+1 on the Scotch gift wrap cutters, picked one up for $2 after hearing about it on here and have been using it ever since. Just have to be careful if you're slitting something that's thin and/or not laminated, the tip that goes between the backer and material can get caught on the material and poke through. Not a big deal if you catch it, just pull it back a bit and push up and out, but I did ruin one print before not paying attention. The tip caught halfway through and the the material was slit along with the backer from that point on. Seems to catch more often on areas with heavy ink coverage as well. Any of you other guys that use these have any tips on how to keep it from getting caught? I was thinking maybe rubbing a drop of baby oil all over the tip but I have a feeling that's gonna screw with the adhesive on the material.
@ucmj I think he's referring to cutting the backing paper only, although that's a pretty nifty little tool too.
