well, like I said.. it's ash, so parts of it the grain does complete swirls.. so i can't always scrape with the grain.. and yes, it's scraping across that makes that happen.
Mostly I wanted to know if there was something stupid I was doing.. but since it sounds like is a common problem, i don't feel so bad
I have been burnishing them quite a bit.. making sure sharpness wasn't an issue. so far, so good. I think i'll just have to scrape as much as I can, sand the rest, and try to blend it as well as I can. The scrapers leave such a nice surface, i just hate to sand it..
Thanks for the replies folks.
