Drainage spade buying guide
Updated: 21 October 2026
You need a slot for a drain, a pipe or a fence post, and a border spade would move too much soil. A drainage spade is the long narrow blade for that slot. This page covers pattern, width, lift, tread, shaft and weight. On the eight amazon.co.uk listings in our [drainage spade comparison](/hub/digging-tools/drainage-spade), captured shelf prices run from £11.54 to £44.99, not a market average. The shortlist is the [best drainage spade](/hub/digging-tools/drainage-spade/sub/drainage-spade-best) page. Peter F. compared the listings and public UK sources in October 2026. There was no lab test. A qualifying purchase can earn a commission at no extra cost to you.

What a drainage spade is for
A drainage spade, often sold as a draining shovel, cuts a deep slim channel for a land drain, a pipe, a cable or a straight-sided post hole. It is a poor tool for gravel or for mixing, because the blade will not carry a wide load. Spear & Jackson’s shovel selection guide keeps that draining pattern apart from a square-mouth shovel, a general trenching shovel, a cable-laying shovel and a grafting shovel. You start with the hole, then the name on the label.
A Newcastle-style drainer is the UK trade name for a long narrow head, often with a little lift so a bite of soil stays on the blade. Masseys DIY describes one Spear & Jackson Newcastle, the 2153AE, with a 405 by 105 mm head and 55 mm of lift on a 711 mm shaft. That is a different model from the 2154HK in our comparison, which is why 16 inch is not one blade. Cable-laying shovels are slimmer, with a rounder nose. Grafting spades are dished for clay and are often a little wider. Overlapping titles are separated in drainage spade vs trenching shovel.
Blade, lift and treads
There is no single correct width. Maker figures we used run from about 105 mm on that Masseys Newcastle to about 180 mm on a Richard Carter 16 inch all-steel Newcastle, which also quotes 100 mm of lift and 2.8 kg. Faithfull’s contractors’ draining blade, the size on the FAIASDMYD in this set, is 380 mm long by 90–150 mm across. A Wonkee Donkee guide to cable-laying shovels in general puts the cutting edge at about 115 mm and the blade height at about 280 mm. Do not paste 115 mm onto the Bulldog 5CLAM. Its listing does not state a width.
Lift is the raised shoulder that holds spoil for a moment. Richard Carter’s 100 mm and Masseys’ 55 mm are two different Newcastles, so some lift is the buying point, not one millimetre target. Foot treads matter when you stamp a narrow blade into clay, because there is little shoulder for your boot. Roughneck advertises treads. One Bulldog review says there is no return flange, because that user throws the blade rather than standing on it. If you only stamp, buy the tread.
Shaft, weight and a forged head
About 700 mm is a common trade shaft. A longer shaft lets you cut without standing in the hole. In this set the Spear & Jackson 2154HK has a 711 mm metal shaft and the Faithfull FAIASDMYD a 0.7 m tubular shaft. Roughneck’s title length is 1,070 mm in fibreglass and Neilsen’s is 1,080 mm. Draper’s ash shaft is 980 mm with a T-handle. The JCB dimension line is 149 cm overall, on a 3.1 kg grafting-named tool. The KMF is a short D-grip, about 81 cm and 1.2 kg.
Listed weights run from that 1.2 kg to 3.1 kg. Weight helps the first stab in hard ground and tires a smaller user. A forged head and socket is the contractors’ quality claim. BS 3388:2004 covers forks, shovels and spades. Exceeds BS 3388 on a maker PDF is that maker’s claim, not a test we repeated. A fibreglass shaft can be lighter. It is not an insulated tool. HSE says use insulated tools when hand digging near electric cables. None of these eight listings is sold as insulated.
How to read a listing
Read the pattern name, then the conflicts, then the review count. The KMF bullets say a stainless shaft and blade while the material-type line says alloy steel, and the listing shows 5.0 from two reviews. That is not the same evidence as 4.7 from 2,403 reviews on the Spear & Jackson 2154HK. The Neilsen material-type line says carbon steel and fibreglass, and a separate blade-material line says fibreglass. Treat that as a conflict, not as a fibreglass blade. A Roughneck product-type line calls the handle short while the title says 1,070 mm. Use the title figure.
Entry prices in this captured set sit at about £11 to £16: Bulldog 5CLAM £11.54, KMF £12.99, Neilsen CT1150 £14.99, Spear & Jackson £16.20. Mid shelf prices are about £21 to £30: Roughneck £21.54, Faithfull £26.56, Draper £29.96. The JCB is £44.99 with 17 reviews. A two-review listing can be a light short shovel. It is not a contractors’ drainer with a known blade size. Check welds before the first stamp. Prying a blade as a crowbar is not ordinary digging. One Faithfull review found sharp welding wire left on a weld.
Common questions
What is the difference between a drainage spade and a normal spade?
A drainage spade has a long narrow blade for a deep slot, so you move less spoil than with a border or digging spade. A normal digging spade is wider and better for beds and for shifting soil. Spear & Jackson’s guide treats the draining pattern as its own tool, separate from a square-mouth shovel. If the hole only needs to be a little wider than a pipe, the narrow blade is the one that matches.
How wide should the blade be?
There is no single UK width. Faithfull states 90–150 mm across a 380 mm draining blade. One Newcastle sold by Masseys is about 105 mm across, and a Richard Carter Newcastle is about 180 mm. A general cable-laying description is about 115 mm at the edge, and that figure is not printed on every cable-layer listing. Choose the width that matches the pipe plus a little room.
Do I need foot treads?
You need them if you stamp the blade into clay, because a narrow head has little room for a boot. Roughneck states treads for that reason. Some cable layers are used with a throwing action, and one Bulldog user says a return flange is absent. If your method is to stand on the blade, buy the tread. A tread will not save a thin blade that you lever like a bar.
Is a fibreglass shaft better than steel?
Fibreglass in this set is the longer, lighter option: Roughneck at 1.98 kg and Neilsen at 1.5 kg, against steel drainers around 2.7 kg. One Neilsen review still doubts the shaft when lifting clay. Steel is what the forged tubular drainers use. Neither material on these listings is an insulated shaft for work beside a live cable.
What does a forged head change?
A forged head and socket is the claim that the blade and the joint were formed as solid steel rather than a thin pressing. Faithfull states a forged carbon manganese head on the FAIASDMYD, and Bulldog states a solid-forged head on the 5CLAM. The claim has to be on the listing you buy. A forged blade can still bend if you lever it.
Is a £12 listing with two reviews the same as a contractors’ drainer?
No. The KMF at £12.99 has two reviews, a short D-grip and a stainless-versus-alloy conflict. A contractors’ drainer in this set states a forged head, a shaft around 0.7 m or a known blade size, and hundreds or thousands of reviews. Price can sit in the same band. The evidence does not.
