Wooddamon, some of mine are from flea markets too. The last one I got from a flea market was covered in rust, I walked past it twice with little more than a glance, then when I found nothing else to buy, went back and looked closer. It was rusty but not pitted, handles were tight but grungy, but I saw great potential when i picked it up. Got it cheap. It cleaned up well. It's the top drawknife in the first picture. A 10" Pexto. Yeah, I have some drawknives that aren't 'quite' as sharp, but I always liked my ring chasers to be fairly sharp.
Dbeaver, no, the platen is flat. I wouldn't mind getting a radiused one though.
