Okatsune Whetstone

This stone was delivered within ~26 hours of making the order with free shipping. JTA gave excellent pre sale advice.

However, this stone warped significantly on first use on a pair of Felco secateurs that were quite blunt but still cut clean. It did improve the sharpness, but I couldn't get as far as I wanted due to the stone warping. It's quite crumbly and flattening it would leave only 2/3 rds left.

I'd got a diamond file instead which performs much better. The Okatsune performs nothing like Shapton Glass/Pro. You might get more millage as a hone than serious metal removal, but I'd get something else for that.

I emailed JTA with this pictures about these issues twice and didn't receive a follow up. Given the excellent pre sale service, I hope this is an anomaly.
