The Slide Hammer Stake Hole Punch is a helpful tool when using silhouette decoys under adverse weather conditions. It is designed to produce a stake sized, six inch deep hole in extremely hard ground, frozen ground, or through ice. The hole punch is a self-contained unit that consists of a housing, internal hammer, and knife assembly. Simple in design and use, it’s operation is loosely based on the old fence post driver idea. The Slide Hammer is definitely another “weapon” in the arsenal of the waterfowler that wants to hunt under the harshest conditions when the birds love to fly.
