New technology from Heritage changes the molecular structure of the steel compound penetrating and hardening its surface to an incredible Rockwell 70! That hardness produces a cutting edge that lasts four times longer than previous cutters. It easily cuts through Kevlar and will outlast any other cutter currently on the market. Hot drop forged from a special steel alloy, and precision ground, these shears will stay sharp and resist rust and chemicals better than other shears. They feature the Heritage ergonomic handles that provide a comfortable, natural grip. The overall length is 10" with a cutting length of 4-3/4". 2 lbs (1Kg) shipping weight.
