Shapton GlassStone 4000 Grit

For many sharpening progressions the 4k stone has a pivotal role. The 4k is often the first “fine” or “finishing” stone used. Following something in the 1k range, the 4k can produce a toothy but refined edge for a wide range of cutlery applications, or it can continue polishing an edge before stepping to an ultra-refined 8k or even 10k finish. The Shapton Glass 4k makes an excellent option in this grit range with the Shapton Glass line’s characteristic hardness helping produce precise edges, its fast cutting and slow dishing, and its splash and go convenience. These stones are bonded to tempered glass and measure 210mm × 70mm × 11mm (8 1/4" × 2 3/4" × 7/16") with 5mm of usable abrasive thickness. Each stone weighs about 14 oz (400g).
