Robert Sorby Hardwood Scraper

[pennardesign]

Hi

This is my very first post! I must say I found the post on sharpening a skew chisel very good - I have been pulling my hair out as I thought I'd never get it re-ground - Thanks

Now I have a Robert Sorby hardwood scraper, this has a slight radius and two different angles. My question is how the hell do I sharpen this scraper? HAs anyone else done this, any help would be greatly received.

Thanks

Brian
