Carving Greek Acanthus Leaf 10

The last move of an undercut is a pull, not a push. Catch the loosened waste on the very corner of a blade, make a few tiny movements with your fingers rather than your arm, then draw the chip out from below. I call it hooking. Push instead and you drive the waste deeper into a space you can no longer reach.

Most wood carvers never learn this, and I want to be straight with you about why. Leaving a panel flat on its ground is faster. You cannot break a gouge doing nothing. Sometimes the undercutting eats more hours than roughing out the whole design did, and at the end of it the shape on top has not changed at all.

Everything you see has changed. Today the Greek acanthus finally gets some air underneath it, and that is the part a photograph never quite shows.

What this last stage is really about

• Pull the chip, never shove it.
• A bent tool gets beneath an edge while its handle stays clear of the carving above, and that one piece of geometry is why back bents live permanently at the front of my rack.
• Small tools do the last quarter.
• Edges get refined at the very end, after nothing else will disturb them.
• A stuck chip means recut, not force.
• Every one of these moves depends on an edge so sharp it hisses, which is why my old teacher refused to let me blame the wood for anything.

What is hooking in wood carving?

Waste caught on the corner of an edge, then drawn outward. Your hand barely moves. Little micro movements with the tip of the blade, working the chip loose from the space under the leaf until it will come away, and then it comes away cleanly in one piece. Nothing is levered, and nothing whatsoever gets forced.

Where does the word hoiking come from?

England, where they have used the older word for longer than anybody can document. Carvers there have a specific term for this technique and it lands on my ear as hoiking, which I rather like, because it sounds exactly like what the tool does. Words for craft moves travel badly between countries. The motion does not.

Why do so many carvers skip undercutting?

Difficulty, plainly. Nobody should fool themselves that this is the easy half of relief work. Tools break. Carvings break. Getting a genuinely good undercut around a whole panel takes a long evening, and every minute of it carries a risk that a finished lobe leaves on the floor. Leaving the piece flat carries none of that risk.

It also leaves you with a carving nobody looks at twice.

Which tool hooks best?

Whichever one can already reach the chip. My number 7 hooks. A small number 5 straight gouge hooks. The knife hooks beautifully and gets into pockets no gouge will enter. What matters is working on the corner rather than the middle, and travelling toward yourself in very small increments.

What are sideways undercutting tools?

Blades that turn the edge ninety degrees so it faces along the surface instead of into it. Chris Pye designed a set and Ashley Iles make them. Three in all, and they come as a right hand, a left hand and one that runs straight. When I first got mine those three were the only tools I touched for undercutting, for months. Now they come out for the awkward spots only.

Worth owning if undercutting is going to be your habit. Not worth owning as a first purchase, and there are cheaper ways to learn the same reach.

How small do these tools get?

Very. My smallest is a short bent number 9 at 2 millimetres, three thirty seconds of an inch, and beside it sits a gouge from The Dockyard, one eighth wide, which goes down a pipe nothing else will enter. A short bent 3A at the same width does the cleanup afterwards. Tiniest thing on the bench today is a bent gouge number 7 by Ashley Iles, two millimetres across, and it reaches places I would have called impossible.

A tiny straight gouge will do most of the same work. What it will not do is reach as deep, which is the one thing the bent shape is for.

Is there such a thing as bad wood?

My teacher had one answer to that, and he gave it to me every single time I complained. There is no such thing as bad wood. Only dull tools. I was young and I thought he was being hard on me. Four decades later I have never once found an exception, and it is probably the most important sentence anybody ever said to me at a bench.

Your tools must be sharp. Absolutely must. Everything else in this lesson assumes it, and sharpening is where that gets fixed for good.

Does an expensive knife carve better?

Mine is cheap and it does the main work on this panel. I reach for it constantly, on every project, because it gets deep into places that are impossible with anything else in the rack. Price is not the variable. A strop and two minutes turn a cheap blade into a good one.

What happens when a chip gets stuck?

Recut. A chip that will not lift is still joined to the wood somewhere you cannot see, and levering it is how a finished edge breaks off in your fingers. Go back over the same line, one more pass, and then the piece flies out on its own. Easy. Forcing that same chip costs you an edge you cannot put back.

Nobody needs to call this patience. Going slowly is simply the cheaper of the two options.

Can you press too hard when carving a pipe?

Very easily, and the damage does not look like damage at first. Lean into the wall of a pipe and the fibres crush rather than part, so the surface goes woolly and no amount of later work brings the crispness back. Carry the shadow in gently, from the open side, and accept that a few tight spots will never take a deep undercut at all.

Knowing when to stop is a skill. Overdoing an undercut in a corner that cannot carry it wrecks more panels than timidity ever has.

When do you clean up the outlines?

