Choosing wood carving tools
The list above is what exists. This is how to decide which of it you actually need, what separates a tool worth keeping from one that ends up at the back of a drawer.
Three crafts, different tools
Whittling is done in the hand with a knife, no bench and no mallet. Relief and sculptural carving is done on a held workpiece with gouges, driven by hand for fine work and a mallet for waste removal. Chip carving is a single knife making paired angled cuts that release a triangular chip.
Buying a 12 piece gouge set for whittling wastes most of it, and a whittling knife will not hollow a bowl. Decide the craft first and the tool list follows from it, which is the opposite of how most starter sets are sold.
- Whittling
- One or two knives, in the hand, no bench. The cheapest way into carving by a wide margin.
- Relief carving
- Gouges and a V tool on a clamped panel. Depth and shadow rather than shape in the round.
- Sculptural
- Larger gouges and a mallet, plus rasps and rifflers to refine. Waste removal is most of the work.
- Chip carving
- One knife, geometric layout, and a level of sharpness the other three tolerate being without.
Reading gouge numbers
Carving gouges are described by sweep and width. The sweep number is how curved the cutting edge is: a number 3 is nearly flat, a number 9 is a deep U, and a number 11 is a veiner that cuts a narrow channel. The width is the edge in millimetres.
The V tool is numbered separately, usually 12, and is defined by its angle rather than a sweep. It cuts a groove with two flat walls, which is what outlines a shape before any waste is taken out around it.
- Low number, flat
- A 3 or a 5 smooths and shapes. Most of the finishing cuts in relief work happen here.
- High number, deep
- A 9 or an 11 removes wood fast and leaves a deep scoop. Roughing rather than finishing.
- The V tool
- Outlines. A crisp V groove around a shape is what lets you cut down to it cleanly.
- Width in millimetres
- The second number. A 5/12 is a moderate sweep, 12mm wide.
Grain direction decides the cut
Cutting with the grain, the fibres are severed and supported and the surface comes off glassy. Cutting against it, the blade lifts the fibres ahead of the edge and they tear out below the surface you wanted. The tear does not show until you are past it.
So carving is constantly rotating the work or changing which direction you cut from, rather than working steadily around a shape. On a curved form the grain direction changes every few degrees, which is why carvers turn the piece more often than they change tools.
- Downhill, always
- Cut with the fibres running away from the edge. Uphill tears out below the surface.
- Turn the work
- Not the tool. On a curve the right direction changes every few degrees.
- Stop cuts first
- A V groove or a knife cut across the grain gives the fibres somewhere to break off.
- Shallow across end grain
- End grain crumbles under a deep cut. Take it in light passes with a very sharp edge.
Sharpening is half the craft
A carving edge has to sever fibres cleanly with hand pressure alone. There is no motor and no weight behind it, so anything less than genuinely sharp crushes the wood, and the crushed surface will not take a finish evenly.
Carving gouges are also curved, which means a flat stone only touches part of the edge. That is what slip stones and shaped strops are for, and it is why most beginners' first real problem is not technique but an edge that was never properly sharp.
- Sharper than a chisel
- No mallet and no weight behind it, so the edge alone has to sever the fibre.
- Strop constantly
- Every few minutes, not at the end of the day. It is seconds and it keeps the edge from ever going.
- Shaped stones
- A flat stone touches one point of a curved edge. Slips and cones match the sweep.
- Inside and out
- A gouge has an inner bevel too. Ignoring it leaves a wire edge that folds on first contact.
Holding the work and your hands
Carving injuries are almost all the same injury: the tool leaves the wood faster than expected and the other hand is in front of it. So the rule is that no part of you is ever on the far side of the cut, and the work is held by something other than a hand where possible.
Whittling is the exception, because the work is in the hand by definition. There the answer is a cut resistant glove on the holding hand, a thumb guard, and cuts that move away from the body rather than toward it.
- Nothing beyond the edge
- The single rule. Almost every carving cut injures the hand that was holding the work.
- Clamp or a carver's screw
- Frees both hands, which also makes the carving better rather than only safer.
- Glove for whittling
- The holding hand cannot leave the work, so it wears the protection instead.
- Two hands on the gouge
- One pushing, one guiding and braking. That is what stops an overrun.
Frequently asked questions
- What tools do I need to start wood carving?
- It depends which carving. Whittling needs one good knife, a strop and a cut resistant glove, which is a very cheap start. Relief carving needs a number 3 and a number 9 gouge, a V tool, a mallet, a way to clamp the work and sharpening kit.
- What do the numbers on carving gouges mean?
- The first number is the sweep, meaning how curved the edge is: a 3 is nearly flat, a 9 is a deep U, an 11 is a narrow veiner, and 12 is the V tool. The second number is the width of the edge in millimetres, so a 5/12 is a moderate sweep 12mm wide.
- What is the difference between whittling and carving?
- Whittling is done in the hand with a knife and no bench, so the piece is small enough to hold. Carving usually means gouges on a workpiece held by a clamp or a carver's screw, often with a mallet. They share the need for sharp edges and almost no tools.
- What wood is best for carving?
- Lime, also sold as basswood, for almost everything: even textured, soft enough to cut cleanly, and it holds detail. Butternut and jelutong are similar. Avoid pine to start with, since it is soft but the hard grain lines and soft summer wood cut at completely different rates.
- How sharp do carving tools need to be?
- Sharper than a bench chisel, because there is no mallet or body weight behind the cut. Hand pressure alone has to sever the fibres, and anything less crushes them, which leaves a fuzzy surface that will not take a finish evenly. Strop every few minutes.
- How do I sharpen a curved carving gouge?
- A flat stone only touches one point of a curved edge, so you need shaped slip stones or a cone that matches the sweep, plus a shaped strop. The inner bevel matters too: ignoring it leaves a wire edge that folds over on the first contact with wood.
- Why is my carving tearing the wood instead of cutting it?
- Either the edge is dull, which crushes fibres rather than severing them, or you are cutting against the grain so the blade lifts the fibres ahead of it. On a curved shape the grain direction changes constantly, which is why carvers turn the work rather than the tool.
- Do I need a mallet for wood carving?
- For relief and sculptural work, yes: waste removal by hand pressure alone is slow and tiring. A round carver's mallet lets you strike from any angle without turning your wrist. Whittling and chip carving use hand pressure only and never need one.
