Bench Chisel 3/8 inch PM-VII
Veritas Code 05S21.06
These chisels are among the first edge tools 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 degrees. It is also highly wear-resistant; with an edge typically lasting at least twice as long in use as an A2 blade before it needs sharpening. Despite its toughness; it is as easy to sharpen as A2 steel using common abrasive media such as water stones.
The chisel blades taper from shoulder to tip for strength and rigidity; and have parallel sides and true bevel edges for clearance and minimal friction when working into an angled corner or a tight recess. To ensure the face of the blade is both smooth and true; we lap each blade to a flatness tolerance of ñ0.0005 over the entire surface. The blade and handle are connected with a tang and a socket-like ferrule.
Flats on the tang prevent the handle from rolling. Each chisel is superbly balanced, with the center of gravity close to the tang/socket connection.
The hard maple handle has been torrefied, a heating process that changes the structure of the wood at the cellular level, stabilizing it against swelling and shrinkage caused by humidity changes. Contoured to fit the hand nicely, the handle has a domed end that resists chipping from glancing mallet blows.
Blades range from 3-5/8" to 5-1/8" long. The 3/8" and smaller chisels have 30° primary bevels; the others are 25°. All have 2° micro-bevels and require only final honing before use.
Made in Canada.
