The best long-handled crack weeders, compared.
Top pick: Anwor patio weeder set (3 Weeder Tools) Best value: Anwor patio weeder set (3 Weeder Tools) – About £16.99 for a stated 150 cm, £3 less than the other Anwor set, with heads pre-fitted and 4.3 from 154 reviews. Updated October 2026.
A long-handled crack weeder is a standing blade or narrow brush for weeds and moss in patio and paving joints, so you do not have to kneel. In the UK the proper version is a block-paving knife on a handle of about 1.4–1.6 m, or a wire brush on a similar pole. The Royal Horticultural Society treats those as two jobs: the knife severs and levers growth in the crack, and the angled wire brush scrubs moss, seedlings and debris. A useful tool has a head thin enough for a narrow block joint and a pole you can lean on without it folding. A scrape clears the growth you can see. It does not pull a taproot for good, and on unbound block paving the joint still needs kiln-dried sand brushed back in once the crack is empty. Length, head and bristle are in the [long-handled crack weeder buying guide](/hub/weed-control/long-handled-crack-weeder/sub/long-handled-crack-weeder-buying-guide).

Personal buying guide
Question 1 of 2
What must the listing state?
The Anwor 3 Weeder Tools set is the same four-section idea at £16.99, listed at 12 x 7 x 150 cm and 17–60 inches, and it weighs 900 g. On amazon.co.uk it is 4.3 from 154 reviews. The L-scraper and the U-scraper arrive fitted to a pole section, and the bullets include hanging holes so the pieces can hang once split. One UK review wants a sharper, thinner blade because narrow cracks are difficult, and another says the angled weeder works and the brush less so. A review says not to buy it if you have arthritis, because the bolt is a nightmare to undo with the supplied tools. Several reviews mention the back, which is both the reason to stand and a sign the angle is not free. Among these four listings it is the best value when you want a stated 150 cm under £20 and you will use the brush on concrete joints.
Pros
Cons
Best for: You have a concrete patio or block paving, you can stand, and a bolt is still manageable.
Less suitable: The joint is a hairline of about 2–5 mm that needs a slim knife, or your hands cannot undo the bolt.
Specifications
Common questions
How is this Anwor set different from WRTAH01?
Both list 12 x 7 x 150 cm and a four-section handle from 17 to 60 inches. This one is £16.99, weighs 900 g, and the bullets say the L and U scrapers arrive already fitted to a pole section, with hanging holes.
Will the blade fit a narrow crack?
One UK review says it would be better with a sharper, thinner blade because narrow cracks are difficult. Another says the angled weeder works and the brush less so.
Is the head bolt easy to undo?
A UK review says not to buy it if you have arthritis, because the bolt is a nightmare to undo with the supplied tools.
The Anwor WRTAH01 is a hand-powered brass-brush and scraper set at £19.99, listed at 4.2 from 466 amazon.co.uk reviews. The page gives 12 x 7 x 150 cm, and the bullets say the four stainless sections run from 17 inches to 60 inches. Reviewers say the blades get between blocks, and some say the long handle sits at the wrong angle, so the head is easier in the hand than on the full pole. UK reviews say an Allen key swaps the three heads, and that the change is a faff, although the bullets call it quick. The listing asks whether it removes moss and does not answer; the U-scraper is described for mossy pavements, and some reviews mention moss. At 840 g it is the same class of tool as the £16.99 Anwor set, with more reviews and no hanging hole stated. In this set it is the top pick when you want that larger review file on a stated 150 cm pole. It is not a slim knife for a joint of about 2–5 mm.
Pros
Cons
Best for: You want a stated 150 cm set and the larger UK review file, for concrete blocks rather than a hairline knife cut.
Less suitable: Your hands cannot work an Allen key, or the joint is about 2–5 mm and needs a slim one-piece paving knife.
Specifications
Common questions
How long is the Anwor WRTAH01 handle?
The listing dimensions are 12 x 7 x 150 cm. The bullets say the four stainless sections adjust from 17 inches to 60 inches.
Can you change the heads without tools?
