Shave Hooks: Stripping Paint from Mouldings and Architraves Safely
UK guide to shave hooks for paint stripping. Triangular vs pear vs combination blades, safe technique with heat guns, and the lead paint warning for pre-1970 homes.
A flat paint scraper turns a round moulding into a row of gouges within ten seconds. The blade is straight, the timber isn't, and the edges dig in where the profile curves away. A shave hook has a shaped blade that follows the moulding profile instead of fighting it. Every Victorian skirting and Edwardian architrave in the country has been stripped with one for the last century.
What it is and when you need one
A shave hook is a small hand tool with a shaped steel blade on a short handle. You heat old paint with a heat gun or an infrared stripper until it bubbles and lifts, then pull the shave hook along the surface. The blade slides under the softened paint and peels it off in sheets or curls.
The point of the shaped blade is contact. On a flat door panel a straight scraper works fine. On a moulded skirting, an ogee architrave, a turned staircase baluster, or a panelled door, a straight blade only touches the high points. Everywhere else the paint stays put. A shave hook blade is cut to match common profiles so it rides in the shape and lifts paint from the full surface in one pass.
You need one whenever you're stripping paint from profiled woodwork. That includes repainting old skirting that has thirty years of build-up on it, taking a painted banister back to bare timber before staining, rescuing an architrave the previous owner painted gloss white over ten older coats, and preparing panelled doors for repainting. If a room has any original period woodwork and you want a clean finish, a shave hook is the tool that gets you there.
Blade profiles
Three blade shapes cover almost every job. Most UK retailers stock all three, and a combination blade packs multiple profiles onto a single tool.
| Profile | Shape | Best for |
|---|---|---|
| Triangular | Three flat edges meeting at sharp points | Flat sections, wide shallow curves, convex mouldings, door panels, window rails. The sharp points get into internal corners where a curved blade can't reach |
| Pear-shaped | Rounded teardrop outline | Tight concave mouldings, ogee profiles, round beading, staircase balusters. The curve rides inside concave shapes that a triangular blade would bridge across |
| Combination (3-in-1) | One blade with triangular, pear, and convex edges | General DIY. Covers nearly every profile on a Victorian or Edwardian skirting or architrave. The right choice if you're buying one tool |
Professional decorators often carry both a triangular and a pear-shaped shave hook and swap between them. For a homeowner stripping one room of skirting and architrave, a combination blade does the job. It's a little slower in places because you're turning the tool to find the right edge, but you only buy one tool.
Blades come in stainless or carbon steel. Stainless is standard on modern decorator tools and resists rust if you leave the tool damp. Carbon steel holds a slightly better edge but demands more care. Either is fine for home use.
How to use it safely
The tool is simple. The technique is about heat control and direction.
Prepare the work area
Lay dust sheets on the floor and tape them to the skirting edge so flakes don't slide underneath. Open one window for ventilation, but avoid cross-drafts that blow debris around the room. Keep a metal bucket nearby for scraped paint. Not plastic: hot paint flakes can melt plastic or ignite residue. A galvanised bucket or an old paint kettle works.
Heat the paint
Aim the heat gun or infrared stripper at a section roughly the width of the shave hook blade. Keep the heat source moving in small circles. Wait until the paint starts to bubble, soften, and lift from the substrate. With a heat gun this is usually 10-30 seconds. An infrared stripper takes 30-90 seconds but heats the paint more evenly through its full depth.
Pull, never push
Place the shave hook at one end of the heated section, press it firmly against the moulding so the blade profile matches the shape, and pull the tool toward you with steady pressure. The softened paint comes off in a curl or sheet. Never push. Pushing loses control, skates the blade over the timber, and is the quickest route to a gouged moulding or scraped knuckles.
Work with the grain on timber. Going across the grain tears the surface fibres and leaves more sanding than you want later.
Work in small sections
Strip patches of 150-300 mm at a time. Heat a section, scrape it, move on. Trying to heat a whole wall's worth of skirting at once means the first bit cools before you get to it, and the last bit scorches while you're stripping the first.
Drop debris into the bucket
As each sheet or curl lifts, flick it off the blade into the metal bucket. Empty the bucket outside at the end of the session, once the debris has cooled. Hot paint dumped on compost or into a plastic bin can smoulder for hours.
Lead paint warning
If your property was built before 1970, assume the paint contains lead until a test proves otherwise.
Lead was phased out of UK domestic paint through the 1960s and banned entirely in 1992. Any house that still has its original woodwork may have leaded paint under later decorative layers. Lead paint is harmless while it sits on the wall. Heat changes everything.
