I've been using a boxknife, or at least what I call a box knife to cut sections out of drywall as I put it up (vent holes, that sort of stuff). Anyway I find that for anything over 1/2" drywall that box knife really sucks at cutting.
How do the pros cut drywall, I've seen them do it at work when they were constructing my server room, but it just looked like they were using box knives to me - but they went so much more quicker. Is there a special type of blade or knife that works best for drywall or what. It's not like I was being dainty or something with the blade.
