Forged my first real tomahawk this weekend!! I started out trying to forge a billet of chainsaw damascus. It cost me a few gallons of sweat, propane, and beer - not to mention the ire of my wife for the steady stream of profanity that I let loose when the billet failed to weld. Gentle creature that she is, she suggested making something else, so I thought I'd try the next "tall order" on my tall order list - forging a tomahawk out of a ball-peen hammer head. I'd gotten 3 of them (and some other good stuff) from a junk dealer at an area flea market. I tried forging a tomahawk from one about 4 months ago, but the hammer part cracked when I tried flattening it. So I put the hammers away, and did some other stuff with more "respectable" steel, and just sort of forgot about them. I started heating this one up, because I'd been doing some research that led me to believe that I had previously tried to work the steel at too low a temperature. This weekend, I made sure that I got the steel REALLY hot - from the color, it was close to welding temp. It took an insane amount of time, cost me some more propane and beer, not to mention a sore hammer arm and a blister, but it worked! It's not perfect, but it's still pretty darn good for a first try. I like the forge marks, so I'm going to leave them instead of smoothing it down with my belt grinder. I still have some work to do on it, but when it's finished I'll post a pic. In working this stuff, I found a totally different experience than I've had with railroad spikes, O-1, and 1084 - which are pretty much all I've used. This stuff was harder than a coffin nail!! Hard to get to heat, but held it's heat for a long time, until the blade started to thin. But man! the stuff was hard to shape - definitely not something I'd try every day (without a power hammer at least...). Anybody have any idea what type of steel might be used to make ball-peen hammers? I know it was made in the USA, but not sure of a year or even a brand (that stuff was worn off the side). Would like to know what kind of steel could be that damn hard. This stuff was like the rock of Gibraltar even after I was done forging! I bet it's still hard enough, even without normalizing and tempering, to take a good edge and hold it.
