Hey, never had one of these before. Wow, is it handy! This is the Lee Valley Veritas cabinet scraper. It is sharpened differently than a chisel or plane blade, but it’s really easy. Plus it has two burrs, once you go thru one, you have another ready to go.
Here’s a few pics and it being used on zebrawood for a morning bar top. Gets rid of any tearout very nicely and leaves the surface ready for a card scraper or sandpaper. I like it much better for flat surfaces because the bottom registers flat, as opposed to a card scraper. I actually like it better than my smoother because it’s fast.
It’s important to follow the instructions carefully, as they get you off to a great start in understand the sharpening process. Here’s a link to a great video on Fine Woodworking by Phillip C. Lowe about the use of cabinet scrapers, scraper planes, and hand scrapers.
