These 16" saws feature the ARS Super Turbocut blades. The blades are Marquench hardened to hold their razor sharp edge an extra long time. The high carbon tool steel blade is hard chrome plated for superior rust and sap resistance. The bark cutter is detachable, and the included adapter snaps on the SC-EXP Extension Poles. Comes with sheath to protect the blade (and you!) when not in use.
