Nice video, explains use as well as sharpening. Was just using one last night to clean up the glue squeeze-out behind the face frame on the cabinet I just glued up - fortunately not too much because it's on the inside of the cabinet. I use mine mostly for cleaning up the joints on face frames, final trimming on edge banding and so forth, and find that it does a nicer job than sandpaper. Tough on the hands though - I have damage to the tendon in the thumb on my left hand (the orthopedist told me it was a condition known as "Gamekeeper's Thumb") which makes using the scraper on larger projects a problem. I just bought the Veritas Scraper Holder
Veritas® Scraper Holder - Lee Valley Tools hoping it will help, haven't had a chance to use it yet but planning to give it a try when I flip the cabinet over and work on the face frame. I've had their Jointer Edger as shown in the video for many years and it works just like shown. The Jointer Edger came with a little sheet with pretty comprehensive instructions that I use, but there are a couple of good tips in this video.
