The new Rapid Duro 3 carbide-tipped saw chain
Stays sharp for at least four times as long
Resistance is futile: the new .325" Rapid Duro 3 carbide-tipped saw chain stays sharp for at least four times as long as conventional saw chains, even in extreme conditions. The extra hard cutters won't go blunt even if they come into contact with the ground and they're specially designed to handle wood contaminated with cement residues. So you can cut yourself some slack when it comes to sharpening your chain.
