Great topic Pottzy! I am a Diablo guy. I have 6 that I use for the Saw Stop. All different tooth count and sizes, from 6 1/2 to 12. I have diamond blades for the tile saw, and 4 1/2(?)for the small cordless Ryobi. I do not sharpen them any more....I throw them and get new. Sharpening around here, does not pay.
I have Bosch hollow ground blades for my hand jig saw and Lennox for my recip saw....except I do have some Dialbo recip blades for for tree limbs or destructing. It is super aggressive.
