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).

  Possibly Perfect
Posted By: Cory

Still learning, but 4000 seems to be a good finish for a knife that gets used.
Splash-and-go is a nice touch and really do appreciate the quality of these stones.

  Pleasure to use
Posted By: Quinn - verified customer

This 4k is an excellent finishing stone for all Western knives and a perfect transition from 1000 to a true finishing stone in the 8k+ range for Japanese knives. It cuts HRC 54-58 knives very quickly and provides a saemi-gloss finish that is beautiful. On harder knives I always use this after my 1000 Cerax and before going to my Glass 8k or 10k to finish. It polishes out the 1000 grit scratches nicely and preps the knife for the final touches.

  Love this stone
Posted By: kendall - verified customer

I bought this stone last year along with a couple other shapton stones. I love it. It puts a nice quick finish on my work knives and is also great to give life back to my knives after a heavy couple of prep days.

This a great stone for touching up knives that does not need much work. A great final stone for some knives. It gives great feedback and is now my favorite 4000 grit stone.

  Great stone
Posted By: nicholas schubert - verified customer

Just like all other Shapton glasstone, this stone cuts rapidly with very little wear of the stone. Great stone for the transition between the 1000x and the 8000x.

These are nice stones - relatively fast cutting, long-wearing, etc. I use a 1000-4000-8000 set up & am happy w it. One word of warning - the stones are more fragile then they look/feel! It is surprisingly easy to break one...

THis will keep a mirror edge on all of your tools once they've been sharpened properly.

Great transition between a 1000 and a 8000 grit stone. Produces a nice first polish. I really appreciate not having to soak the stone before using.

I don't think that most folks appreciate how great these glassstones are-the GS 4K is a perfect stone to follow your basic sharpening stones. The point I appreciate the most about the glassstones is how fast you can splash them(no soaking needed)-a big plus in a busy kitchen...
