Kencove's Staple Starter-Driver is very simple to use and has no moving parts to damage. Just insert the staple into the slot and hammer on the pin (instead of your finger!)
Prevents staples from mushrooming when driving into hardwoods. Simply insert the staple into the slot and hammer. A few additional strokes may be required to set staple to proper depth. Remember do not staple wire tight on line posts. Use a this driver with standard fence staples up to 8 gauge and the wide staple driver (TDSDW) when using 2" wide staples (HB2W).
