When polishing a blade and transitioning from coarse to fine grits, do you wet the sandpaper or use it dry? Thank you in advance.
1500 is going to leave a satin finish, so plan your strokes so they all line up and move from edge to edge in the same direction. Do not start or finish a stroke in the middle if you are finishing the job with 1500. It can be a really cool effect.
In other word start at the tang, then move to and off the tip, then repeat starting at the tang again. This way all your scratches line up to a very nice effect.
If you are going to compound for a mirror finish then this is not nearly as important.
