All about wood chisels

  • All about wood chisels

    At the root of all woodworking lies a simple notion: A sharp tool can quickly and effectively change the shape of wood. And for several millenia, wood chisels have served as one of the fundamental tools for cutting and shaping wood. In the classes Tim Peters teaches, his students to use them for chopping mortises, paring tenons, cutting dovetails, carving reliefs, shaping table and chair legs, and so on.

  • Take it from a pro

    Tim Peters, master furnituremaker and professed hand-tool junkie, heads the woodworking department at Orange Coast College in Costa Mesa, California.

  • First, understand the blade/handle connections

    Chisels come in primarily two styles: socket chisels or tang-type chisels, as shown in photo. That means the handle either slips into a tapered hollow socket, or it slips over a tapered square or round tang milled into the blade. Disassembled, you can see how socket and tang chisels fit together.

  • Bench chisels: Buy these first

    Fortunately, most woodworkers don't need dozens of specialized chisels. You can do the vast majority of your work with just a few common bench chisels. Bench chisels have 4"- to 6"-long blades with flat backs and beveled edges, as shown.

    Butt chisels are a subset of bench chisels, with similar design but shorter blades and handles. These chisels work great for tasks where a longer chisel proves obtrusive or unwieldly, as with joinery on small projects, such as jewelry boxes or toys.

  • Paring chisels handle fine-cutting tasks

    These chisels should never be struck with a mallet. Most paring chisels use tang-style construction, although any really sharp chisel could be employed to do some paring, slicing off thin layers of wood as you fine-tune a joint. Chisels specifically designed for paring usually have slender 6"- to 8"-long blades used for reaching deep into joints.

  • Opt for specialty chisels only when needed

    You might find these specialized chisels handy for your home shop.

    Mortising chisels. Whether you're a hand-tool traditionalist or you just don't want to fuss with setting up a mortiser or drill press, you can, with a little practice, chop mortises by hand with these heavy-duty chisels.

  • Corner chisels

    These prove handy for squaring up corners of rabbets, dadoes, grooves, and mortises when struck by a mallet. So if you don't have a dedicated mortiser or mortising chisel, you can drill out most of the waste at the drill press, and then clean up the corners with one of these. Same goes for stopped channels made with a router.

  • Crank-neck chisels

    Marrying the best features of a hand plane and a paring chisel, a crank-neck slices away material while you rest the chisel blade flat on the workpiece. The bent handle lets you grip it comfortably without scraping your knuckles on the wood. These work well for shaving off proud wood plugs or dowels and for removing glue squeeze-out from inside corners.

  • Skew chisels

    Another form of paring chisel, the angled cutting edges on these work great for reaching into difficult areas to trim away material. I use them for paring dovetail sockets because I can hold the back flat against a surface and ensure a true cut. It's best to get right- and left-facing models for use on opposing sides of a socket.

  • Consider Japanese chisels for durable performance

    The Western-style chisels I've shown originated in Europe and are perfectly adequate for most work. But in my opinion, Japanese chisels have no equal. Here's why. Japanese chisels feature two layers of steel forged together into the blade: a harder, thin layer laminated behind a softer, thick front. As a result, the harder portion holds its sharp cutting edge longer than most Western-style chisels. Japanese-chisel manufacturers also grind a hollow back onto the blades, as shown, so you have less material to remove when lapping the back flat.
