I couldn't possibly carry around something that big with me all the time.

I prefer these for day to day cable cutting: [Link: kleintools.com]

When I know we'll be doing a lot of cutting, like demo'ing an office space or ripping out large bundles of cable, that's when our large cable cutters come out.

The scissors seem like they work forever, never get dull, etc. I just had to replace my last pair after 8 years because the foam on the grip finally fell off.
