Hello,
I have started to plane white oak and I have noticed black streaks on the wood. It looks like some metal contamination from my beloved no.5 hand plane. Also, the area behind the mouth continually turned black. I cleaned it with sandpaper but, it started turning black again. I have vacuumed the plane and also made sure that I do not cary leftover particles from the sharpening to the plane.
What might be the cause of this issue?
Thank you.
