My old man used to sharpen his blades but Ive found that you really need to give them an Axe cut or thick edge or they go blunt in record time.
The other issue I find is that they do get bent out of shape after a while which obviously effects their efficiency so like Joe I just buy a new set every 6 months or so AND a new bolt set too.
BRRRRRRRRRR Rattle rattle rattle PTUI! rrrrrrr cough cough cough................. Silence.......... Creak mutter mutter NOW where did that %#$*&^%$# blade go?
