Boundary Blade® is a patented 5 Level Fence Tester & Pocket Knife Agricultural Tool with global appeal.
It allows farmers to easily check electric fence current and "walk away with their mind at ease".
Conventional fence testers are bulky. Invariably, they are on the tractor, in the jeep or back at the workshop, never to hand. This innovative device has removed the awkward size & bulk of existing fence testers with no grounding cable required.
