How to use bonsai tools on the cut in front of you
Updated: 22 October 2026
The shoot you meant to tidy has thickened since last weekend, and the cutter is still in its sleeve. How to use bonsai tools means naming that job, then picking up the one tool that matches it. A thin shoot is scissors. A branch at the trunk is a concave cutter, and only if the jaws will close on the base. Wire comes off in short pieces. Roots wait for a spring repot. The sets are lined up in the [bonsai tools comparison](/hub/garden-tree-and-hedge-shears/bonsai-tools). Peter F. checked the listings.

Match one tool to one job
Spread the tools out and decide the cut before a jaw opens. Scissors take a thin shoot in one close, with the blades meeting before the handles reach a finger. A concave cutter takes a branch at the trunk: seat the base in the jaws and close, which is the Wazakura order, and that guide keeps wire out of those jaws. A knob cutter stays down until a stub is left. A wire cutter cuts wire.
A small jaw forced around wood it cannot span, or scissors on a spiral of wire, is the quick mistake. One UK listing, the YZNlife scissors, drew a review in which the blades would not cut and the handles overlapped onto a finger. Stop when that happens. If the pouch is still being chosen, use the bonsai tools buying guide.
Taking a branch off
Seat the base of the branch in the concave cutter, close once, and keep the branch still as the blades meet. If the jaw is too small for the whole base, stop, because bites around the sides tear bark and can bend the edge. RHS bonsai advice covers the repot and leaves the shape of a branch wound undescribed. Bonsaibotanist.org argues that a flush concave cut can enlarge the wound compared with leaving the branch collar, so leave the collar in place. The RHS steps do not call for wound paste.
A knob cutter comes only if a stub is still standing. It will not finish a branch the concave cutter could not close. Which jaw you pick up first is on the concave cutter versus knob cutter page.
Wire in short pieces, then the roots
Above 2 mm, the National Bonsai Society method is short sections, from the outside in, each piece freed where it lies. Pulled off in one turn, thick wire tracks into the bark. If a turn is already sunk, stop.
Take the wire off when it starts to bite. Bonsai Direct's rule of thumb is a check every couple of weeks: a few weeks for elm or ficus, and months for pine. The three VOUIU sets include a wire cutter. The Penitue set, the Wazakura set, and the mini kits do not. If the pouch has none, leave the wire in place.
Roots are a later session. In spring the RHS order is a small rake to loosen the compost, sharp scissors on roots you can see, then water and shade.
After the session, and when you stop
Wipe the sap off, dry the steel, then oil it, and case the blades. Oil on a wet blade holds moisture on the steel, so the cloth comes first. The case keeps the concave edge off the scissors in the pouch. A UK review that calls a mini kit suitable for children is not an age grade.
Stop if the trunk has split, if the wire is already under the bark, or if you are about to grind a jaw you do not understand. A bonsai club is the next step, and also when the cutter will not close.
Common questions
Which tool do I pick up for a thin shoot?
Scissors, while the shoot severs in one close and the blades meet before the handles reach your fingers. A shoot with a base at the trunk needs a concave cutter seated on that base. If the scissor blades will not meet, put them down. Crushing the growth because they were already open leaves a flat stub and a tired edge.
How do I take a branch off at the trunk?
Seat the base in the concave cutter and close once, holding the branch still. If the jaw cannot take the whole base, leave the branch. RHS advice covers the repot and does not describe this cut. Bonsaibotanist.org argues that a flush concave cut can enlarge the wound compared with leaving the branch collar, so leave the collar in place.
When do I use the knob cutter?
Use it after the branch is off, and only if a stub is still standing. It hollows that remnant. It will not close a cut the concave cutter has already failed, even when the jaws look alike. Until a stub is there, the knob cutter stays on the bench.
How do I get wire off without tearing the bark?
Cut wire above 2 mm into short sections and work from the outside in. That is the National Bonsai Society method. Check every couple of weeks in the growing season, a Bonsai Direct rule of thumb, and remove the wire when it bites. Elm or ficus may mark within a few weeks, and pine often after months. A buried turn is the moment to stop.
What is the RHS order for a repot?
Repot in spring. Loosen the compost with a small rake, cut visible roots with sharp scissors, water, and then shade the tree. The rake frees the compost before any scissor cut. A solid plate of root means the loosening step is unfinished. Shade the pot afterwards where it sits in full sun.
What if the cutter will not close on the branch?
Stop pushing. The branch may be thicker than the jaw, or the blades may be failing, and more force is how handles overlap a finger. A review of the YZNlife scissors described blades that would not cut and handles that met the hand. Grinding a new profile is its own stop. Case the tool and ask a club or a more experienced grower.
