Nice, particularly for your firsthawk. It should definately do the job.
I have to tell you guys, HC rail road spikes are equivalent to 1040 steel. The High Carbon ( HC ) is a bit of a misnomer. They have more carbon than normal spikes which are 1030 steel. Even when quenched in superquench they dont hold an edge for very long, to low of a carbon content for that.
I enjoy making rail road spike hawks and knives. They are really cool and fun to make. Ball peen hammers tend to be high quality steel and if you hit garage sales and flea markets you can often get them real cheap.
If you use superquench you can get rail road spikes a bit harder than quenching in oil or water. Another trick is to get some case hardening powder from Brownells and follow the directions. It hardens the surface of the steel by adding carbon to the surface under high heat in the forge.
