Take it to the grinder (I use a 180 grit CBN wheel, but others use white wheels) and create a hollow around the edge.








And you are done ...

As apprentices we used these Thumb Scrapers a lot. Particularly good on teak or other silica infested timbers. The quickest and easiest scraper to get a working edge on. Can be shaped to suit mouldings. Chip limiters from spindle moulder cutters can double as a thumb scraper.
