Chikamasa Pruning Scissors & Harvest Tools
Chikamasa is a Japanese manufacturer producing precision pruning scissors and harvest tools used by professional horticulture operations worldwide. Their scissor line spans straight-blade, curved-blade, spring-loaded, and Teflon-coated models in a range of blade sizes -- each designed for specific cutting tasks from fine canopy work to full-harvest trimming. Chikamasa tools are made from high-carbon stainless steel and are designed for repetitive use without fatigue.
Straight vs. Curved Blade Models
Chikamasa B-500 series straight scissors are the standard model for general pruning, training, and light harvest cutting. The curved B-500SF and B-500SRF models allow blade access at an angle without rotating the wrist -- reducing repetitive strain during long trim sessions and improving control around dense canopy structure. Both blade types are available in standard and Fluorine (Teflon-coated) versions. The Fluorine coating reduces resin adhesion significantly, keeping blades cleaner between wipes and extending the effective cutting time before cleaning is required.
Maintenance and Longevity
Chikamasa scissors are designed for disassembly and resharpening. The pivot screw can be adjusted to compensate for wear, and replacement springs are available for spring-loaded models. Clean blades regularly with isopropyl alcohol to remove plant resin, and oil the pivot point periodically to maintain smooth action. With proper maintenance, a quality pair of Chikamasa scissors lasts multiple harvest seasons in professional use.

Chikamasa FAQ
What is the difference between Chikamasa B-500S and B-500SF?
The B-500S is the standard straight-blade model with a high-carbon stainless steel blade. The B-500SF adds a Fluorine (Teflon) coating to the same blade -- the coating significantly reduces resin and sap adhesion, meaning the blade stays cleaner during extended cutting sessions. For harvest work where blades are cutting resin-heavy material repeatedly, the Fluorine-coated models maintain their cutting performance longer between cleaning cycles. The SF is generally preferred for production trimming; the standard S works well for training, clipping, and low-resin cutting tasks.
Are Chikamasa scissors spring-loaded?
Some models are. Chikamasa offers both standard (manual return) and spring-loaded versions. Spring-loaded models auto-open after each cut, reducing hand fatigue significantly during long trim sessions. The spring mechanism is replaceable if it weakens over time. For professional trimmers doing extended sessions, spring-loaded models are preferred for ergonomic reasons. For growers doing light pruning and training work where the extra spring mechanism is not needed, standard models are lighter and simpler to maintain.
How do I clean and maintain Chikamasa scissors?
Wipe blades with isopropyl alcohol (90%+) to dissolve resin buildup during use. For deep cleaning, disassemble at the pivot screw and clean each blade face individually. After cleaning, apply a small amount of lightweight oil to the pivot point and work the scissors open and closed to distribute. If the pivot screw has loosened causing blade slop, tighten a quarter turn at a time until the blades cut cleanly without binding. Replace the spring if it no longer provides full blade return. Chikamasa scissors are designed for disassembly and can be resharpened with a fine whetstone or sent to a professional sharpening service.
