It is a 30 x 75 running w pattern. I have done these in many combinations, 18 X 18 20 X 40 etc.
The secret for this particular one is draw the billet to 1/4 inch thick.
First weld a 30 layer billet and than invert the billet with the layers up and draw to 1/4 inch
Cut into 5 pieces. Etch the ends, stack and align the pieces so you show the w's, weld and draw to 1/4 inch again.
Repeat the above step for 25 layers. Again draw to 1/4 inch.
Repeat step one but only cut into three pieces for 75 layers and weld. Do not draw this piece. Cut into as many pieces as you are comfortable with welding and no draw. Than remove the handle. Invert the billet with the pattern up. At his point I run a bead down both sides and add a new handle than start the draw. That's all there is to this one.
My buddy Bill Burke and I made this one. The photo below is the same pattern as the other however only drawn to 1/2 inch between welds. So it shows how the manipulation on the same billets can give you different effects. I also tweaked the edges on this one.
This is a profiled blade and hollow ground out of the first billet. You can see how grinding this type will not erase the pattern However if you want to forge the pattern will take on a different look.
Soooo many possibilities from basic patterns when you have too much time on your hands.
