Too much time on my hands. pic

This is a throwing spike I just made from O1 tool steel, for the 2001 World knife throwing championship in Phoenix next week. 12" long, 1/2" round stock. Free hand grind. (Balanced on an 1/8" drill bit)
I plan on blueing these. I need to know how to get a reliable 45-50rc on this steel if someone knows

Your help and comments are welcome!

Quench in oil, 500 to 550 deg temper. Blue color to dark people should be good.

You can't do this on a lathe

Triangle blade. Handle will get an OD Parachute cord wrap.

Throwing exerts a surprising amount of stresses on a spike or knife, annealed steel will bend without too much difficulty. I believe he said his were 12" long...I've got some spikes I made of A2 that are only 9 inches long and 3/8" thick but have not heat treated...300 throws and I have about a 10 degree delineation in one. This was a while ago though

Neat spikes tho. I'd buy a set from ya if I could.

Shinryû.

 

They are going to get some real world testing next weekend. 16th thru the 18th. After that if they pass muster I will be glad to sell some . They will be selling in sets of Three.
