I have used this on my saw blades and cutters for about five years now. Not only does it improve the cut, but prevents buildup of pitch and resin on the blade surface. I spray it on the blade surface before and sometimes during use. I don't bother to wipe off any excess, it doesn't affect the cut. This stuff is especially helpful on the small bandsaw blades (3/16), I use for cutting out bandsaw box's, I can definitly tell the difference in the tight radius cuts. I also use it extensively on my Freud thin kerf saw blades, it seems to help the blades run cooler and I get less "burning" in the hardwoods I typically use. This is a real good product and I would recommend it to everyone who values their expensive cutting edges.
