Einhell strimmer blade or line

Updated: October 2026

The knives lasted on the lawn and shattered on the patio, and the listing never said those were different jobs. An Einhell strimmer blade or line choice is the cutter, not the battery and not the star rating. This page sorts the ten amazon.co.uk listings in the [Einhell cordless grass trimmer comparison](/hub/lawn-and-garden-equipment/einhell-cordless-grass-trimmer) into plastic blades, nylon line, and the one box with both. Prices are from 19 October 2026. The Products Compared editorial team did not run the heads on a test strip. A purchase through our links can earn a commission at no extra cost to you.

Two cutters, and a third that is not in this set

A plastic blade is a small knife on a plate, usually sold with 20 spares, for a soft fringe the mower left. A nylon line is a spool that advances, for a wall, a flag or a path. A knife on paving blames the cutter for the wrong task. The third cutter is a metal blade. Which?'s public guide puts that plate on a brushcutter. Einhell's 1 July 2021 article says the same about a motor scythe: line near walls and stones, plastic blades for open grass, metal only on a scythe. The Agillo was removed for that reason. Brambles belong on the buying guide. Glasses on, guard on. The flower guard shields plants. It does not shield you.

When line is the better fit

Choose line when the head will run beside masonry, slabs, gravel or a kerb. The 18 V line bodies are the GE-CT 18/28 Li Solo at about £64.95 and the GE-CT 18/30 Li at about £64.98. Neither includes a battery. The 28 cm model is 4.5 from 1,904 reviews, with a 180 degree head and automatic thread tracking. The 30 cm model is 4.4 from 1,135 reviews, with a 90 degree head and a wheel kit. Three pence is not a quality gap. The 36 V GE-CT 36/30 Li E-Solo is a stated single 2 mm thread, 30 cm, about £94.95, and it needs two packs that are not in the box. How to clear a spool is on the how to use page.

When plastic blades are the better fit

Choose blades when the work is open grass and the head will stay off stone. The six listings are about £32.56, £39.95, £48.43, the about £51.54 2.0 Ah kit, the about £68.99 kit with amp-hours not printed, and the about £79.95 2.5 Ah kit. The price spread is battery and head angle, not a change of cutter. The lightest body, 1.2 kg at about £32.56, is a blade tool. The 2022 one-tester note found that kind of head fine on grass and snapped on concrete. The about £48.43 GE-CT and the about £79.95 kit state a turning head and still cut with knives. The about £39.95 solo carries the main table's top-pick badge and states no angle. Buy it for open grass.

The listing that includes both

The GE-CT 18/25-1 Li-Solo, article 3411256, states 20 plastic blades and one line spool, a 25 cm title width, a 180 degree head and a metal flower guard. It is about £59.99, with no battery, and it is 4.6 from 90 reviews. That is a thin base beside 13,827 reviews on the plain GE-CT 18 Li Solo. The weight cell says 3.11 kg, the same figure as the 36 V listing, and it may be wrong. Use it when you already own one 18 V pack and you have both edges. Fit one cutter at a time. Amazon prints 7,000 rpm. Do not replace that with another model's 8,500 or 9,000. If the garden is brambles, this spool is not a metal blade.

Common questions

Which listings are blades, which are line, and which are both?
Blades: about £32.56, £39.95, £48.43, £51.54, £68.99 and £79.95. Line: about £64.95 at 28 cm, £64.98 at 30 cm with wheels, and £94.95 for the 36 V 2 mm body. Both: the about £59.99 GE-CT, with 20 blades and one spool, and no battery. A kit price does not turn a knife into line. The main table's cutting-system column is this same split.
Will blades survive a patio edge?
Do not plan on it. Einhell says to be cautious with blades near hard surfaces, and a 2022 one-tester write-up saw them snap on concrete paths. Reviews here describe blades leaving the head on stone. Twenty spares mean knives get replaced in ordinary grass use. They are not a promise along a flagstone edge. Stop at the grass, or fit line.
Is line less likely to break on a wall?
In the sense Einhell means, yes: line is what they point at walls and stones, and a plastic knife is what shatters there. Line can still break, jam or throw grit. The 28 cm body states automatic tracking, the 30 cm body states automatic jogging, and 36 V reviews often need the head opened. Glasses and the cutting guard stay on. Thread is not a reason to skip protection.
Does the 25 cm model really include both?
Yes. The GE-CT 18/25-1 bullets say it works with the plastic blades and with the spool, and the included list names 20 blades and one spool. The title and the size cell both say 25 cm. The battery is not in the box. Ninety reviews, and a 3.11 kg cell that may belong to the 36 V listing, are why it stays a specialist solo rather than the automatic pick.
Is the 36 V tool a blade machine?
No. It is nylon line, a single 2 mm thread, 30 cm, with a split shaft. It needs two 18 V packs and includes neither. It is not described as brushless, and it is not the Agillo. A higher price does not turn a spool into knives or into a metal brushcutter blade. Open grass and one pack point back to a 24 cm blade body.
