A customer handed me a rail road spike and says he wants a knife made forged out of it.
1. What do I quench it in ?
2. How do I heat treat it?
Tomorrow I'll give it a spark test and have told him I had doubts about the quality of the blade but I guess the heart wants what the heart wants.
Years ago I had used Rasps and files for my blades never a rail road spike.
Any suggestions ?
slit it and weld in 1095 or just call it a letter opener.. the Best that a spike can be is around 35-40 points of carbon so not really enough to get hard enough for a knife.
I know it's what he wants. To me just a box opener and not even a good one but I'll give him the best one I can I guess.

Hi Dave,
I'm going to warm this subject up again.
Start by doing a search on "Super Quench". It will harden low carbon steel better than anything else. A water quench alone will do nothing to mild steel.
Of course it will never be a "knife", but it will surprise you. I did a spike after I read about super quench. I got 50 cuts of sisal rope.
I hope I don't get in trouble, but here is a link to another forum where I posted my results.

Thanks Bob it did seem to go by the wayside and I will take that into consideration and check it out. I did forge the spike and heat and quench it and of course in my opinion had very poor results. It barely hardened I do have a source for some spike higher in carbon so I'll get some of those and try again because the idea came out kind of nifty even though I messed the angle up. My son uses the machine and readjusted the Jig and I never checked the angle before I used it. I posted it don't be to critical first in 25 years and done the way I liked it.