The bullets say the three heads install and swap quickly. UK reviews say you need an Allen key, and that the change is a faff.
Does the moss question on the listing get an answer?
The listing asks whether it can remove moss and does not answer. The U-scraper is described for mossy pavements, and some UK reviews mention moss.
The ADLUH set is an L-shaped scraper and two brush heads at £11.99, listed at 4.0 from 117 amazon.co.uk reviews, and it weighs 600 g. The page gives a packed size of 43 x 15 x 5 cm and does not state an assembled standing length. UK reviews say the brush gets into block-paving gaps and that the scraper is the head for wider gaps, where the blade is also called difficult and the bristles can bend. One review says the extra poles mean you need not bend. Others say the blade loosens in use, the crevice tool bent on first use, or the set broke on first use, while one review says the screw joints stay tight. It is the lower shelf price in this set if the brush is the head you will use on concrete. It is the wrong buy when you need a published length near 150 cm, or a scraper you can lean on.
Pros
Cons
Best for: You want the lowest serious price in this set and you will use the brush on concrete blocks.
Less suitable: You need a published reach before you buy, or a blade that stays tight on the first hard joint.
Specifications
Common questions
How long is the ADLUH handle?
The listing gives packed dimensions of 43 x 15 x 5 cm and does not state an assembled length. The title says the handle is adjustable, and one UK review says the extra poles mean you need not bend.
Which head fits a narrow block-paving gap?
UK reviews say the brush gets into block-paving gaps and that the other tool is for wider gaps. The blade is also described as difficult in narrow cracks, and the bristles can bend.
Does the blade stay tight?
One review says the screw joints stay tight. Others say the blade loosens in use, the crevice tool bent on first use, or the set broke on first use.
The GREELIX GL-FFX-01 is two copper-plated V-brushes and one scraper on four stainless sections, at £10.99 and 3.8 from 123 amazon.co.uk reviews, listed at 1.29 kg. The technical table prints 1 x 1 x 1 cm, which is not a usable length, and the bullets say the scraper can connect only three of the four poles. UK reviews call the extensions thin or bendy, say a head stayed wobbly when tightened, and report heads or poles that arrived broken or broke after one use. One review says it works if you do not put too much pressure on the handle. Reviews say the brush works in thin joints and that the scraper does not, because it has no sharp point. Many reviews mention the back and the knees, which a standing pole is meant to spare and a bendy pole does not. It is the cheapest file here, and the missing length plus the thin poles are why it is not the set to lean on.
Pros
Cons
Best for: You want a cheap brush-led try on hard concrete and you will keep your weight off the pole.
Less suitable: You will lean hard on the handle, or you need a stated standing length on the listing before you buy.
Specifications
Common questions
What is the real length of the GREELIX set?
The technical table lists 1 x 1 x 1 cm, which is not a usable assembled length. The bullets describe four stainless sections and say the scraper can connect three poles only. No centimetre reach is stated.
Will the poles take a hard lean?
UK reviews call the extensions thin or bendy, say a head stayed wobbly when tightened, and report heads or poles that arrived broken or broke after one use. One review says it works if you do not put too much pressure on the handle.
Which head is for a thin slab gap?
Reviews say the brush works in thin joints and that the other tool does not, because it has no sharp point. The listing claims both heads for block paving, patios, driveways and paths.
Shelf date 19 October 2026. The scores use the four amazon.co.uk listings kept in this set and the review notes already in the display fields. This is not a lab test. A packed size is not scored as a standing length. The GREELIX line of 1 x 1 x 1 cm is not scored as a reach. The highest score is the top pick. The lowest shelf price among sets with a stated length near 150 cm is best value. One of each. A slim one-piece paving knife is outside this Amazon set, so it cannot take a badge here.
Amazon evidence
30%Star rating on amazon.co.uk, with more weight when the count is in the hundreds and the texts are for that ASIN. A 4.2 from 466 outranks a 4.3 from 154 when the kits are the same class.
Listing fit
30%A stated length near 150 cm scores. A brass or copper-plated brush plus a scraper scores for concrete joints. A packed size with no assembled length does not score as a standing tool.
