Utility Cutters.

This article presents information on various cutters. Things haven't changed in the sense that there's no shortage of materials to cut— from light-gauge steel and aluminum to bulletproof fabrics made out of synthetic materials. And there still is leather, canvas, hemp, building paper and other traditional materials. Tool designers have looked at these materials and how we cut them, and they've come up with knives and shears to cut more quickly, neatly and with less strain. The knife's proportions and materials were the first things considered by the knife's designer.
