Shapton Glass Stone, 220 Grit, #50101.
210mm x 70mm, 5mm thick (total thickness is 10mm: 5mm of abrasive bonded to 5mm glass plate).
Don't be afraid of coarse stones! They are super useful and easy to use! Just watch your technique and vary your pressure and you can easily control the cutting, so you can get a fresh and precise edge quickly, ready for finishing on finer stones in no time.
Shapton GlassStones are very fast cutting and long-lasting. The ceramic abrasive is permanently bonded to a glass plate so the whole unit is very flat and very strong. The abrasive is extremely consistent and dense so you have a great feel and can produce very precise and clean edges, plus these have the convenience of splash-and-go sharpening (do not soak these stones).
The Shapton stone holder (sold separately) is designed to fit these stones perfectly and is quite heavy and tall, providing a great workstation. The more affordable Naniwa universal/adjustable stone holder also works fine for these stones.
This is the HR version version of this stone.
Made in Japan.
