Is there any formula to asses the life span of a blade?

Is there any way to price a second hand blade according to its date of purchase and brand?

Yes, spare ones last longer. The harder you hit the more they break. If your blade lasts longer than usual your distance is improving.;)

I'd only give a nomial value or a seocnd hand blade -- what you're really buying is the guard, socket and grip.
