No more shattered wedges or hitting with heavy hammers! Designed for use aloft; the Shizll Jonko cone shape wedge is about the same weight as a conventional hi-lift aluminium wedge used for felling small to medium size trees with a slight back lean. The Shizll team spent a year field testing different prototypes and thread patterns before producing the most efficient cone wedge (high lift) on the market. The Shizll Jonko comes complete with Shizll RopeSlider, and spiral 'Ratchet' tether connection. The Shizll Jonko is ideal for tree work and a broad range of other applications such as emergency services, demolition, DIY, wood splitting, and much more. 1/2 inch ratchet not included.
