Bypass pruning shear Ø20 mm Hasami 8236-F01

This bypass pruning shear cuts branches up to Ø20 mm diameter. High-frequency tempered carbon steel blades feature electrochemical anodized coating for wear resistance. The stainless steel spring prevents rust and maintains elasticity over time. Rubber-coated handles include textured grips to increase friction and provide secure hold during extended use.

Manufactured in Japan, the tool weighs 250 g and measures 200 mm overall length. The slide-lock mechanism, molded in green plastic, engages with a simple thumb motion. U-shaped stamped steel handles distribute force evenly. Chrome-nickel plating on the anvil blade reduces friction during cutting.

Bypass Pruning Shear 20 mm Construction and Materials

Blade and Cutting Mechanism

The bypass cutting action uses two blades that pass each other like scissors. High-frequency tempering hardens the carbon steel to maintain edge sharpness. Electrochemical anodizing creates a protective surface layer that resists corrosion and abrasion. The anvil blade receives chrome-nickel plating to reduce friction and prevent sap buildup.

• Cutting capacity: Ø20 mm maximum branch diameter
• Blade material: high-frequency tempered carbon steel
• Surface treatment: electrochemical anodized coating
• Anvil plating: chrome-nickel finish
• Cutting type: bypass (scissor action)

A proprietary bolt fastens the two halves together. This design prevents loosening during repeated cutting cycles. The pivot point maintains alignment without requiring periodic adjustment.

Spring and Lock System

The stainless steel spring opens the blades automatically after each cut. Corrosion resistance eliminates the need for lubrication or replacement. The spring detaches for cleaning or maintenance. A green plastic slide lock secures the blades in closed position during storage or transport.

• Spring material: stainless steel
• Spring design: removable for maintenance
• Lock type: slide mechanism
• Lock operation: thumb-actuated

The lock engages with a single motion. Embossed markings on the green plastic indicate lock status. This system prevents accidental opening in tool bags or pockets.

Handle Design and Ergonomics

U-shaped stamped steel handles provide structural strength while minimizing weight. Soft rubber coating covers the grip area. Textured surfaces increase friction between hand and tool. The design suits right-handed users with medium hand size.

• Handle material: stamped steel, U-profile
• Coating: soft rubber with textured grip
• Hand orientation: right-handed
• Hand size: medium
• Overall length: 200 mm
• Weight: 250 g

The rubber absorbs vibration and reduces pressure points during repetitive cutting. Textured patterns prevent slippage in wet or gloved hands. The 200 mm length balances reach and control for typical pruning tasks.

Common Applications

This shear handles routine garden maintenance and light pruning work. Cut dead wood, shape ornamental shrubs, and harvest flowers or vegetables. The Ø20 mm capacity suits small to medium branches on fruit trees, roses, and woody perennials. Use for thinning crowded growth or removing water sprouts. The bypass action produces clean cuts that heal quickly, reducing disease entry points.
