The Cut Master KA1000 is manufactured from high-tech Kevlar yarn, which provides this glove with an ANSI cut level 5 rating in laboratory testing. Kevlar, on a pound-by-pound basis, offers up to 3 times the cut resistance of standard Kevlar, allowing you to get higher protection out of a lighter-weight glove. The KA1000 features a seamless knit style for optimal fit and comfort, while its reinforced thumb crotch increases the longevity of the glove by reducing wear in that crucial spot. Their color-coded over edge prevents them from unraveling in the wash, and ensures ease in sorting after laundry.
