How tools actually work, and how to choose one

A marking gauge is a hand tool that scores a thin, consistent line parallel to an edge of a workpiece, using a pin, wheel or knife locked at a fixed distance. Unlike a pencil, it produces a physical groove that a saw or chisel can register against, and it holds the same distance every time … Read more
A rasp has individual raised teeth punched into the metal, which lets it remove wood quickly but leaves a rough surface. A file has fine parallel ridges cut across it, which shapes metal (or wood) more slowly but leaves a smoother finish. Rasps are for fast, coarse shaping; files are for refining and smoothing. What … Read more
A spokeshave is a short-bodied hand plane, held with a handle on each side, used to shave curved and tapered surfaces that a longer plane can’t follow. It’s the tool for rounding chair legs and spindles, shaping tool handles, easing curved edges, and refining any shape a bandsaw or spokeshave itself has already roughed out. … Read more
A card scraper is a thin, flat piece of hardened steel, usually rectangular, with no handle and no moving parts. Woodworkers flex it slightly and push or pull it across the surface of wood, where a tiny burr on its edge shaves off gossamer-thin curls instead of dust. It levels tricky grain and glue lines … Read more
A mallet delivers a broad, controlled push of force rather than a hammer’s sharp, concentrated blow. That difference protects chisel handles, dowels and joints from splitting, and lets softer mallet faces move parts without denting or bruising the surface a steel hammer would mark. What does a mallet actually do differently to a hammer? A … Read more
A socket set’s drive size — usually 1/4″, 3/8″ or 1/2″ — refers to the square drive stud on the ratchet and the matching square hole inside each socket, not the size of the nut or bolt being turned. It tells you roughly how much torque the set is built to handle and how bulky … Read more
Metric spanners are sized in millimetres (like 10mm or 13mm), while AF (“Across Flats”) spanners are sized in imperial fractions of an inch (like 1/2″ or 9/16″). They measure the same thing — the distance across a bolt head’s flat sides — but in different unit systems, so the two rarely swap in cleanly. What … Read more
A screwdriver’s tip type changes how much grip it gets on the fastener head, how much torque it can transmit before it slips or strips, and how easily it will “cam out” under pressure. Different tip shapes exist because different fastener heads need different amounts of grip, precision and slip resistance. What does a screwdriver’s … Read more
Pliers grip and often cut, pincers are built almost entirely for pulling nails and fasteners by rocking on curved jaws, and nippers are dedicated cutters with no gripping face at all. The difference comes down to jaw shape and what the pivot is designed to do with leverage. All three sit in the same drawer … Read more
A combination square is a measuring and marking tool built around a steel rule that slides through an adjustable head. The head locks the rule at 90°, at 45°, or anywhere along its length, so one tool checks square, marks angles, measures depth and sets a marking gauge — which is why it gets picked … Read more
About what you read here. Everything on Find Tool is general information and our own editorial opinion. We research carefully and we say when the evidence is unclear, but we can be wrong, things change, and no article can know your particular situation. Please do your own research and make your own judgement rather than treating anything here as the final word. Prices, products and specifications around tools and workshop equipment change constantly, and what suits one person will not suit another. Check current details yourself, and where a decision involves real money, safety or something you cannot undo, it is worth confirming with the manufacturer, or a qualified electrician or tradesperson before you act.
