Learn how to choose bypass secateurs that fit your hands and cutting jobs. This buying guide covers blade size, bypass vs anvil, ergonomics, and care.
Quick answer
Choose bypass secateurs for clean, healthy cuts on living stems up to about 23mm thick. Match the tool to your hand size and the stems you actually prune, and pick a model with replaceable parts so it lasts. For most Australian gardeners, a well-fitting bypass pair plus a rain gauge to track watering needs covers everyday pruning and garden monitoring.
Bypass vs anvil: which cutting action suits your garden
Bypass secateurs work like scissors: a sharp blade slices past a hook, so the cut is clean and the stem stays healthy. Anvil secateurs crush the stem against a flat block instead, which is fine for dead wood but damages living tissue. If you prune roses, fruit trees, or shrubs, bypass is the safer default. Reserve anvil pruners for dry, woody stems you plan to remove anyway.
- Bypass: clean cuts on green stems, better for plant health.
- Anvil: crushes stems, suited to dead wood only.
- For mixed gardens, start with bypass and add anvil later if needed.
Blade size and cutting capacity: match the tool to the stem
A secateur’s blade length and opening determine the maximum stem diameter it can cut cleanly. The Bypass Secateurs in our catalog handle anything too thick for scissors or shears but less than 23mm. That covers most shrub and rose stems. If you regularly cut thicker branches, you need loppers rather than secateurs. Never force a cut beyond the tool’s capacity; it strains your hand and damages the blade.
Ergonomics and hand fit: why small to medium hands matter
Secateurs are not one-size-fits-all. Handles that are too long force your hand into an awkward grip, causing fatigue and reducing control. The Bypass Secateurs are designed for small to medium hands, with a shape that is good to handle. If your hands are larger, look for models with longer handles or adjustable grips. Always test the opening action and handle spread before committing to long pruning sessions.
Replaceable parts and long-term value
Sharp, well-maintained blades cut cleaner and require less effort. Models with replaceable working parts let you refresh the blade, spring, or lock instead of buying a whole new tool. The Bypass Secateurs have every working part replaceable, which extends their useful life and keeps waste out of landfill. Check that spare parts are available for any pruner you consider, and learn to sharpen and oil the blade regularly.
Tracking rainfall to time your pruning and watering
Pruning and watering decisions go hand in hand. A rain gauge helps you know how much rain your garden received, so you can adjust irrigation and avoid overwatering after pruning. The Rain Gauge holds up to 12cm or 5 inches of rainfall and shows both inches and centimetres. Its rustic metal rod and sturdy glass vial make it a practical addition to any garden bed.
Decision rules for buying bypass secateurs
- Cut living stems up to 23mm: Choose bypass secateurs if your main pruning is on green, living stems within this range. For thicker branches, step up to loppers. Check the maximum cut diameter before you buy.
- Match handle size to your hands: If you have small to medium hands, look for secateurs designed for that fit, like the Bypass Secateurs. Larger hands may need longer handles. A comfortable grip reduces fatigue and improves cut quality.
- Prioritise replaceable parts: Models with replaceable blades and springs last longer and save money. Confirm spare parts are available before purchasing. A repairable tool is a better long-term investment.
- Skip anvil unless you only cut dead wood: Anvil secateurs crush stems and are not ideal for living plants. Use bypass for healthy growth and reserve anvil for dry, woody material. Bypass is the safer default for most gardeners.
- Add a rain gauge for smarter watering: After pruning, plants may need less water. A rain gauge helps you measure rainfall and adjust irrigation accurately. Pair your secateurs with a rain gauge for a complete pruning kit.
