@Stephie Would have suggested it outright but apparently it is not a common household item.

Well, the OP is from Boulder, Colorado, so he could just wait until a really good winter freeze and do it outside en masse after freezing in the home freezer. :)

<p>There are a couple of options that would easily cut the gift cards. The first would be aviation snips or tin snips. Those are available at major hardware stores like Ace, Home Depot and Lowes. The other option would be industrial shears. They look like scissors, but the separation between the two blades is different than for fabric or paper. They are also available at major hardware stores. Both options would also be available from Harbor Freight online and in stores in the US. </p>

<li>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.</li>

Have you tried regular old scissors? (Not suggesting they'd work better than what you've tried, because I don't know whether or not they would, just asking whether you've tried them.)

Regular scissors (the kind for cutting paper) were too lightweight, and if nothing else, my hand would have fallen off after a couple cuts from the exertion it took.

I've never tried them for this purpose, but do you have tinsnips around? They're for cutting metal, so gotta figure they're a little less hard on the hand than normal scissors.

@JohnCavan you would need proper flat tinsnips rather than the aviation shears sometimes sold under the same name -- mine at least would give a rather uneven cut.

I have not tried it, but from comments at work, (we work with different plastics) metal tools should work. So metal cutting shears and maybe fine toothed metal saws.

# How to cut gift cards in order to make a mosaic?

(Asked by: username_0 on 2016-09-17)

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?
