I have several carbide tip saw blades and router bits that I need to put into storage for about yr or so. I want to put them into tupperware containers say bits in one and blades in the other. But to protect the edges I was thinking of finding that wax coating that they use when you send blades & bits out to get them sharpen.But I don't know what that wax coating is called or if there is another way.Looking for ideals and what that wax coating is called,thanks guys for any ideals and help.
