Precision made in our own machine shop, these chisels are milled from PM-V11 steel (Rc61-63), an innovative proprietary alloy. This metal’s micro-structure makes it extremely durable, so it can withstand the impact of heavy chopping cuts without chipping or deforming as readily as other tool steels, even at bevel angles as low as 20°. Highly wear resistant, the edge typically lasts at least twice as long in use as an A2 blade before it needs sharpening, yet it's easier to sharpen than A2 steel using common abrasive media such as water stones.
