@!*% thatRich, he got me going on micro slides as well. As Snyder sez, for finishing only. The edges chip with too much pressure, then your scraped surface has ridges.
I use steel scrapers for a lot of work, even for final shaping. A good scraper will remove rasp marks in no time. I made mini scrapers to work in between carving etc. Wide, narrow, curved edges, straight edges, a nice variety makes the work hum along.
