Not intending hijack this thread but on the subject of blades, a lot has been said about brand and type of blades. My question is, how do you really know when a blade is worn out and needs to be replaced. I have cut entire projects with the same blade and it was still doing ok but I"m sure I should have changed it for a new one. I watch for any burning but as for speed of cutting, I haven't actually seen that time when I should have changed the blade. I will say though that I have noticed a huge difference between the reverse tooth blades opposed to the none reverse ones. The wood doesn't have that "jumpy" feeling.
