Thread: Shapton 16K leaving stria on bevel

I typically use mine as a "barber stone", when a razor starts to feel off.

Thank you very much for your generous offer but I think after lapping my hone we are starting to see some potential. I'll just carry on with it. Yes, you would think at the price they want for those hones they'd be silky smooth and flatter than pee on a plate but they aren't in either respect.

I used either 1K or 1.5K wet/dry to lap mine super smooth. Never saw stria like you are describing. Never needed many laps following a thuringian or coticule to get incredibly sharp edges.

My 16K will also produce those coarser looking stria, especially noticeable after the mirror polish left by the 10K. I've only used the DGLP on it. Definitely removes metal quickly.

I just bought a 16k. Mine too is leaving deeper stria, especially noticeable on back of a chisel. In use for wood I notice just a slight less amount of sharp compared to the dmt 1micron diamond paste I normally use. For shaving the edge is not as comfortable as my naniwa 12k but could be due to my inexperience with the hone or the fact that I’ve only had a chance to do one blade on it. It definitely makes a straight sharp and the shave I got may not of been the most comfortable but it wasn’t unpleasant. Post shave my skin felt good, which is saying something as I have fairly sensitive skin. This hone will live in my woodworking kit but will definitely come inside for the occasional razor. It cuts fast in spite of its grit rating and the feed back for both ww tools and razors I find quite satisfying.

Shapton doesn't recommend using the glass 16k on razors or chisels. They recommend it for knives and scissors. The 16k has a less dense particle distribution than the 10k and therefore leaves a chippier edge than the 10k. Shapton recommends going from 10k to 30k for razors

Yes, and exactly why new users of the 16K Glass Shapton are surprised at the size stria it leaves and a slightly harsh shave that produces. It is really noticeable for me coming from a 12K Naniwa finisher. A toothy edge may be good on knives/scissors but not so much on razors/chisels.
