I have been using the paper wheels for a couple of years. I have been pleased with the results. The drawer with the stones, systems, etc. does not get opened.
So, this morning I decided to free hand sharpen kitchen knives. Worked on 6 knives for about a half hour. They were (or so I though) OK. But, I was not quite satisfied. I decided to continue with the stones. Then I suddenly realized that I would rather not spend additional time with the stones - I just do not have the patience anymore. Being retired, I have more important things to do - rest, walk, read, shoot, etc.
I got the paper wheel set up out, and within 10 minutes had the kitchen knives and two others hair poping sharp.
Thus, a general realization, "paper sharpening wheels - when your time is important to you."
I really respect those that like the challange of sharpening by other methods, and who can shave hairs, etc. I think that sharpening is a great hobby for those that find satisfaction from it.
Then I came to my second realization of the morning - my knives are much sharper since I switched to the paper wheels. I really think I never had the desire, time, or skills, to get my knives so sharp by hand. I use my knives a lot, and I like them usable sharp, which I can exceed quickly using the paper wheels.
My kudo's to Richard. His time and effort in this thread are suburb.
