飛塚製鋏所 Tobisho SR-1 200mm Bonsai Pruning Shears — Hitachi YCS-3 Steel, Slim Acute Tip

Tobisho SR-1 200mm Bonsai pruning shears are professional-grade Japanese secateurs forged from Hitachi YCS-3 steel for precise, durable cuts on bonsai and garden trees.

The Tobisho SR-1 is the brand's signature, widely respected by professional gardeners and bonsai artists for its blade geometry, edge retention, and balanced feel. Built with YCS-3 Hitachi steel, these 200mm shears combine a slim profile and acute tip for accurate work around delicate branches and refined pruning tasks. The SR-1’s design focuses on clean cuts to help maintain branch health, while the overall build emphasizes long-term reliability and repeatable performance in studio or outdoor settings.

How do these shears perform on delicate bonsai branches?

The SR-1 is built for controlled, low-impact cutting suitable for fine bonsai work. Its narrow, sharp blades let you make precise snips close to the branch collar without crushing wood, so shaping and wiring tasks are simpler and neater.

• Thin blade profile for access to tight branch junctions
• Acute cutting edge to minimize fiber crushing
• 200mm length balances reach and maneuverability
• Tip geometry aids work near trunks and compact foliage

What materials and craftsmanship go into the SR-1?

The SR-1 uses YCS-3 carbon alloy made by Hitachi — a steel chosen for edge retention and toughness. Tobisho’s production focuses on precise blade shaping and consistent heat treatment so each pair delivers predictable cutting performance and the potential for resharpening.

• YCS-3 Hitachi steel for a durable, sharpenable edge
• Heat-treated blades for consistent hardness and toughness
• Hand-finished edge geometry for clean slicing action
• Solid construction aimed at repairability and longevity

How do these shears stand up to everyday garden use?

Designed as a standard model in Tobisho’s lineup, the SR-1 is meant for regular pruning tasks in both garden and bonsai contexts. Its robust steel build and straightforward mechanics handle frequent use while remaining serviceable with basic maintenance like cleaning, oiling, and sharpening.

• Suitable for routine pruning of small branches and shoots
• Easy to clean and maintain after outdoor use
• Replaceable or resharpenable edges extend usable life
• Balanced length for general garden versatility

What should I know about size, handling, and maintenance?

At 200mm overall length, the SR-1 strikes a balance between reach and fine control. The handle design and weight distribution support repeated cuts without excessive hand fatigue, and simple upkeep keeps performance consistent season after season.

• 200mm length for precision without sacrificing reach
• Ergonomic balance to reduce wrist strain during extended use
• Routine sharpening and light oiling recommended after cleaning
• Inspect pivot and screws periodically for tightness and smooth action

Who is this for: the Tobisho SR-1 200mm is aimed at serious hobbyists, bonsai practitioners, and professional gardeners who need a reliable, finely honed tool for shaping and routine pruning. If you value a narrow blade profile, strong Hitachi steel, and a tool built for repeatable precision, the SR-1 offers a proven Japanese-made option. It’s best for users prepared to perform basic maintenance to preserve the sharp edge and smooth operation over many seasons.
