Seems like a lot of work for what's basically a nail. Why not use square keyway material?

And that comes from one with a nym of rusty bolt http://bbs.homeshopmachinist.net//biggrin.gif http://bbs.homeshopmachinist.net//biggrin.gif

If the spikes are anything like the rail it is a very high quality, high carbon steel.

But more likely they are a lower carbon steel but still of a high quality. Take a file to them. JRouche

No. They're not anything like a rail at all. As a matter of fact they're pretty soft. If not whacked just right with the sledge, they bend.

They cut real nice, about like cold rolled. I thought they would be harder.

According to a variety of smithing and knife making sites they come in two grades. 1018 mild steel and if marked on the head HC they are high carbon in the range of 1030 or 1045 steel alloy.
