By "frequent" I mean every few days, or maybe 1-2 times a week, just enough to keep the shaft smooth to the touch. I'll give the shaft a light rub down with #0000 steel wool followed by 2000 grit sandpaper. I apply the same technique to the butt end (which I believe has an oil finish) when necessary, but much less frequently. I really like the result I get from this, but I don't know anything about wood and I don't want to do anything that might be harmful. Also, should I burnish with leather after the 2000 grit, or is just finishing with the sandpaper ok? Thanks for any info and replies.
