I just wanted to show off a couple of the knives I've made. The blade on the first one is 5 3/4" long and made of a circular saw blade. the blade on the second one is 4 3/4" long and made of a file. Both blades are attached using the method described HERE and reinforced with pine rosin. if anyone needs more info just leave a comment and I'll see if i can help. Thanks for looking.
