One-hand pruning shear FELCO 4 for large hands, 25 mm cut

This one-hand pruning shear for large hands cuts fresh wood up to 25 mm in diameter. Forged aluminium handles reduce fatigue during long work sessions. The upper handle curves to fit the palm. The lower handle features a tail hook to prevent slipping. A sliding latch locks the blade when not in use.

High-speed steel (HSS) delivers a sharp, durable cutting edge. The riveted anvil blade ensures clean cuts on green branches. A nickel-plated coil spring opens the shear smoothly after each cut. Each part carries a stamped code for straightforward identification and replacement.

Design for One-Hand Pruning Shear Large Hands

The handles are cast from high-strength aluminium alloy in two distinct geometries. The lower arm includes a curved tail stop. The upper arm bends to cradle the hand. Plastic grips on both arms reduce slippage. A through-bolt and anti-rotation nut secure the pivot. Total length is 210 mm; weight is 220 g.

• Handle material: forged aluminium alloy
• Blade material: high-speed steel (HSS)
• Maximum cutting diameter: 25 mm
• Overall length: 210 mm
• Weight: 220 g
• Spring type: nickel-plated coil
• Lock mechanism: sliding latch
• Hand orientation: right-handed

Each component is numbered and available as a spare part. The blade, anvil, spring, latch, bushings, and fasteners can be replaced individually. This modular construction extends service life and reduces downtime. The model code is embossed on the handle for quick reference.

Blade and Anvil Construction

The cutting blade is made from high-speed steel and riveted to the upper handle. The anvil blade is riveted to the lower handle. Both blades are secured with replaceable rivets. The pivot bushing allows smooth rotation under load. The through-bolt is tightened with an anti-rotation nut to maintain alignment.

• Cutting blade: HSS, riveted mount
• Anvil blade: hardened steel, riveted mount
• Pivot bushing: replaceable
• Through-bolt diameter: matched to handle bore

The blade geometry produces a bypass cut. The sharp edge slides past the anvil to shear green wood cleanly. This design minimizes crushing and promotes faster healing of pruned stems. Regular sharpening maintains cutting performance.

Handle Ergonomics and Grip

The upper handle curves inward to fit the palm and fingers.

The lower handle extends straight with a tail hook at the end. Plastic grips cover both arms to reduce hand fatigue. The grip on the lower handle is longer to accommodate large hands. The grip on the upper handle is contoured for thumb placement.

• Upper handle: curved profile, contoured grip
• Lower handle: straight profile with tail hook, extended grip
• Grip material: molded plastic
• Hand size: large (L)

The tail hook prevents the tool from slipping out of the hand during overhead cuts. The curved upper handle increases contact area and distributes pressure evenly. This geometry reduces strain on the wrist and forearm during repetitive cutting.

Spring and Locking Mechanism

A nickel-plated coil spring returns the handles to the open position after each cut. The spring is captured between the two handles and does not require tools for replacement. A sliding latch on the lower handle engages a notch on the upper handle to lock the blade closed. The latch is operated with the thumb.

• Spring type: coil, nickel-plated
• Spring mounting: captured between handles
• Lock type: sliding latch
• Lock operation: thumb-actuated

The nickel plating resists rust and maintains spring tension over time. The latch provides secure storage and safe transport. The spring can be removed without disassembling the pivot for cleaning or replacement.

Common Applications

This shear is suited to pruning ornamental trees, bonsai, fruit trees, and perennial shrubs.

It cuts fresh green wood, young branches, and soft stems up to 25 mm diameter. Gardeners, landscapers, and arborists use it for shaping, thinning, and maintenance cuts. The lightweight aluminium construction reduces fatigue during extended sessions. The replaceable blade extends tool life in professional and home garden settings.

Replacement Parts and Service

Every component is assigned a part number and available individually. The blade, anvil, spring, latch, bushings, bolts, and grips can be ordered separately. This modular design allows users to repair rather than replace the entire tool. The manufacturer provides exploded diagrams and part lists for easy identification. Common wear items include the blade, anvil, and spring. Fasteners and bushings are also stocked as consumables.
