there are different methods of folding a hawk before welding it , one is take a longer piece , like the whole ferriers rasp , minus the tang , fold about 4 in. over . hammer completely flat , to the inside , then bend in u shape the rest over to reach the cutting end bring up to dull red , flux real good , start at that end with hammer peen paralell ( however you spell it) hit 3 licks reheat hammer on till you get the bit welded real good , this starts to spread and taper at the same time. this is very important, to check you reheat , remove , hold in dark place and look for shadows in it , this will show if it's welded good. i do mine with my 50 lb. little giant , with top drawing dye and flat bottom dye , made special dye i can slip onto bottom that has radius and bevel built in , this spreads and tapers at same time. i can forge weld and taper blade in one heat. now there will be lots of extra material around edges , so i can look at it and figure out which side will work best for being the top , mark out style i want it to be , cut out with band saw , best saw i ever used is a porta band stood straight up in vise , clamped by handle , built a shelf on it , works super good and blades are cheap. all that done turn around hold blade put semi formed eye in forge heat up good and drive drift down thru eye all the way but about an in. quickly grab drift by little end , lay blade on anvil face , eye off edge hit three or four medium licks to tighten around drift , flip over to opesite side of anvil face and do the other side. then look at top see if blade and eye line up straight. you can purchase hawk drift from knife supply dealer, can't tell you who, but you will have to figure it out. i made mine out of a ironworker bull pin , took me a whole day , fits my handles perfect. all for now , one finger typing tbell.
