Thanks guys. I just leave a piece of .035 stainless wire hanging out of the mold I modified and tie a loop in the wire after I slide the blade on the wire. I bend the wire around a good ol small craftsman screwdriver. It is super easy and virtually indestructible. Be sure to tape over the blade with painters tape before you paint. I put my screwdriver in a bench vise to hold it too. Hope this helps. I can post a close up if you need to get a better look.
