Added version that fits blades without hole.

Utility knives are good for jobs like breaking down cardboard boxes, cutting carpeting, or slicing the painted seam on a stuck window. Other tasks can include sizing a small patch for a linoleum floor, trimming a rug pad, or even freeing a toy trapped in a blister-pack nightmare. Building paper, sheet plastic, drywall, tarps, rope, and even roofing shingles can all be cut with utility knives.

No matter what you’re doing, whether it’s opening a bag of ice melt or cutting an asphalt roof shingle, you want to make sure that you have a good grip on any dangerous tool. The best knives have some kind of finger groove, because it’s an actual physical impediment to slippage and has less to do with hand strength. This isn’t to say that you want a light grip, but with your fingers even slightly “hooked” into the tool, they’re far less likely to slide off.
