i have a husky 51 w/ an 18" bar and have always used the oem chains. the oem chain has a square shoulder which leads to a point. i think it is chisel? i have been told that a chain with a rounded shoulder will not loose its edge as quick. can anyone point me in the right direction.
thanks in advance
