I have the cheaper set that Highland Woodworking sells, the metric set. I really like them. They were very easy to get flattened on the back and sharpened. I have primarily used the 6mm and 10mm ones for mortise chopping and have had no issues. I run them over the strop 30 times when I’m done and have not yet had to resharpen them. I’ve used the 26mm one for some paring as well.
