Shapton RockStar Series

Shapton's 2024 whetstone launch - the RockStar.

Made of the same high-grade ceramic cutting medium in the popular Shapton GlassStone, the RockStar series comes with double the abrasives and loses the glass backing. If you already love the Glass stones, you will love these too.

These RockStar sharpening stones are great for sharpening abrasion-resistant, high-hardness powder-metallurgy steels. The abrasives within the stone are uniform and homogenous which allows for a fast-cutting, hard and durable whetstone. 

One thing to note as a point of comparison to the GlassStone series, the RockStars are formed under less pressure. So the RockStar may end up being marginally softer compared to the GlassStone. However, this might just be a nitpick at the finer details as both the RockStar and GlassStone are still extremely hard, typical of any Shapton Stones.

On the back of the package, Shapton recommends a short soak in water before use. In practice, we find the stone to be a true splash and go, however soaking the stone for a while does seem to improve sharpening feedback.

This Whetstone is:

• Splash and Go - No soaking required.
• Fast Cutting - Great for hard, high alloy steels.
• Hard Wearing - This stone dishes very slowly
• Strong Tactile Feedback
• Reasonably Priced
• Wide Range of Grit Ratings

Troubleshooting:

If your edge is sharp in some areas but not in others, check that you have deburred consistently throughout the edge. Also, make sure you have a consistent sharpening angle throughout the length of the blade.

You may have microchips on the edge if your edge cannot achieve sharpness at specific points on the edge. You may use a 400 grit stone or lower to remove these microchips.
