Shapton Rock Star 4kPosted By: Steve Hamley

I’ve been a Glass Stone HR and HC fan for years, the HR is the best option for cutting the modern wear-resistant knife steels. The HR are also the go to for hard straight razor steels because you can’t push very hard on a razor, so a fast HR is ideal for correcting razor geometry.
I bought the 4k Rock Star and it’s very similar to the 4k Glass Stone, but there are some differences.
- If they maintain the price point, these are an exceptional value
- There’s no glass backing, but we’ve been gluing synths to tiles and glass for years
- The 4k Rock star is rated at 3u, the 4k GS is rated at 3.68u
- It’s recommended on the Shapton site to soak the stone for 5-6 minutes before use to improve the feel. I’ve always left water on my glass stones for a few minutes before honing.
I’m looking forward to acquiring more of them.
