It's been a while since I posted here, but I thought I'd share this. I've been getting into blacksmithing as a side hobby, mostly to make woodworking tools.
After seeing the beautiful hand saws Brian of BearKat Wood ( http://lumberjocks.com/bearkatwood ) creates, I offered him a trade for some forging. He took me up on the offer and I set out to make him a fancy drawknife. I initially forged a tiny one just to learn the process, then moved on to making these two. I sent the larger one to Brian and kept the smaller for myself.
I made these drawknives from bicycle chain forge welded to good tool steel backers for the cutting edge and extra strength. This is known as "chain damascus" in the knifemaking community. The smaller one has an antique file as the backer (W1 steel most likely), while the bigger one has a 1080 steel backer. It's all hand hammered by my feeble arms on an anvil, as I don't have a power hammer or press. I heat treated the blades by heating to non-magnetic (about 1500 deg F) and quenching in warm oil, then tempered at 425 deg F in the kitchen oven, followed by softening the tangs in the forge. I acid etched the blades after polishing to bring out the link and rivet patterns.
The handles are turned out of redheart with copper ferrules, finished with amber shellac and renaissance wax. I drilled them out on the lathe most of the way through, then continued the hole from the other end freehand. On the smaller drawknife I chiseled out the remaining area to insert the tangs (which didn't fully work, one of the handles cracked and needed repair), while on the bigger one I burned them to fit by heating the tangs in the forge and inserting repeatedly (being careful not to damage the temper on the main knife body). The tangs pass clear through the handles and are peened over washers to clinch the handles in place. I also used medium CA glue in the hole to keep them extra secure.
In exchange, Brian sent me a beautiful 13 ppi tenon/carcass rip saw with a goncalo alves handle custom fit to my hand. It is incredible, I admire it every time I enter the shop:
