The SILKY ZÜBAT ARBORIST edition features the same awesome handle as the Silky ZÜBAT, but sports a 13-inch ZÜBAT blade with extra-large teeth, giving you the saw you need when you're battling bigger branches. In addition to the new blade, the ZÜBAT ARBORIST also has a new scabbard design that features a 3-roller system that helps guide the saw into the scabbard, preventing premature wear on the scabbard.
