No more struggling & hitting with heavy hammers.

The Jonko cone wedge has been designed specifically for use within a tree and to fell small to medium size trees with a slight back-lean. Following one year of field testing a variety of different profiles & thread designs we managed to come up with a versatile & highly functional product – you are sure to find a use for it in a broad range of applications.

Strong – made to handle an impact driver over and over again, its made of high grade steel for repeat use.

Easy to Use – the Jonko can be easily used with one hand with a ratchet/socket wrench or an impact driver [high torque].
