Shapton Glass Stone, 1000 Grit, #50202.
210mm x 70mm, 5mm thick (total thickness is 10mm: 5mm of abrasive bonded to 5mm glass plate).
This is a superb stone, an absolute must-have! Cuts fast, is very hard and long-lasting and leaves a superb edge, ready for easy and quick refinement with a finer stone. The Glass Stones are a real pleasure to use, and extremely consistent. Everyone loves this stone!
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.
Made in Japan.
