Quick answers
- What is the difference between bypass and anvil pruners?
- Bypass pruners and loppers have two blades that slide past each other like scissors, so they cut live green stems cleanly. Anvil types press one blade onto a flat surface and suit dead, dry wood but can crush living stems.
- What thickness can secateurs and loppers cut?
- Secateurs cut stems up to about 2 cm. Loppers handle about 4 to 5 cm, and anything thicker needs a pruning saw. Forcing a tool beyond its limit damages the blade and the plant.
- How often should I clean pruning tools?
- Wipe blades after each session, and disinfect them with rubbing alcohol or a diluted household disinfectant when you move between plants, and always after cutting out disease.
- When should I call a professional for tree work?
- Call a qualified arborist for any branch thicker than about 10 cm, anything near power lines or buildings, and any cutting you can only reach by climbing or using a ladder with a saw.
Key takeaways
- Bypass blades cut live stems cleanly, and anvil blades are best kept for dead wood
- Match the tool to the branch: secateurs to 2 cm, loppers to about 5 cm, saws beyond that
- Longer lopper handles of 50 to 80 cm give leverage but add weight
- Clean and disinfect blades between plants to stop disease spreading
- Leave high, large or power line branches to a qualified arborist

The best pruning tools and loppers are the ones that match the thickness of the branches you cut, so a clean, sharp bypass blade, the right handle length and a saw for bigger wood protect both you and your plants.
A blunt or wrongly chosen tool tears bark, leaves ragged wounds and lets disease in. This guide explains the main types of pruning tools, how to match each to a job, how to look after blades and when to stop and call a professional. It’s general information, and your local extension service, a qualified arborist or the Royal Horticultural Society (RHS) can add advice for your trees and area. Links on this site may earn a commission, and that never changes what we recommend.
It belongs to the Trees and Shrubs guides and works with How to Prune Trees Safely, Shrub Maintenance and Renewal Pruning and How to Plant a Tree Properly.
Tree work can cause serious injury. Wear gloves and eye protection, never cut above shoulder height with a saw, and keep well away from power lines. Leave large or high branches to a qualified arborist.
Best pruning tools and loppers at a glance
| Tool | Cuts up to | Best for |
|---|---|---|
| Bypass secateurs | About 2 cm | Roses, shrubs, perennials and live stems |
| Anvil secateurs | About 2 cm | Dead and dry wood |
| Bypass loppers | About 4 to 5 cm | Overgrown shrubs and fruit tree branches |
| Ratchet loppers | About 4 to 5 cm | Weaker hands and tough, dry wood |
| Pruning saw | 5 cm and thicker | Larger branches within reach |
| Pole pruner | About 3 to 5 cm, at height | Branches up to 3 m, without a ladder |
| Hedge shears | Soft growth up to 1 cm | Trimming hedges and topiary |
These are typical values. Always check the maker’s stated capacity, and use a saw as soon as a tool starts to struggle.
How to choose pruning tools and loppers
- Measure what you cut. Check the thickest stems on your plants, and choose secateurs, loppers or a saw to match.
- Choose bypass for living wood. Two sliding blades give a clean cut that heals quickly.
- Check the handle length. Lopper handles of 50 to 80 cm give leverage, and telescopic ones reach farther but weigh more.
- Test the grip. Close the tool a dozen times in the shop, and make sure it doesn’t pinch your hand or tire it quickly.
- Look for replaceable blades. A tool where the blade and spring can be replaced lasts many years.
- Add a saw. A curved or folding pruning saw with a sharp, hardened blade handles the cuts that loppers can’t.
How pruning tools and plants affect each other
Clean cuts help bark close over a wound quickly, whereas crushed or torn stems stay open and let canker and fungal spores enter. Roses, apple and pear respond best to sharp bypass blades just above a bud, and dead wood on lavender, buddleia or old shrubs can be removed with anvil cutters or a saw. Cutting out diseased wood on a tree and then moving to a healthy plant with the same blade can carry infection across, so disinfect between cuts.
Heavy loppers and long saws also put strain on your wrists, so choose lighter tools if you prune for hours. Winter pruning of apple and pear removes crossing branches and lets light reach the centre, while summer pruning of plum and cherry avoids silver leaf and bacterial canker. Your extension service or the RHS lists the right timing for each tree.
A worked example: renewing an old shrub
Imagine an overgrown mock orange with stems up to 4 cm thick. Use bypass loppers with 70 cm handles to cut about one third of the oldest stems to 15 cm above the ground, one stem at a time. A folding saw handles the two stems that are 5 cm thick, and secateurs tidy the thin crossing growth. Disinfect the blades before you start and once more if you cut any dead or diseased wood. Repeat the process over 3 years, and the shrub renews without losing its shape. Check the cut stems for pale, healthy wood inside, because dark, dry wood means it is dead.
Caring for pruning tools and blades
- After each use: wipe off sap and soil, and dry the blades.
- Every month in the pruning season: sharpen with a diamond file, working along the bevel at about 20 degrees.
- Between plants: wipe blades with rubbing alcohol, and always after cutting diseased wood.
- Each winter: oil the pivot and spring, and store the tools dry.
- When parts wear: replace the blade or bolt before you replace the whole tool.
When to call a professional
Leave branches thicker than about 10 cm, any work near power lines or buildings, and any cutting from a ladder with a saw to a qualified arborist. A chainsaw on a tree is not a beginner’s job, and a fall from a ladder is the most common serious injury in home tree work. A professional carries insurance and knows the rules on protected trees, so check with your local authority before you cut a tree with a preservation order.
How pruning cuts affect plant health and growth
A sharp bypass blade makes a clean cut that bark closes over within a season, whereas a torn wound lets canker enter apple and pear. Pruning a rose just above an outward bud directs growth away from the centre and improves the airflow that reduces black spot, and cutting lavender after bloom prevents bare, woody stems. Mulch of 5 cm protects roots after heavy pruning, compost feeds new shoots, and water helps a renewed shrub recover in dry weeks.
Clean tools stop blight and canker spreading, and a pruning saw cuts through a 5 cm branch without tearing the bark. Summer pruning of plum and cherry avoids silver leaf, and winter pruning of apple lets light reach the centre and improves fruit. Birds nest in hedges from March to August, so check before you trim. Your extension service or the RHS lists the right month for each tree, and a vet can advise if a pet chews pruned yew or laurel, which are toxic.
Which pruning tool for which branch
| Branch or stem | Tool | Why it suits |
|---|---|---|
| Up to 1.5 cm across | Bypass secateurs | Cut cleanly without crushing the stem |
| 1.5 to 4 cm | Bypass loppers | Long handles give leverage for thick stems |
| 4 to 10 cm | Pruning saw | A curved blade cuts on the pull stroke and stays controlled |
| Dead or hard wood | Anvil loppers | The blade presses on a flat anvil, which suits dry wood only |
| Hedge tops and soft growth | Hedge shears | A 20 to 25 cm blade trims a flat top quickly |
Never use anvil loppers on live green stems, because the crushing action bruises the tissue and invites disease. Wear gloves and eye protection for any cut above shoulder height, and leave branches near power lines to a qualified arborist.
Keeping pruning tools sharp and clean
A sharp blade makes a clean cut that heals fast, whereas a dull blade tears bark and leaves a ragged wound where disease enters. Sharpen the bevel with a fine diamond file at the original angle, usually 20 to 30 degrees, and stroke away from the cutting edge. Wipe blades with methylated spirit or a household disinfectant between plants when you prune diseased wood, which stops fungal spores and bacteria spreading from one shrub to the next.
Oil the pivot and the spring every month in the pruning season, and tighten the pivot bolt until the blades close without wobble. Store tools dry, and replace worn blades rather than the whole tool when the model allows it. Good secateurs last 10 years or more with this care.

