I have a box of ~1000 (void) gift cards of various colors from my old job because I expressed interest in making a mosaic from the colorful plastic bits.
My question is: how to cut them? I've tried:
- Kitchen Shears: the dull edge is perfect for a plant stem, but it just chews up the tough plastic. It even gets a little opaque white where the cut stresses the material, which ruins the color.
- Paper Cutter: good for one precise cut at a time. Takes a long time and dulls the blade rather quickly (and I don't know how to sharpen it).
- Paper shredder with credit card attachment: Starts off pretty good, but the blades visibly dulled after a dozen and only cuts in one direction, which necessitates another method anyway.
Is there some kind of specialty cutter for plastic I could co-opt for my project?
