Silky 27033 13" (330mm) Silky Zubat Arborist Handsaw is one of the most used handsaws by professional arborists worldwide - so Silky tweaked it into the Arborist version. The Zubat Arborist has the same design and aggressive curve as the Zubat Professional 330, but with extra large teeth that slice through wood faster and with less effort than ever before.
