Hi Mike. Of course! Those heat treat manuals are just a starting point. from there experience helps a lot. I learned a lot from heat treating my own punches and dies as an apprentice, and that's...

Not at all. Thanks, that's the help I'm looking for.

Blade is 6/8, with a 30deg incl angle. I usualy sketch things out on paper, then create solid models where things really start to come...

Some changes I'll be sketching out later tonight:

Thicken material to about .187"-.200".
Increase blade profile closer to spline.
Design a derlin or alu-bronze washer for the pivot, OR,...

I've got an older one that I use, worn but I keep it sharp.

Other than the blade thickness that I agree on increasing, what do you see as being an issue? Bear in mind this is a sketch and there's...

Ah, yes I understand. I respect the end purpose of my product immensely, hence joining here :)

The metalurgy and manufacturing process is relatively the same from a razor to a knife to a shearing...

I hear you, but I get paid for my other work and the knives are for actual special forces guys, who will use them in action, so that takes priority.

Here's a belt I made using primary edm. Made...

That's the plan. I have a bunch to learn form you guys on this topic, and I hope to be able to help with regards to metalurgy and manufacturing process in return. This will be a 'spare time' project,...

I have Wire EDM machines to use (will cut through the hardest material like butter) and surface grinders with magnetic sine vices that pour coolant on the work. Work hardening won't be an issue. It's...

Agree. It's .125 in that sketch. Thinking .187 at the spline. What do you think. It will be a wedge grind. Of note, even a .187 on a 9" oal fighting knife is very stiff. The material I'm using for...

This thread can serve as a build diary of sorts for something I've wanted to make for a while:

More to come as I have the time to work on it.
