A while back I bought some of Don Hanson's wonderful W2 round and had it power-forged into bar stock. From one of those bars, I pounded out my first forged blade last week. I heat treated it last night and finished out the blade today. I'll put a handle on this week and post pics.
Here's the blade after I clayed it:
I used satanite for the clay. First I applied a super thin layer of satanite, dried it with the heat gun, and normalized the blade. Then, I brushed off the first layer of satanite, applied a new one, and then applied the thicker clay (around 1/16") to the blade. I again dried it partially with the heat gun prior to putting it in the oven which was around 450F (turned off and cooling down) after normalizing. After a few minutes, I brought the blade up to 1450F and held it there for 15 minutes. I quenched in Park's #50 at 78F. In for one-thousand, two-thousand, three-thousand; out for one-thousand, two-thousand, three-, and back in the oil to cool to oil temp. The satanite came off nicely after it cooled down. I tempered the blade and that gets us to today.
I cleaned up the flats using the disc grinder (I LOVE that thing), and cleaned up the bevels and plunges on the grinder. I went through the grits from 400 to 2000 by hand, and then I cleaned with alcohol and etched in a 4:1 ferric chloride:water solution for a 30 count. After it came out, I polished with a paper town, red rouge, and WD40 followed by 0000 steel wool and WD40.
I'm very pleased at how it turned out, though next time, I'll have my clay terminate a little higher on the blade to raise the hamon.
Thanks for looking!
