What are the Sakagen S218 Japanese Bonsai Shears (210mm) used for?
The Sakagen S218 bonsai shears are designed for precise trimming of fine branches, shoots, and leaves. They’re ideal for maintenance pruning, defoliation, moss trimming, and detailed shaping work where control matters. While built for bonsai, they’re also great for indoor plants, herbs, orchids, and other fine garden pruning tasks.
What does “210mm” mean and how do they feel in hand?
210mm refers to the overall length (about 21cm). This longer profile gives you extra reach and leverage without feeling bulky. At roughly 125g, they’re lightweight and comfortable for extended pruning sessions, provided you’re using them on the right material.
What are Sakagen S218 shears made from, and will they rust?
They’re made from high carbon steel, not stainless steel. Carbon steel holds a very sharp edge and delivers crisp cuts, but it can rust if left wet or dirty. A quick wipe, thorough drying, and a light coat of oil after use keeps them in excellent condition.
Can Sakagen S218 bonsai shears cut thick branches?
No. These are precision shears for fine branches and soft-to-medium growth. If you have to squeeze hard, twist, or force the cut, the branch is too thick. For heavier wood or trunk work, switch to concave cutters, loppers, or a pruning saw.
Can I cut roots, wire, or plant ties with these shears?
They can tidy small feeder roots during repotting, but thicker roots require a dedicated root cutter. Never cut wire, nails, or hard metal ties—this will chip or dull the edge quickly. Occasional soft plant ties are possible, but keeping them for plant material only will extend edge life.
Do these shears leave a concave cut like concave cutters?
No. Sakagen S218 shears make a clean scissor-style cut. For recessed, concave wounds close to the trunk, you’ll need a proper concave cutter. These shears are best for refinement and maintenance pruning rather than structural branch removal.
Are Sakagen S218 bonsai shears good for beginners?
Yes. They’re often considered a perfect first “proper” bonsai tool because they handle most day-to-day trimming tasks. Professionals also rely on this style for refinement work. The key is using them within their comfort zone and not forcing thick material.
Do they make cleaner cuts than cheap garden snips?
Generally yes. The carbon steel and traditional bonsai blade geometry are designed for clean, controlled cuts that reduce crushing and tearing. Cleaner cuts tend to heal better and look neater, which is especially important in bonsai aesthetics.
How do I know when the shears need sharpening?
If stems start crushing, fibres snag, or you need noticeably more hand force, the blades are either dirty with sap or becoming dull. Clean them first; if performance doesn’t improve, it’s time for a careful sharpening.
Can I sharpen Sakagen S218 shears at home?
Yes, if you’re comfortable sharpening tools. Use a fine sharpening stone and follow the existing bevel angle. Avoid over-grinding or changing the angle, as this can affect how the blades meet and reduce cutting performance.
How should I clean and maintain these bonsai shears?
After use, wipe off sap and debris, dry thoroughly, and apply a light oil to the blades and pivot. Isopropyl alcohol works well for removing resin and disinfecting between plants. Regular light maintenance prevents rust and keeps the action smooth.
Why do my Sakagen S218 shears feel stiff?
Stiffness is usually caused by sap buildup, grit around the pivot, or lack of lubrication. Clean the pivot area carefully, dry the tool, and add a small drop of oil. Work the blades open and closed to restore smooth movement.
What’s the safest way to store or carry them?
Keep the blades closed and store them in a sheath, tool roll, or dry pouch. Avoid leaving them in damp sheds or loose in toolboxes where moisture and knocks can damage the edge. Light oiling before longer storage is a smart habit.
How do I make Sakagen S218 bonsai shears last for years?
Use them only for suitable plant material, avoid wire and thick wood, clean off sap promptly, dry them fully, oil lightly, and sharpen correctly when needed. With simple, consistent care, quality carbon steel shears can last for many years.
