I had to purchase a 1000 foot roll of what I call "Edge Guard". It is 1/2" wide "U" channel polypropylene that will cover the edge and grip the blade. It is the same stuff that large Lenox band saw blades come with covering the teeth.
I use it on every blade, and cover the blade edge while working on the knife, storing it, and when I sell a knife.
The good thing is it will fit any size or shape of blade with o more than a piece of tape. It has made taping the blade up needless.
The plastic sleeves from the kitchen supplies or ebay have to be the right size for the blade.
Several of the forum guys and other makers who see me at the Harrisonburg show buy it from me. I just pass it on at about what I have in it, which is a quarter a foot. Email me and I'll hook you up with some "Edge Guard". I wouldn't mention it on this forum, but I don't know of any other source for it. I had to go directly through Lenox to get it drop shipped from the maker. Without other makers using some of it, that 1000 feet is going to last a Loooonnnggg time.
