Excellent Scraper-- I purchased this super hard scraper to fabricate a small length of curved back band on a curved window. Only 30'' was needed and wanted to avoid paying the small mill shop $150 to run a 10' piece--and waiting 10 days for delivery. Although that was a reasonable price. So I used an angle grinder and a bench grinder to cut out the back band profile on this cabinet scraper. Grinding a sharp knife edge and then burnishing that sharp edge over, as is the method in Japanese hand tool use, then drawing the scraper on the cypress blank. After about 200 pulls, the profile 'magically' appeared. Imperfections were sanded out with 80 grit. This scraper was made of rigid metal that held an edge. It can't be filed, so a bench grinder and a diamond blade on the angle grinder was needed. All was well.---Thanks WoodCraft !!
