Sharpening

Everything on this bench that cuts has to be brought back to an edge, sooner or later. This section covers the stones, the angles and the small tests that tell you the job is done.

The sharpening corner of a workshop with stones stacked on a shelf, a can of oil, a leather strop and a folded towel, window light from the left, wide view.
The sharpening corner, with the stones kept together on one shelf and a towel that never leaves it.

Sharpening is the one skill that changes every other job on the bench. A chisel that cuts cleanly makes a hinge recess look deliberate; a blunt one tears the fibres and leaves a recess that has to be filled. The same goes for a plane iron, a knife, a pair of secateurs and the teeth of a hand saw. Almost everything written here starts from that: the edge is not a detail at the end of the work, it is the thing that decides whether the work is worth doing at all.

The approach in this section is deliberately narrow. Two stones and a strop will sharpen nearly every tool a household owns, so the entries below concentrate on getting a lot out of a small kit rather than on comparing expensive ones. Where a piece of equipment does earn its place, the entry says exactly what it does that the cheaper route cannot, and what it costs in time as well as money. Angles are given in degrees, grits on the Japanese scale, and every method described has been used on a tool that went straight back into service afterwards.

Hands holding a bevel edge chisel flat against a soaked grey water stone on a wooden bench, slurry pooling at the edge of the stone, daylight from a window on the left, close view from above.

Sharpening a chisel on water stones

A 1000 grit stone, a 6000 grit stone and ten minutes at the sink. The sequence, the angle you can hold without a jig, and the two tests that tell you the burr has gone rather than moved to the other side.

An oilstone in a wooden box and a soaking water stone in a plastic tray side by side on a workbench, a small oil can between them, cool north light, close view from above.

Sharpening

Oilstones or water stones, and what changes

Speed, mess, storage and the price of the first set. The honest comparison for someone who sharpens four tools a month rather than forty, including what happens to each type of stone when it is left unused for a year.

A grey water stone marked with a pencil grid resting on a diamond plate in a shallow tray of water, a hand steadying it, bright window light, close view from above.

Sharpening

Flattening a water stone, and how often

A hollow stone rounds every edge you put on it. Checking for flat with a pencil grid, and the three ways of taking the hollow back out, with the one that wears the stone least.

A chisel held against the wheel of a bench grinder with a fine spray of sparks and a jar of water on the bench beside it, dim workshop, close view from the side.

Sharpening

Grinding a new bevel without burning the steel

Blue at the tip means the temper has gone and the edge will not hold. Light passes, a jar of water at the elbow, and the signs to watch for on a chipped or badly rounded chisel.

A hand saw clamped between two boards in a vice while a triangular file is worked across the teeth, bright task light from above, close view along the tooth line.

Sharpening

Sharpening a hand saw at home

Jointing, shaping, setting and filing, in that order, with a triangular file and two scraps of plywood for a saw vice. Why a rip saw is the one to learn on.

A leather strop nailed to a block of wood with a bar of green compound and a plane iron resting on it, on a bench top scarred with use, warm lamp light, close view.

Sharpening

Stropping, and what happens to the last burr

A strip of leather glued to a block, a bar of compound, and the direction that matters. What stropping removes, what it rounds over, and how many strokes is too many.

Sharpening runs into the other sections quickly: a plane needs its iron flat, and a chair repair needs a chisel that pares end grain without crushing it.
