Hi Guys,

A couple of people asked if I would do a WIP of how I start my knives from start to finish. I'm on vacation right now so I had a little time to do some design work. This is my third design that I will be doing called the "Vettore". I'll be doing a series of post on this thread continuing in January after I get back.

Here is the first stage, the CAD Design. During this stage I build the CAD model making sure all the features and mechanisms work, including doing model analysis for MOI and CG stuff. This model in particular has all matching lines open and closed, which is a real pain sometimes.

Next up will be printing 3-D prototypes and templates that I use to profile and cut the materials.

Very cool, thanks for sharing! That's am amazing skill you have there to use cad. looking forward to it!
 
Hi All,

Here is the finished knife throughout the stages:

It turned out pretty close to my original concept. Only thing I didn't do was the fuller on the blade, I'll do that on the next one. After grinding the blade I just liked it as is.
 
Mike - You've progressed very far in a short time and I always love watching your process. Keep it up brother!
 
Now that is NEAT!!! model in CAD, print a 3D pattern using a 3D printer, then use the printed patterns to make final metal parts. NEAT!! I'll bet the 3D printed parts would assembly as a working protype?

BTW, which CAD program are you using?

Thanks Guys!

@Ken,

I use Creo (Pro-engineer) it's the industry standard. I'm a mechanical engineer and have been using it for a very long time, from military projects, to commercial to aerospace. It's a little complicated to learn but once you have, you can do every design imaginable.

I have used the 3D parts as prototypes and assembled them. That's how I design my knives before cutting metal. A great tool to have.
 
I've been retired from engineering almost 5 yr, but still had never heard of Creo (Pro-engineer) before. I used AutoCAD in 2D for so many years drawing up electrical control circuits, so never had much need for 3D work. The mechanical folks did all the 3D work.

Good job.