Last, and this surprises people. Every edge on this panel is going to get knocked about by the tools going underneath it, so refining them now means refining them twice. My outlines look rough all through this lesson on purpose. Once the undercutting is done and the background drops, I come round with the point of the knife and make every line crisp in one pass.

How far down does the space under a leaf go?

Down to the same level as the background, wherever the design allows it. Picture the floor of the panel continuing straight on underneath the leaf, and carve toward that. There is still another eighth of an inch, 3 millimetres or so, to come off this relief when the ground drops later, and every bit of that will deepen the shade again.

The small tools, and what each one is for

Tool	Where it goes	Note
Back bent 25, 13 mm	Under any free edge with room to swing	Deepest
Small back bent	Right beside a finished rim	Reverse curve keeps the shaft off the work above it
Bent gouge 7, 2 mm	Pockets	Smallest thing on the bench, and it still gets right under a rim
Short bent 9, 2 mm	Slivers	Anywhere a normal shaft would bruise the neighbour
Dockyard, an eighth	Down a pipe where nothing wider will go	Gentle
Short bent 3A	Cleaning the floor a bent tool leaves behind	Flat enough that you can see what it did
Sideways set	Awkward spots	Three of them, one for each hand and a straight
Cheap knife	Everywhere else	Nothing reaches further and nothing costs less

Why does a carver keep swapping tools every thirty seconds?

Several roads lead to the same undercut, and none of them is the official one. Try them all on scrap and keep whatever suits your hands. Mine settled on the back bent used on its corner, because for me it is the quickest and the most accurate of the lot, and a technique that is quick for me might feel clumsy to you. Watch the result, not the brand of the handle.

Anybody who tells you there is one correct tool for this has not undercut enough limewood.

Can a plain straight gouge undercut anything?

Where you can come in from the edge of the board, yes, and safely. Come in past the outer edge of the board and a normal number 7 slides beneath a leaf with nothing in its way. The trouble starts in the middle of a design, where a straight shaft has to rest on carving you already finished. Bent tools exist for that one problem and no other.

Does the V tool ever beat the bent tools?

On this panel it did, in one spot, and it surprised me. I had the back bent in my hand, could not get the depth I wanted, picked up the V tool almost as an afterthought and it went further under than anything else had managed. Still being corrected by the wood twice a session, at my age. Keep the whole rack within reach and let the shape decide.

I also went too deep in one place today, and I said so out loud while it was happening rather than editing the moment out. One area beside the big cluster still looks wrong to me. I will fix it, and you will watch me fix it, because a lesson that only shows the passes that worked teaches nobody anything. The techniques library has the repairs.

How long should undercutting take?

Longer than you think, and often longer than establishing the main form did. Discouraging, maybe. It should not be, because those are the hours that actually show. Shaping alone gives you a good drawing in wood. Work underneath gives you something that changes as a person walks past.

Light them properly and the shadows are gorgeous. No other part of relief work pays back like this one does.

What does good lighting do to a finished undercut?

Everything. A panel that looks ordinary under a ceiling bulb comes alive the moment light rakes across it from one side, because every band of shade you spent the evening carving suddenly has somewhere to fall. Hang your work where a window catches it sideways and you will see the difference from the doorway. That is how these reliefs were meant to be seen, and it is how churches lit them for four hundred years.

Ceiling light straight down flattens all of it. Same carving, half the work visible. Lesson eight made that point about your own bench lamp while the carving was still being shaped, and it applies twice as hard now. Go and look at the sculpture galleries in any serious museum and watch how carefully the lights are aimed.

Does the grain still matter this late on?

More than ever, and the consequences are worse now. Half a panel of finished carving sits between your tool and the floor, so a run that goes wrong takes a completed lobe with it. Read which way the fibres travel before every approach, and when the grain runs against you, walk round the bench instead of pushing through.

Where does the panel stand now?

Undercut nearly everywhere, outlines still rough, background still high. Lesson nine opened the shadows and gave you the back bent. This one finished them and named the move. What comes next is dropping the ground and refining every edge, and after that the leaf you have been staring at for ten lessons finally looks like the thing in the photograph.

A Byzantine leaf takes the same technique further, and the Roman one asks for less of it. Every school of ornament decided separately how much air it wanted behind a leaf, and you can date a carving by that decision alone.

What would I tell a beginner starting their first undercut?

Pick one edge. Just one, on a piece you would not cry over. Take four light passes with whatever bent tool you own, hook the waste out, and then set the board on a windowsill and look at it in daylight. That one edge teaches more than an hour of watching me. The drawing lesson built everything above the shadow, and design explains why the shadow belongs where it does.

Sharpen everything. Hook, do not shove. Leave your outlines rough until the very end, and go look at a Gibbons swag in person if you ever get the chance, because photographs cannot show you what the air behind a carving does. The rest of this course, and the tools course that explains every number in that table, sit behind one door. Shall we carve?
