Not relaxing to me, like the YouTube videos. It is difficult and frustrating. It is very easy to wreck things like brass threads. Often lots of things are seized up on anything more than a few years old. Fun all the same.
I do, I have a fine whetstone. I agree, properly sharp/shaped screwdrivers make a huge difference. I think I need a better roller sharpening guide, and lots more stuff. :)
