ParaHatchet™ PRO Features ParaHatchet™: This tough 4mm thick stainless steel hatchet easily chops firewood and limbs. The multi-size hex wrenches (3/8", 9/16", and 11/16") can be safely accessed with sheath in place. A quick-action rope cutter on the back adds extra functionality, and the black-oxide finish reduces rust and protects the blade.
