How to Sharpen Woodworking Chisels

A cheap chisel that's sharp cuts better than an expensive one that's dull, which is why learning to sharpen is the best money you never spend. Sharpening is not a dark art — it's three ideas repeated: flatten the back once, grind and hone the bevel, and remove the burr. Do those and any of the chisels in our chisel roundup will cut cleanly.

Flatten the back — once, properly

A chisel cuts along the meeting of the back and the bevel, so the back has to be dead flat near the edge. New chisels rarely are. Work the back flat on your coarsest stone until the area behind the edge is uniformly shiny, then follow up through your finer grits. You only ever do this once per chisel; after that you maintain the bevel and touch the back lightly.

The grits that matter

You don't need a drawer of stones. A practical progression is a coarse stone (around 300–1000 grit) to establish the edge, a medium (1000–4000) to refine it, and a fine stone or strop (6000+ or a leather strop with compound) to polish it. Whether you use water stones, diamond plates or sandpaper on glass matters far less than moving through the grits in order and keeping a consistent angle.

Angle: keep it consistent, not perfect

Most bench chisels are honed around 25–30 degrees. The exact number matters less than holding whatever you pick steady from stroke to stroke. If you can't hold an angle freehand yet, that's what a honing guide is for.

Honing guide vs freehand

A honing guide clamps the chisel at a fixed angle and rolls it across the stone — foolproof, repeatable, and the fastest way for a beginner to get a genuinely sharp edge. Freehand is faster once learned and needs no gear, but it takes practice to hold the angle. There's no shame in a guide; plenty of excellent woodworkers use one for life. If you bought a budget set that came with a guide, use it — it's often the most valuable thing in the box.

The burr tells you it's done

As you hone the bevel, a tiny wire edge — a burr — forms on the back. You can feel it by dragging a fingertip offthe back edge (never along it). When you can feel a burr along the whole width, that stone has done its job; move to the next grit. On the final grit, remove the burr by working the flat back a few strokes, alternating with light bevel passes, until it's gone. A sharp chisel will slice a strip of paper cleanly and pare end grain without crushing it.

Keep it sharp with a strop

The trick to never facing a dull chisel is to touch it up often. A few strokes on a compound-charged strop between tasks keeps a keen edge for a long time and puts off the full stone session. Sharpen a little and often, and the whole chore mostly disappears.
