Perfectly mated cutter, heat treated to hold its edge. Polished high carbon drop forged steel. Useful crushing area. CHANNELLOCK BLUE comfort grips. Length: 9"-225mm Channellock uses high carbon C1080 steel for superior performance on the job, and an electronic coating for ultimate rust prevention. Most of the manufactures use two sharp edges which can eventually become misaligned, losing there cutting effectiveness over time. Channellock's knife and anvil ensure proper cutting edge alignment resulting in a clean cut every time! Also this is to ensure perfect mating and superior cutting edge life. The laser heat-treated cutting edges last 3 times longer! Not only made for durability but for comfort as well, with the blue grip handles.
