Professional secateurs: a complete guide to choosing and maintaining yours

Good secateurs are the tool that makes the difference between enjoying pruning and ending up with a sore hand, a strained wrist and crushed stems. They're also the tool you'll use most in the garden, far more than any machine: for shaping shrubs, cutting back perennials, harvesting flowers for the vase, pruning roses and fruit trees, cleaning up dead wood and pinching out shoots. You don't need to spend €90, but you do need to understand what you're paying for, choose the right size for your hand and know how to maintain them, because well-cared-for mid-range secateurs last decades and cut better than an expensive pair left neglected.

In this guide you'll see the real difference between bypass and anvil and when to use each; how to choose the size and why it matters so much; the options for left-handers and small hands; the types of steel and the parts that really change the result; the ergonomics and cutting technique so you don't injure yourself; which secateurs to use for pruning each type of plant; maintenance in five steps; the signs that yours need attention; what to do for thicker branches; and a final recommendation for your garden. At the end, twelve frequently asked questions.

Bypass or anvil: the key decision

Bypass secateurs (double blade, scissor-type)

Two blades that cross like normal scissors: one sharp blade that cuts and a thicker counter-blade that holds the stem while the first passes. They make a clean, precise cut without crushing the tissue, which lets the plant heal quickly and doesn't leave a doorway for fungi. It's what you need for living wood: roses, ornamental shrubs, fruit trees, perennials, vine, thin bamboo canes. If you're only going to buy one pair of secateurs in your life, make it a medium-sized bypass.

Anvil secateurs (one blade falling onto a flat base)

A single sharp blade that falls onto a platform — the "anvil" — of hard plastic or soft metal. It cuts with less hand effort because it acts as a wedge, but it crushes the stem against the anvil at the last moment. It only makes sense for dry, dead wood, where the crushing doesn't matter because the tissue is no longer alive. On a green stem, it crushes the plant's conducting vessels, leaves an open wound that oozes and heals badly, and favours the entry of diseases.

Ratchet anvil secateurs

A variant of the anvil one that cuts in several progressive "bites", each without letting go. It multiplies the force and works very well for people with little hand strength or with arthritis, and for thick dead branches. It still crushes, so don't use it on living wood.

If in doubt, buy bypass. The anvil one is a secondary tool for cleaning up dead branches and dead wood, not the garden's main secateur. Many gardeners have both: the bypass for all the pruning work and the anvil for the winter clean-up.

Size matters (a lot)

Professional secateurs are made in several numbered sizes. One that's too big forces the wrist and tires you out in long pruning sessions; one that's too small forces you to make twice as many cuts and can't reach medium branches, so you end up forcing it.

Try holding the secateurs closed: you should be able to open and close your hand fully and reach the closing latch with your thumb without stretching. If the opening arc forces you to open your hand to the maximum (fingers fully straight), it's too big for you.

Closing and opening adjustment

Look for the one-hand closing: a latch or button you operate with your thumb without letting go of the tool or using the other hand. And an opening adjustment in 2-3 positions, to adapt the secateurs to the thickness of what you're pruning (less opening for fine, fast work, more for thick branches) and to the size of your hand.

For left-handers

There are specific left-handed secateurs with the blade and the latch on the opposite side. Right-handed secateurs used with the left hand force you to squeeze in the direction that separates the blades instead of bringing them together: it cuts worse, leaves tabs of bark uncut, tires you more and knocks the secateurs out of adjustment over time. If you're left-handed, it's worth looking for the right model, even if the choice is more limited.

Types of steel and parts that really change the result

Ergonomics and technique: pruning without injuring yourself

• Cut with your wrist straight, not bent. Turn your shoulder and elbow to orient the secateurs, not your wrist.
• Place the branch at the base of the secateurs, near the axle, not at the tip: there the leverage is maximum and the effort minimum.
• The sharp blade towards the part of the plant that stays; the counter-blade towards the piece being cut off. That way the cut is clean on the plant.
• Cut at an angle, about 5 mm above an outward-facing bud, so the water runs off and the new branch grows outwards.
• If the branch doesn't give way at the first try, don't force it or lever sideways (it bends the blade): take it out and use loppers or a saw.
• Alternate hands in very long sessions, or take breaks: secateur fatigue builds up in the forearm and elbow (epicondylitis, "tennis elbow").

Which secateurs to use for pruning each plant

Maintenance in 5 steps: 5 minutes that give years

1. Clean after each use. Remove sap and soil with a rag. For the sticky resin of conifers and fruit trees, a little alcohol, mild solvent or even oil dissolves the crust. Dried sap built up on the axle is what makes secateurs "go stiff".
2. Oil the axle and the blade with a few drops of light oil (3-in-1, sewing machine oil, camellia oil) every week of use. Open and close the secateurs several times to spread it.
3. Sharpen only the outer bevel of the blade. With a fine diamond stone or a medium-grit sharpening file, give 10-15 gentle strokes following the factory angle (about 20-25°), always in the same direction (from the inside towards the edge). Never touch the flat inner face of the blade or the counter-blade: if you round that face, the secateurs stop cutting cleanly forever.
4. Adjust the central nut until the blades close with no sideways play (they shouldn't "wobble" to the side) but without rubbing hard. Well adjusted, the open secateurs close on their own by their weight when you tilt them slowly.
5. Disinfect with 70° alcohol when going from a diseased plant to a healthy one, especially with roses and fruit trees with symptoms of fungi or fireblight. A soaked rag or a few seconds' immersion is enough.