Review outcome
25%Heads that reviewers say enter a block joint score. A pole or blade that bends, snaps, or unscrews is deducted. An Allen key or a stiff bolt is a smaller deduction.
Value
15%Shelf price in GBP against a tool with a stated reach. A lower price does not win this block when the length is missing or the reviews describe a first-use break. That block decides the separate value badge, not a tie on the headline score.
Buy the head and the stated length before you count pieces in the box. A long-handled crack weeder is a standing knife or a narrow brush for a paving joint, so you do not kneel. Concrete block joints are often about 2–5 mm, and a thick scraper often misses them. A packed size is not a reach. The GREELIX line of 1 x 1 x 1 cm is not a length. Brass or copper-plated wire is for hard concrete, not Indian sandstone. On unbound block paving, plan to put kiln-dried sand back on a dry day.
A long-handled crack weeder is a standing blade or narrow brush for weeds and moss in patio and paving joints, so you do not have to kneel. In the UK the proper version is a block-paving knife on a handle of about 1.4–1.6 m, or a V-shaped wire brush on a similar pole. The RHS treats those as two jobs. The knife severs and levers growth in the crack. The angled wire brush scrubs moss, seedlings and debris. A scrape does not remove a taproot for good.
A claw stand-up weeder, a hoe and a spinning electric brush were a different product. The kept set is a manual multi-head pole with a brush and a scraper. Counting heads does not tell you which head enters a 2–5 mm joint.
ADLUH states 43 x 15 x 5 cm packed. GREELIX lists 1 x 1 x 1 cm. Neither is an assembled standing length. The two Anwor listings are the ones that state 150 cm. They are separate ASINs.
On unbound block paving the jointing sand is part of the structure. Scraping and pressure washing empty it. Kiln-dried sand, on a dry day, is the refill the paving guides name. Do not rout out a resin or polymeric joint, and do not use a wire brush on Indian sandstone.
Head shape is the first check, because the joint width decides which head can enter. Concrete block joints are often described as about 2–5 mm. A slim 90 degree knife enters that gap. A thick L-scraper often does not. That is what UK reviews say about the ADLUH and GREELIX scrapers. The brush is the head those reviews keep using in block gaps. The scraper is described for wider gaps, or as a head with no sharp point.
Published standing length is the second check. Burgon & Ball states 150 cm. DeWit via Crocus is 140 cm. Kent & Stowe via a retailer is 1.59 m. The two Anwor listings state 150 cm, and the bullets say the four stainless sections adjust from 17 inches to 60 inches. They are separate ASINs. WRTAH01 weighs 840 g. The 3 Weeder Tools set weighs 900 g, and the L and U scrapers arrive fitted to a pole section. ADLUH only gives a packed size of 43 x 15 x 5 cm. That is not an assembled length.
Three typical situations, each with a recommendation from this comparison.
You have a concrete drive or patio and you want a published length before you buy. The Anwor WRTAH01 is the top pick at about £19.99, with 150 cm listed and 4.2 from 466 reviews. On unbound blocks, plan to brush kiln-dried sand back into a dry joint after you scrape.
You want a stated 150 cm and you would rather not start with an Allen key. The Anwor 3 Weeder Tools set is best value at about £16.99, with the L and U scrapers already on pole sections. One UK review says the bolt is hard to undo with arthritis.
You will use the brush in block gaps and you can accept that no standing length is stated. The ADLUH set is about £11.99, and UK reviews use that brush in the gaps. Several reviews also describe a bend, a snap, or a blade that loosens.
The top pick is the Anwor WRTAH01 at about £19.99. It scores 88, the highest here: a stated 150 cm, a brass brush plus L and U scrapers, and 4.2 from 466 reviews. UK reviews say an Allen key swaps the heads, and the angle can miss the joint. Best value is the Anwor 3 Weeder Tools set at about £16.99. It is the same class of stated 150 cm, £3 less, with the heads pre-fitted and 4.3 from 154 reviews. A thin-blade complaint and a stiff bolt are the deductions. ADLUH and GREELIX are cheaper and do not state a standing length.