Common mistakes
- Using anvil blades on live stems. They crush tissue and slow healing.
- Forcing a tool past its limit. Switch to a saw before the blade bends or snaps.
- Skipping blade cleaning. Dirty blades spread disease between plants.
- Cutting too close or too far from a bud. Cut about 5 mm above it, sloping away.
- Working above shoulder height. It’s tiring and dangerous.

Frequently asked questions
Are ratchet loppers worth buying for weak hands?
Yes, they suit people with a weaker grip or sore wrists. A ratchet mechanism cuts thick stems in several small squeezes instead of one hard one. The trade-off is a slower cut and a little more weight, so check the maker's stated capacity and test the grip first.
Can I sharpen my own secateurs at home?
Yes, with a fine diamond file or sharpening stone. Work along the original bevel, usually 20 to 30 degrees, stroking away from the cutting edge. Wipe off the metal dust, oil the blade and pivot, and replace the blade if it is chipped or deeply nicked.
What size pruning saw do I need for garden trees?
A saw with a blade of about 15 to 25 cm suits most branches from 4 to 10 cm thick that you can reach from the ground. Curved blades cut on the pull stroke. The three-cut method in How to Prune Trees Safely stops bark tearing on heavy limbs.
Why do my loppers crush stems instead of cutting them?
Anvil loppers crush live stems, and blunt or loose bypass blades do the same. Use bypass blades on green wood, tighten the pivot bolt until the blades close without wobble, and sharpen the bevel. Cutting stems thicker than the stated capacity also bruises them.
What is the best way to disinfect pruning blades?
Wipe the blades with rubbing alcohol, methylated spirit or a diluted household disinfectant, following the product label. Do this between plants and after any diseased wood. Remove sap first, because dirt shields germs, then dry and oil the blades to stop rust.
Do I need a pole pruner for high branches?
A pole pruner helps with branches up to about 3 m without a ladder, but it is not essential. Wear a helmet and eye protection, stand clear of the drop zone, and never use one near power lines. Heavy or high branches are a job for a qualified arborist.
How tight should the pivot bolt on secateurs be?
Tight enough that the blades close without wobble or gap, but loose enough to open and shut freely. A loose bolt lets stems slip between the blades and tear. Check it each time you sharpen, and add a drop of oil to the pivot and spring.
Is it OK to use anvil loppers on dead branches?
Yes. The blade presses onto a flat anvil, which works well on dry, dead or hard wood. Keep anvil tools away from live green stems, because the crushing action bruises tissue and slows healing. Dead wood cuts most easily in dry weather.
How long do good secateurs last?
Quality secateurs often last 10 years or more with care. Wipe and dry them after each use, sharpen the blade, oil the pivot, and replace worn blades or springs instead of the whole tool. Models with replaceable parts usually last longest, so check what the maker supplies.
What should I wear when pruning with loppers and saws?
Wear sturdy gloves and eye protection every time, and a hard hat for any overhead work. Long sleeves help against thorns on shrubs such as berberis. Keep cuts below shoulder height, because tired arms and falling wood cause most injuries.
