Koban — Edo-period gold
小判 — In Edo-period Japan, the koban was the gold coin of the realm: oval, hand-struck, and carried by samurai and merchants alike. At Knives & Stones, Koban are how we say thank you — every dollar you spend on knives, stones and tools earns gold you can spend on your next piece.
Koban from a purchase become available 30 days after your order (our returns window). You can see your available and pending Koban any time — the gold chip in the menu is yours.
Koban discounts apply to product prices only — shipping is always charged separately.
TiersThe Steel Ladder
Your tier follows the steel of your blade — named for the steels a Japanese smith reaches for as the work gets more serious. Tiers are based on your last 12 months of spending (excl. GST & shipping), so your status reflects the collector you are now. A large banked Koban balance also holds you one tier below its level — loyalty is never wasted.
| Tier | Qualify (12-month spend) | Benefits |
|---|---|---|
| Kigami紙 | Everyone | Earn 5 Koban per A$1, from your first order |
| Shirogami白紙 | A$1,000 | Free handle installation · 50% off handles · plus all Kigami benefits |
| Aogami青紙 | A$3,000 | Free handle or magnetic blade guard with every knife — and if your knife already ships with a saya or guard, +3,500 Koban instead · plus all Shirogami benefits |
| Tamahagane玉鋼 | A$5,000 | Early access to select makers (Mazaki, Tetsujin, Manaka, Takamura and more — one early-access knife per order per month) · free handle upgrades · plus all Aogami benefits |
Reach a tier and it’s yours for a full year from the day you earn it. To renew at your anniversary, spend at least 40% of the tier’s qualification during the year — otherwise you’ll step down one rung (your Koban stay untouched either way).
