My mark is in two stamps: Wayne and Coe.
I made it in Machine Shop class at Appalachian College in Jasper, Georgia. A graphite "original" was made on the CNC milling machine, then cut in D2 on the EDM (electric discharge machine). It was originally all 9 letters in one stamp but I found that to many letters to stamp all at once. I then cut into two stamps. I now use the press to imprint deeply on my work. Many blacksmiths use "touch marks". I feel that it is important to use your complete name. After all, someone might want to find you and get you to make something for them. I notice that knife makers more usually use their names.
