During the Flory sanding sticks demo video, Mr. Flory used a strangely shaped scraping tool that none of us had seen before. Dan Attilio happened across it by accident, and it turns out that there are several tools in the series. The one that Flory used is the Alec Lagia Precision Chamfering Tool with a variety of cutting shapes.
Then there is the Alec R-Boko Tool with a variety of curved recesses.
And the Alec R-V6 for scraping inside concave surfaces (including ejector pin scars)
These look very useful, but at $28-30 apiece?
