Hello all.

I am a machinist with a growing collection of bits of material. I am also an avid firearms enthusiast and have been learning some basic gunsmithing.

I have recently acquired a large piece of D2 tool steel. It's about 7.5" by 10.5" and 1" thick. It's in an annealed form I believe and tests out at 42 rockwell currently. I've machined this stuff before and know what it takes. If needed it can be heat treated to over 60 rockwell which is damn hard. Used for cutting dies and the like.

Are there any parts or gun tools anyone can think of that I could whittle this chunk into?

I'm drawing a blank. Thank you in advance for any responses.
 
D2 is designed to take impact, like for punching or cutting tools. Yes it would make good knife blades. For general tooling, A2 is better because you can machine it out, heat it up to cherry red and let it cool and it is hardened.

If you do go to cut the D2 with a saw, don't use coolant.
