Lovely Old Hand Scraper

Locked away in a drawer, probably for decades.

I'd love to drum up some info about the hand scrapers I found in the shop this winter. There is a handful of them of various shapes and I'd love to learn how to use them correctly. Indeed I've had to use a scraper when there was no alternative for machining. Don't know if I'm really doing it right, though, but the scraper has gotten me out of a bind (no pun intended).

As I understand it, the above pictured scraper is a bearing scraper for use on curved surfaces.
