I forged these from those [anti creep] brackets that come from the RxR
They were hardened with 1/16" left on the cutting edge. These blades were clay hardened with a Borax coat. I use the borax to shield the blade from decarb and to bind the clay to the surface of the steel. I apply the borax on top of the clay and the steel as the temp comes up in the blade. It will flow over the blade and the clay as the temp. moves toward critical. The borax will flow into all the recesses where the clay meets the blade and the future hamon will appear. You will notice all the blades have a double hamon except the second from the right, [laying flat]. The clay was applied over the top of the borax on this blade. I believe it is because the borax is not there to fill the voids letting the quench move up into the clay. The best thing to come out of this tecnique happens after the quench. The hardened edge is almost void of scale and there is very little on the rest of the blade. Easy clean up. Jams, Fred :thumbup:
