Pruners (also called secateurs) and loppers are cutting tools designed for pruning branches, cutting stems, and general garden maintenance. They use scissor-like or anvil-style cutting action to make clean cuts through plant material.
Hand pruners are one-handed cutting tools with blades typically 5–8 cm long. Cutting capacity is approximately 1.5–2.5 cm (0.6–1 in) diameter.
Bypass pruners have two curved blades that slide past each other like scissors. The cutting blade is sharpened on one side; the opposing hook blade is unsharpened and provides counter-pressure. Bypass pruners produce the cleanest cut and are preferred for live plant material because they do not crush the stem.
Anvil pruners have a single sharpened blade that cuts against a flat, soft-metal anvil. They are more effective on dead wood, where the crushing action of the anvil is acceptable. Anvil pruners generally require less precision but produce a less clean cut. They are best suited for dry, dead stems and branches.
High-quality pruner blades are made of high-carbon steel (such as SK-5 or 1080), often with a non-stick coating (PTFE/Teflon) to prevent sap adhesion. Some blades are hardened and tempered for edge retention.
Loppers are two-handed cutting tools with long handles (45–90 cm or 18–36 in) for increased leverage and reach. Cutting capacity ranges from 3 to 5 cm (1.2–2 in) diameter. Loppers use the same bypass or anvil cutting mechanisms as hand pruners.
Compound-leverage loppers use a linkage mechanism that multiplies the force applied by the user. This design increases cutting capacity but adds complexity and weight. They are particularly useful for cutting thicker branches with less hand strength.
Ratchet loppers use a stepwise cutting action, allowing the user to cut through thick branches in several increments. The ratchet mechanism holds progress between squeezes, reducing the peak force required.
Pole pruners consist of a cutting head mounted on an extendable pole (2–6 m), operated by a rope or lever from the ground. They are used for pruning overhead branches without climbing a ladder. The cutting mechanism is typically a hooked bypass blade operated by a pull rope.
Pruner and lopper blades should be cleaned with a solvent after use to remove sap and plant residue. Blades are sharpened with a fine diamond file or sharpening stone, following the original bevel angle. The pivot bolt should be lubricated with light oil. Anvil blades may require periodic replacement of the soft-metal anvil surface. Non-stick coatings should not be scraped or abraded.