Store the secateurs closed and with the lock on, hung from a hook or in their holster, never loose in a drawer knocking against other tools. Once a year, take them apart completely (remove the central nut), clean all the parts, check the state of the spring, oil and reassemble.

Signs that your secateurs need attention

• The cut leaves a tab of bark uncut: blunt blade, or the central nut is loose and the blades separate when you squeeze.
• The branch "escapes" towards the tip instead of being cut near the axle: lack of adjustment or lack of sharpening.
• It's hard to close the secateurs: dirty or dry axle (clean and oil it), or a tired spring.
• The blades open on their own or don't return to the open position: spring to be changed.
• Rust on the blade: remove it with fine steel wool and oil before it reaches the edge; then always store dry and oiled.
• Noticeable sideways play: tighten the central nut; if the play persists, there's wear in the axle or bushing and it's time to replace those parts or the secateurs.

For thicker branches

One-hand secateurs cut comfortably up to 20-25 mm depending on the model and your strength. Above that:

• Loppers (two-handed pruners): long handles that give leverage; they cut branches of 25-45 mm. With a telescopic handle you reach high branches without a ladder. There are also ratchet ones for up to 50 mm with little effort.
• Folding pruning saw: for branches of 40-100 mm; it makes a clean cut (use the three-step cut technique so you don't strip the bark), it's light, cheap and fits in a pocket.
• Pruning chainsaw: above that. See the guide to electric chainsaws.

Forcing one-hand secateurs on a branch that's too thick knocks the axle out of adjustment, nicks the blade, bends the blade and can injure your wrist. Always use the tool of the right size.

And battery secateurs?

There are electric secateurs that cut branches up to 30-40 mm just by pressing a trigger, effortlessly. For a private individual they're an expensive luxury (€250-600) that only pays off if you have lots of fruit trees, a vineyard, a lot of hedge area or a strength or arthritis problem in the hand. For ornamental garden pruning, good manual bypass secateurs are enough, they don't run out of battery, there's nothing that can break and they force you to look at each cut, which is also good for the plant.

Final recommendation for your garden

• Occasional use (pots, a couple of shrubs): mid-range bypass from a known brand, size M, €20-30.
• Garden with a rose bed, shrubs and the odd fruit tree: professional bypass with a replaceable blade and spares available (spring, counter-blade), €50-70. It's the one that gets passed down.
• Complement for everyone: cheap anvil secateurs for dead wood, a folding pruning saw and loppers for anything over 25 mm.
• Fruit trees or vineyard in quantity, or hand problems: consider battery secateurs, or at least bypass with a rotating handle and a smooth mechanism.
• Small hands: size S and check the opening arc before buying.

Frequently asked questions

How often do you need to sharpen secateurs?

With home use, 2-3 times a season. If you prune lots of roses or fruit trees, every 3-4 weeks in high season. The sign is that the cut stops being clean and starts leaving tabs or tearing the bark.

Can I sharpen the secateurs with a normal file?

Better a diamond stone or a fine diamond file. A coarse hardware-store file leaves the edge with microscopic teeth that tear the stem instead of cutting it. Always follow the original bevel angle and sharpen only on the outer face.

What maximum diameter do one-hand secateurs cut?

Between 15 and 25 mm depending on the model, the size and your strength. Above that, use loppers or a pruning saw: forcing the secateurs ruins them, and the wrist pays for it.

Are secateurs with a replaceable blade worth it?

Yes, if it's a pair you're going to use for years. When the edge can't take any more after many sharpenings, you change just the blade for a few euros instead of throwing away the whole tool. It also usually indicates that the manufacturer also offers spare springs and counter-blades.

How do I disinfect the secateurs between diseased plants?

Wipe the blades with a rag soaked in 70° alcohol, or immerse them for a few seconds. Always do it when going from a rose or fruit tree with symptoms to a healthy one; in a single pruning session you can spread fungi, viruses and bacteria all over the garden if you don't.

Why do my new secateurs no longer cut well after a few months?

The common causes: the central nut has loosened with use (tighten it), dried sap has built up on the axle and between the blades (take it apart, clean it and oil it), or you've cut wire, a stone or gritty soil and nicked the edge (sharpen it). It's rarely a manufacturing defect.

Store the secateurs open or closed?

Closed and with the lock on: it protects the edge, prevents accidents when rummaging in the drawer and keeps the spring at rest. You only leave them open to oil or sharpen them.

Are secateurs any use for cutting lawn edges or for large plants?

For lawn edges there are specific long-blade shears (or an edger). For occasionally cutting tall grass, hand shears. Using secateurs for that blunts them quickly because of the silica in the grass and the soil it carries.

Which is better, an aluminium or a steel handle?

For home use, forged aluminium: it's almost as strong as steel and considerably lighter, which is appreciated in long pruning sessions. Forged steel is reserved for very intensive or professional use.

Are secateurs with a rotating handle worth it?

They reduce blisters and palm fatigue in hours-long pruning, because the handle turns following the natural movement of the hand when closing. Many people love it and others find it odd. If you can, try it before buying.

Can I take secateurs on a plane or send them by post?

On a plane, only in checked luggage, never in the cabin. By post, no problem, protecting the edge with the holster or with cardboard.

How long do good secateurs last?

Professional secateurs with replaceable parts, well maintained, last a whole gardener's lifetime: you change the blade and spring every few years and the body lasts decades. They're one of the few garden tools that really do get passed down.
