Description

Belgian Blue Whetstones (BBW) are used for finish sharpening on Hapstone or Edge Pro knife sharpeners. BBW stones are available in 6mm thickness, and are mounted on high quality aluminum blanks.

Belgian Blue Whetstone is mined in the Ardennes mountains in Belgium. BBW is natural slate with a high garnet content.

BBW stones are universal, and can be used to sharpen knives of any steel.

How to use

Belgian Blue Whetstones should be used with water. All that is required is to wet the BBW surface. There is no need to immerse the stone. During the sharpening, slurry with garnets are released from the BBW surface. The more garnets are released, the more abrasive the grinding compound becomes. Try to keep slurry on stone surface.

BBW stones do not have any minor defects. BBW stones always have a color pattern; this is not a defect.

BBW stone does not require any preparations. It is naturally lapped to extra-fine grit.

Q & A

What grit do these natural stones have?

Grit terminology is not applicable to natural sharpening stones, including slates. The behavior of a natural stone depends on its density and how good it was lapped. However, experts estimate BBW as 3000 - #4000.

Very nice performance. Advertised grit is as expected or better.

Belgian and Chinese Compared If you have read any of my reviews or comments here, you would know that I hand sharpen using Grit-O-Matic Stones. They are the perfect size (for me) on any blade. I sharpen everything from old Slip Joints, Modern EDC to Chef Knives with them. Those looking at Blue Stone may be wondering what is the difference and how do I know which one to choose. That is what this review is about; comparing the Belgian (4K Grit) and the Chinese (6k Grit) Blue Stones. Let’s get started. Appearance: Belgian – Top view – Is molted with blues, whites and purples that give is a 3-D look. Side view is more dense. Chinese – Top View – Bluish Gray and somewhat flat. Side view - Less dense than the Belgian. Water stands equally on both stone but dries a little fast on the Chinese. Feel when Sharpening: Here is where it get interesting. The feel of the blade while going back and forth would tell you that the Grit levels indicated are reversed. I used water to whet the stones. The Chinese you can feel the coarseness of the blade and there is no doubt on where the blade is in relation to the edge. It gives very good feedback. I would say this is the 4K Stone. The Belgian on the other hand, sucks the blade to the surface and keeps it there for the entire process. The best way to describe this is a bowling ball sticking to the lane surface. With this feel, you never know by feedback on where the edge of the blade truly is moving. The strokes are smooth. More like a 6k Stone. Both did a great job with the blade and if you are going to use them on your preferred sharpening system, either one would be a good addition for that mid-grade finish. If you want to feel the feedback and sharpen by hand, choose the Chinese. If you want a beautiful stone for your collection and you are only going to use it in your system, go for the Belgian. It is a looker! I would by it just to have it for jewelry for my collection. There is always nothing wrong with getting both and see if your test come out the same as mine.
