didn't mean to sound argumentative, sorry. I was wondering whether certain blades could be sharpened or if most nowadays were throwaways.Did anyone possibly tell you that blades 'Steel or Tungsten tipped' can (and are'- by true tradesmen' -sharpened when they lose their edge ?.)yeah but you can't be guaranteed of sharp blades if you buy em 2nd hand.
A good tradesman can tell when their blades lose their edge- by the effort the machine needs to exert. Then- He-/she gets them sharpened.
The more teeth on the blade- the better the cut.
Steel tipped blades give the very best cut- but they lose their edge very quickly. Tungsten tips last longer- but the cut is not quite as good. Only a true tradesman would notice the difference though--honestly.
Only trying to be helpful bud.
How would a tradesman sharpen a blade? on a standard grinding wheel?
