Today we tested Archer Australia Chainsaw Chain
Stihl MS460, 20" Tsumura Bar, Archer Full Chisel Chain, cutting windblown apple gum
After a tank of fuel, the chain held it's edge well and was still cutting like new.
Minimal chain stretch for a tank of fuel. We normally retension new chains after 5 mins of cutting. We did not retension this chain so we could assess the initial stretch.