Lead vaporises at roughly 370°C. A typical heat gun runs at 450-600°C. Pointing a heat gun at leaded paint releases lead fumes that are invisible, odourless, and cause permanent neurological damage. Children and pregnant women are at highest risk because lead affects developing brains.
What to do instead:
-
Test before you strip. 3M LeadCheck swabs (or equivalent home lead test kits) cost
at Screwfix, Toolstation, or Amazon UK. Rub a swab on the paint. It turns pink or red if lead is present. Test every colour layer you can see, not just the top coat. Older layers are more likely to contain lead.Lead paint test swabs (3M LeadCheck or equivalent home kit)
£10 – £15
-
Use an infrared paint stripper, not a heat gun. An infrared stripper runs at 200-400°C (below the lead vaporisation point), heats paint from the substrate up, and lifts multiple layers at once. Units like the Speedheater, Spengar, or Eco-Strip Cobra cost
new but are available to rent from larger hire shops. For a one-off room, renting is cheaper than replacing your lungs.Infrared paint stripper unit, new (Speedheater, Spengar, Eco-Strip Cobra)

Wear a P3 (FFP3) filtered respirator, not a dust mask. FFP3 disposables from Screwfix cost
each. Add safety glasses. Wear old clothes you can wash separately or bin.FFP3 disposable respirator mask (each)
£3 – £4
-
Contain the debris. Dust sheets taped to the skirting edge. Damp-wipe the room at the end of each session. Never dry-sweep leaded flakes: they become airborne.
-
Keep children and pets out during stripping and for 24 hours after. Wash hands and face thoroughly before eating, drinking, or smoking.
For large areas of leaded paint, consider hiring a contractor with lead-safe certification instead of attempting it yourself.
Heat gun pairing
A shave hook on its own does nothing. Cold paint shrugs off even a sharp blade. The tool only works with a paired heat source.
For post-1970 properties (no lead risk), a standard heat gun is fine. Decent 2000W heat guns cost

£25 – £40
For pre-1970 properties, pair the shave hook with an infrared paint stripper. Slower, more expensive, harder to find, but it keeps lead fumes out of the air. Hiring a unit for a weekend is often enough for a single room.
Chemical strippers are a third option. Cold, so no vaporisation risk, and products like Peel-Away are commonly used on listed buildings. Messier and slower than heat, and still need a shave hook to lift the softened paint.
What to buy
Shave hooks are cheap tools. Even the premium options cost less than a takeaway.
| Tier | Price | Examples | Buy if... |
|---|---|---|---|
| Budget fixed-blade | £4-8 | Harris, Amtech, Silverline, Faithfull Soft-Grip Triangular, Prodec (Toolstation), Fortress (Screwfix) | You're stripping one room of skirting or one door. The blade isn't replaceable, so when it's blunt you buy a new tool, but at £5 that's acceptable for occasional use |
| Mid replaceable-blade | £10-20 | Stanley Professional Combination Shavehook (STA028824), Stanley Dynagrip 0-28-659, Bahco 650 range | You're doing a full renovation with multiple rooms of woodwork. Replaceable blades cost £4-6 for a pack of three, so you keep the handle and refresh the edge as needed. The Stanley Professional is the decorator's default |
| Premium | £20-30 | Specialist decorator brands, carbide-edged professional models | You're a trade buyer stripping paint weekly. For a one-off renovation the mid tier is already more than enough |
If you only buy one, make it a combination blade. Triangular-only and pear-only tools are cheaper but you'll regret the gap the first time you meet a moulding the blade doesn't fit.
Care and blade maintenance
A sharp blade is safer than a dull one. You press harder on a dull blade, which means you slip more often, which means gouges and cut fingers.
Sharpen the blade with a fine flat file. File the flat (non-bevelled) side of the blade, using a few light strokes in one direction. Do not file the bevelled side: the factory angle is correct and filing it changes the geometry. A few strokes after every session keeps the edge keen.
Wipe the blade clean and dry after use. Paint residue plus moisture equals rust. A drop of WD-40 or light machine oil on the blade before storage protects the steel. Store the tool flat in a decorator's box or tool drawer, not loose in a damp shed.
On replaceable-blade models, swap the blade when it no longer holds an edge after sharpening. Spare blade packs cost a few pounds. Fighting a dull tool is slower and more dangerous than changing a blade.
On fixed-blade tools the whole tool is replaced once the blade is done. At
