Most pros wait until a shear bites before they act. By then the edge has already rolled and you are paying for corrective work. Pillar two exists so you stay ahead of that curve—routine care, scheduled sharpening, and documentation that protects every warranty. Follow this framework and even value-tier steel can run a decade longer than the catalogue promised.
Pro Tip: Bookmark the Maintenance & Authenticity hub alongside the Daily Care reference. We will pull from both throughout this guide.
This is the non-negotiable routine after every shift. Two to three minutes now prevents rust, tension drift, and warranty battles later.
I keep a backup cloth and oil bottle in my station drawer so this process never gets skipped when the last client runs late.
Weekly deep cleaning keeps grit out of the pivot and stops chemical residue from etching the blade. Monthly checks catch hardware fatigue before it wrecks tension systems.
At the end of each month, log the number of clients per shear and note any tension tweaks. Those notes tell you when an edge is approaching sharpening even if it still feels okay on the floor.
Sharpen before a shear hurts you. The intervals below assume you follow the daily ritual and rotate backups.
Tier / Steel | Typical interval | What to watch |
---|---|---|
Value 440C (Mina, Ichiro entry) | 4–6 months | Blunt cutting starts to push hair, tension drifts faster |
Value VG-10 (Ichiro K10) | 6–9 months | Slide work feels scratchy, extra thumb pressure appears |
Professional ATS-314 / Powder Metal (Yasaka, Joewell PM) | 6–9 months | Check for audible drag and plan staggered services |
Professional VG-10 (Juntetsu) | 7–10 months | Dry detail work loses glide, logs show more drop-test tweaks |
Premium Cobalt & Nano Powder (Mizutani, Hikari, Fuji MoreZ, Yamato, Kasho) | 9–12 months | Keep factory-authorised sharpeners on standby; document every visit |
If you travel, book sharpening two weeks earlier than usual. Road dust and humidity degrade edges faster than home salon work.
Convex edges demand specialists. Before you hand over a $2,000 shear, confirm the tech’s setup matches Japanese requirements.
Run through the Sharpening guide and the Sharpening technician checklist before every booking. If a tech won’t answer those questions, find another.
Australian humidity, beach sand, and interstate flights punish unprotected shears. Build these habits into your routine.
For full workflows, refer to the Travel maintenance guide.
When a shear misbehaves, follow the same diagnostic sequence every time. Clean the blades, re-run the drop test, and reference the Troubleshooting matrix before blaming the edge. Many “dull” shears simply have residue or tension drift.
Document every issue in your maintenance log: date, symptom, quick fix, technician contact, and outcome. Pair that sheet with the how to log shear maintenance guide. Accurate records prove due diligence to sharpeners, protect warranties, and show you when an edge is burning through service intervals faster than normal.
From Experience: If a shear fails the same way twice after sharpening—dragging during slide work or chewing at the pivot—retire it until a factory tech inspects it. Continuing to cut only compounds the damage.
