We are pleased to offer the growing line of socket chisels made by Ken Hertzler of York Pennsylvania. A big feature of his chisels is that they are made from O-1 tool steel, which is uncommon with today’s chisel manufacturers. O-1 will take a very keen edge, hold that edge for a long time, and is easy to sharpen. Many hand tool users prefer this type of steel over the more common A-2 alloy.
His chisels are also surface ground on the top, bottom, and sides after heat treating the bottom portion to Rc 58-60 Rc. This ensures flat and square surfaces with a very fine finish. They only require a light honing on the cutting edge and back to produce a razer sharp cutting edge.
The handles employ a tapered tang that locks into the socket of the chisel. A solid rap will firmly seat the handle into the socket. Socket chisel handles are less likely to split in use, and can easily be removed for replacement if needed.
1/10″ wide mortise chisel. A narrow chisel is essential for side escapement plane making, and it will certainly find other uses when necessary to get into confined spaces. The usable portion of the blade is about 4″ in length, and tapers from 1/4″ tall just behind the bevel to 3/8″ where it joins the socket. Overall chisel length including the handle is about 9 1/4″. Handles are now hard maple. Price is $97 plus shipping.
Large, 1″ wide firmer chisel. This chisel was designed for those looking for an extended reach and longer length for better control of heavy paring or chopping cuts. The blade tapers in thickness down to 1/8″ at the cutting edge. The sides are square (hence the firmer name) to the top and bottom, which will help prevent this chisel from undercutting an adjacent, vertical surface when paring against, such as when paring a tenon shoulder. The bevel is ground at 25 degrees. All flat surfaces of the blade have been surface ground for a smooth, flat finish. Only a light honing will be needed for the initial sharpening. The full width portion of the blade is about 7 1/4″ long, and when the socket is included, is over 9 1/2″ long. Assembled with the hard maple handle, overall length comes in at about 16″. This chisel works very well when pared with the miter jack vise, having enough reach to extend all the way across the jaws in all set up configurations. Price is $170 plus shipping.
