TL;DR: I collaborated with a knifemaker to make a custom. It was fun.

Sometime in October last year, I decided to stop searching for my ideal knife and just design one instead. During the summer prior, I worked on a deck-building project in which I used a different one of my knives each day. That has allowed my to figure out exactly what I needed a knife to do: cut, scrape, and pry. It was my first time designing a knife, so I stuck to simple, proven designs, and I sought help from more experienced individuals. My public design thread can be found here: http://www.bladeforums.com/forums/showthread.php/1116340

After getting close to a final design, Tim Johnson of Blackstone Knife & Tool offered to help me bring it to life.

Since I am an engineering student and Tim is a machinist, 3D-models and drawings were bread and butter in the beginning of this project.

After a few back-and-forth emails, we decided to use CPM-3V. Tim then went to work and kept me update with each step.

Rough-shaping and main bevel grind:

Polishing and skeletonizing:

At this stage, I was really curious to see if I can finish the knife myself. So, I paid Tim for the work already done and had him send the workpiece to me. From this point, there were only a few steps left: rounding/polishing, heat treating, and creating the edge. Just this past week, I finally got around to working on it and sending it to Peters' Heat Treating - great company, by the way. The knife comes back at HRC 60 with a nice, thin, maroon layer of oxidation that is quickly removed with Scotchbrite, WD-40, and elbow grease.

Now is time for the fun part: taking the 0.020" edge down to shaving sharp. Manually. With an aluminum oxide stone.
Two hours and a clogged stone later, I have my first custom-collaboration.

Now I'm sitting here with bald patches on my forearm, paper shreds in my trash can, and a proud smile on my face :D
If you are thinking of trying something similar, go for it. It is quite fun and rewarding.
 
Yup, the Razel was my main inspiration. I would have liked to get one through Jon Graham, but the orders are closed, and I probably can't afford it. Maybe in the future :)
 
Its LITERALLY a sharpened prybar....... :D:p

Im just messing with you, great job on the knife! I thought of doing something similar a while ago, but never got around to it. Maybe sometime in the future.

Ive made custom scales before, but never a whole knife. Must be pretty challenging, but very rewarding in the end :thumbup:
 
I would tell anybody who will listen to use chisel grinds on their first try at knifemaking.

The hardest parts are:

1) Making the master bevels of a double-bevel knife symmetrical

2) Lining up the holes for the tang and handle slabs.

By using chisel grinds, you take the frustration down quite a lot.
 
Have you done any testing with it yet? How does it work?

Over the past few weeks, I have used this for many food items with great success. It easily cuts apples, cleanly cuts steak, bites into onion and tomato skins, and - most importantly - effortlessly opens up coconuts.

I find myself using it to pry things without fear of breaking or dulling because the forward chisel edge is thick and purposely kept NOT razor sharp. Haven't hammered it as a chisel yet, but I'm looking forward to the opportunity.

Designing your own knife feels like the nicotine patch for knife addiction.
 
Good thing that's exactly what I wanted: a sharpened prybar and chisel :D

Dude you got a custom sharpened pry bar!! :D:thumbup:

This is the one time and only time I will say this. That sharpened pry bar is freaking awesome!
