you get knife number 3.
i took an old file that was in the garage shaped it in to a blade on my top of the line harbor freight belt sander.made a handle out of some bamboo we had.filled both ends of the bamboo with 2 part epoxy for strenght.pined in the blade with a stainless steel pin.an here it is.the whole thing is 7 and 1/2 in.blade is just under 3 and 1/2.the rest is all handle.i had a lot of fun making it and i think this one is a keeper.the matching bamboo sheath has a strike bezel cut in to it for fun.thanks for looking. clint.
