3.2 cutting edge

3.7 blade length

OAL 8.97"

Handle material 6al4v grade 5 titanium

I am offering it in 2 variants. A 3d machined contoured 6al4v grade 5 titanium version, as well as a flat handle, beveled 6al4v grade 5 titanium version.

I will be offering various finishes and anodizing options in the surveys at the end of the campaign. I want to try some new finishing tools.

On the flat handle version, anodizing will be limited to the backspacer and pocket clip only.

Above is  Quick video of the machine preparing my blade blanks to be fixtured for machining. 

The blades will likely be made of psf27 tool steel as I intend, if not (due to supply shortage or something along those lines), something of equal or greater quality. 

The blade is on bearings, and the stop pin is hardened.

My pocket clip design incorporates delightful geometry.

I am fully also machining out the internal structures of the titanium frames for an extreme weight savings, leaving behind only a skeleton with some titanium skin on top. Both the flat and contoured versions of the handles will be skeletonized in such a way. 

Removed for weight ; )

I will be making all the parts except the hardware, like screws and bearings right here in NJ. 

Support USA small business and grab an Umbra today.

Thanks,

Steve

UPDATE: I just added a lower tier. It is the same as the flat one, however the insides of the frame will not be skeletonized. 

Risks and challenges

None at this point. During the first kickstarter I knew exactly 0 about CNC milling. Now I know quite a bit more than that.

If my machine breaks, I am an expert mechanic and the Haas factory outlet is nearby for parts.

I have the tools, I have the fixturing done, I have the programming done (I am sure I could optimize it a little, but that will happen as I find small places to go faster), I already have a starting supply of materials. I even have some of the parts already made.

The process is worked out for the most part, and is pretty efficient.

My most serious concern is selling so many that my equipment is insufficient, however if that's the case I suppose I will be able to afford more machinery. ;)

I did a lot of the preparations already so I am less likely to blow my deadline.

Shout out to Blowndeadline Industries .

I am ready to do this I just need some customers, additional materials, and consumables. Maybe more machines if this blows up lol.

Cheers,
