Pruning & hand tools
Secateurs, loppers or pruning saw: which tool should you use?
Choose by branch size, wood condition, tool rating and access. This guide shows where each hand tool fits, how to avoid forcing a cut and when the job belongs with an arborist.

Quick decision: match the branch, not just the tool name
Use bypass secateurs for smaller live stems that sit fully inside the blades. Move to loppers when a reachable branch is too thick or tough for a clean one-handed cut but remains within the loppers’ stated capacity. Use a pruning saw when the branch is beyond the loppers’ comfortable, rated cut.
That is a decision sequence, not a set of universal diameters. Cutting capacities vary by model and wood. GARDENA, for example, publishes model-dependent limits and gives different ranges for its own secateurs and loppers. Read the rating on your actual tool and leave margin for hard, dry or awkward wood.
- Small, green and easy to reach: start with sharp bypass secateurs.
- Thicker but still controllable from the ground: use rated loppers.
- Too large for a clean lopper cut: change to a pruning saw.
- Overhead, hung up, split, heavy or near services: stop and use a qualified professional.
Check four things before choosing
Look at the whole job before putting a blade around the branch. A tool can be large enough for the wood yet wrong for the access, the cut position or the risk below it.
- 1
Branch thickness
Measure at the point you intend to cut, not at the thin tip. Compare that measurement with the manufacturer’s stated capacity for the exact tool.
- 2
Live or dry wood
Bypass blades suit fresh growth because the blades pass one another for a clean cut. Anvil tools concentrate force against a flat surface and are commonly intended for harder, dry wood.
- 3
Cut position
Make sure the blades or saw can reach the intended cut without scraping the trunk, crushing neighbouring stems or forcing your wrist into a poor angle.
- 4
What happens when it releases
Know where the branch and tool will move after the cut. If you cannot control the branch from a stable position on the ground, treat it as professional tree work.

When secateurs are the right choice
Secateurs are for precise, one-handed pruning of smaller stems within the tool’s capacity. They are useful for flowers, shoots, suckers and shrub growth where you can see the cut and support the stem without putting your free hand in the blade path.
For green growth, bypass secateurs are the usual starting point. Keep the branch deep in the jaws, close to the pivot, and make one controlled cut. If the handles will not close without repeated squeezing, twisting the branch or adding a second hand, stop. Forcing the tool can crush the stem, damage the blade or send your hands into nearby growth.
- Choose a handle size and spring action you can control comfortably.
- Keep fingers and the supporting hand out of the closing path.
- Use the rated cut, not the maximum gap between open handles.
- Move to loppers before the cut becomes a strength contest.

When loppers make more sense
Loppers extend reach and use two handles to apply more leverage. They suit thicker, reachable branches that fit completely into the cutting head and remain within the maker’s rating.
Position the branch near the pivot, set both feet securely and close the handles smoothly. Do not bounce on the handles, add a pipe for leverage or keep chewing around the branch. Those are signs that the wood, access or tool is wrong. A clean switch to a pruning saw is more controlled than a half-completed lopper cut.
Long handles are not permission to work blindly overhead. Agriculture Victoria’s pruning material notes that long-reach tools can reduce accuracy around the branch collar. If you cannot see the cut or maintain a stable stance, reconsider the job.
When to change to a pruning saw
A pruning saw is the next hand-tool option when a branch is too large or tough for rated loppers, provided the branch is reachable, the cut is visible and you can control what will fall. A pruning saw has teeth and geometry intended for branches; it is not simply a short carpenter’s saw.
Let the saw do the work with steady strokes. If the kerf closes and pinches the blade, the branch is moving under its own weight. Do not yank or twist the blade. Reassess the support and cutting sequence before continuing.
Technique
Make the cut without tearing bark
For a branch you can safely handle, identify the swollen branch collar where it joins the trunk or parent limb. Do not cut flush through that collar and do not leave a long stub. Agriculture Victoria’s demonstration keeps the collar intact so the tree can close over the wound.
A branch heavy enough to tear as it drops needs its weight removed before the final cut. The three-cut approach starts with a shallow underside cut away from the collar, then a top cut slightly further out to release the branch. The remaining stub is cut just outside the collar. The first two cuts are there to stop bark peeling down into the trunk.
If the branch is too heavy to control, is above people or property, has tension in it, or requires climbing or a ladder, do not treat the three-cut method as permission to proceed. Engage a qualified arborist.
- 1
Locate the collar
Find the swelling at the branch base and plan the final cut just outside it.
- 2
Undercut the branch
Away from the collar, make a shallow cut from below until the saw begins to bind.
- 3
Remove the weight
Cut from above slightly further out. The branch should release without stripping bark towards the trunk.
- 4
Finish outside the collar
Remove the short remaining stub without cutting into the collar or leaving a long peg.

Sharp, clean tools make the decision easier
Sap, grit, rust and a dull edge can make a suitable tool feel undersized. Clean off residue, keep the pivot working freely and sharpen or replace blades in line with the tool maker’s instructions. Check lopper bumpers, bolts and handles, and confirm a folding saw locks as its own instructions describe before each use.
Clean tools between plants when disease transfer is a concern. Use a cleaning or disinfecting method appropriate for the tool material and plant problem, then dry the tool before storage. Do not make up chemical mixtures or combine products.

Safety boundary
When to stop and call an arborist
This guide is for small, reachable pruning from stable ground. Tree work can involve falling branches, unstable wood, hidden tension and electrical hazards that are not solved by buying a longer tool.
Before pruning, look for overhead and service lines. Energy Safe Victoria says only authorised powerline-pruning contractors should prune trees touching or close to powerlines. Contact the electricity distributor or local authority for advice rather than estimating a safe clearance yourself.
Also check local council rules before pruning a protected, significant or street tree. Permission requirements vary. Stop if the tree is storm-damaged, split, decayed, leaning unexpectedly, carrying a hung branch, or if the cut would be above a person, building, vehicle or fence.
- The work needs a ladder, climbing or an elevated platform.
- The branch could strike a powerline or service line.
- You cannot predict or control the branch’s fall.
- The tree is large, damaged, decayed or structurally uncertain.
- A council rule or tree protection control may apply.
