Hand saw: what it does and when to reach for it

Learn to use a hand saw safely and accurately to cut a straight line through timber.

HN-01Know what a hand saw is forA hand saw is a flat blade with teeth along one edge, used to cut wood by hand rather than with a power tool. It is the right choice for a single straight cut through timber, like shortening a batten or cutting a piece of wood to length. For lots of repeat cuts or very thick timber, a power saw is faster, but a hand saw gives you more control while you are learning.

HN-02Pick the right saw for the jobA panel saw is the long, general-purpose saw most toolkits have, good for cutting boards and battens. A tenon saw is shorter and stiffer with a reinforced top edge, better for smaller, more precise cuts like trimming a piece of moulding. For a first attempt, use whichever you have, but a tenon saw is easier to control if you own one.

HN-03Mark your line before you cutUse a pencil and a try square (an L-shaped tool that gives you a perfect right angle) to draw a clear line across the wood where you want to cut. Beginners often skip this and eyeball it, then wonder why the cut ends up wonky. Mark both the top face and the edge if you can, so you have a line to follow from more than one angle.

HN-04Secure the wood so it cannot moveClamp the wood to a workbench or hold it firmly in a vice, with the cutting line hanging just past the edge of the support. If the wood can wobble or slide, the saw will wander off your line and the cut will be ragged. Keep your free hand well away from the line of the saw at all times.

HN-05Start the cut with short, gentle strokesRest the saw teeth on the waste side of your line, then draw the saw backwards two or three times to score a shallow groove. Use your thumb knuckle against the blade to guide it steady while you do this, but only until the groove is started. Beginners often push hard straightaway, which makes the blade skip and jump off the line.

HN-06Saw with long, even strokesOnce the groove is established, use the full length of the blade with long, smooth push-and-pull strokes, keeping the saw upright and following your marked line. Let the saw's own weight and the teeth do the cutting; do not force it or lean on it. Aim for a steady rhythm rather than speed, and check the line every few strokes to make sure you are still on track.

HN-07Check the cut is straight and squareWhen you have cut through, hold the try square against the cut end to see if it sits flush all the way round with no gaps. Run your finger along the cut edge to feel for any big wobbles or curves. A good cut looks like one clean line, not a wavy one; if it has drifted, you can true it up slightly with light strokes of the saw or a rub with sandpaper.

HN-08Know the mistake most beginners makeThe most common fault is letting the saw tilt sideways as you cut, so the cut angles inward instead of staying vertical through the wood. Stop every few strokes and check the saw is upright, not leaning towards or away from you. If a cut has gone wrong, it is easier to start again on a fresh piece than to force the same cut straight.
