I work alot with epoxy composites- which usually have to be extensively sanded before finishing. In an effort to cut down sanding, and the dust, I picked up a scraper and found that this did a great job.- till it got dull. Now I can’t seem to put a good hook on the edge.
I bought 3 German-made scrapers- and when they arrived I founf they had no edge- it was left to the individual craftsman (Hah!) to establish his own hook (I’m told). So whats the trick?
