Support BladeForums! Paid memberships don't see ads! I have a few big blades (convexed SP53, Junglas, condor bushcraft parang) that I like to do a lot of chopping on very hard dead wood. I tend to collect material from the wood itself directly on the side of the blade steel, especially on convexed edges. It doesn't entirely come off with water or even a little vodka. I put some wd40 on the blades after wiping them, but that wood fiber/resin or whatever it is is still showing. Will this lead to rust or damage to the steel? Is there a good way to remove it or scrape it off? Should I not worry too much about it? Thanks, any advice is appreciated.
