How to Get a Mirror Polish?
Here's a question from a BLADE reader:
I've been having trouble getting a mirror finish on my blades, whether it be carbon or stainless. I can get them mostly polished, but it seems I always have sanding scratches after hand sanding that won't buff out. I change direction with each grit sanding to 2,000 grit,
and everything looks fine but when I finish buffing, the center always seems to be cloudy looking.

Try to buff a couple of times early in the sanding, this will make the scratches not removed by the previous grit easier to see. If your last grit was 400 at a diagonal you would not expect to see any scratches parallel with the blade. You can also mix up your angle so you can determine the grit of the scratches. If I am getting clouds I clean my wheel and apply fresh compound and finish the buff with a lighter touch.

I use 3 lights,so that I get a little light from different directions. It helps me see the scratches better. At first I will cover the blade with a black felt tip pen. Some times I do this twice,just to make sure that I got all the scratches at that grit. I use the felt tip on say 120 grt,then on 220 grt. It helps with the "big" scratches. I then go to the next grit say 320 & I sand in 2 different directions. Then I slowly move on to the next grits. Buffing will help as per PatrickKnives.I then do what David Pitt reccomends Buffing with white,K&G Green, then finish with noscratch pink.
