Scotch Super 33+ for taping spines.
While not dealing with hones directly I posted this here because it deals with part of the honing process. Scotch Brand Super 33+ vinyl tape. Avoid this like the ebola virus. I just bought a nice big roll and taped several razors in preparation for honing. After honing I removed the tape and it had left ugly nasty black adhesive residue on every blade! The stuff is incredibly difficult to remove. Alcohol won't touch it. Maas won't help. Perhaps the individual roll I bought was somehow defective but I wanted to put the warning out there. Horrible stuff.
