The Slide Hammer Stake Hole Punch is a helpful tool when using silhouette decoys under adverse weather conditions. It's designed to produce a stake sized, six-inch deep hole even 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 easy to use, it operates much like the old fence post drivers. This is another great weapon in the arsenal of the waterfowler who wants to hunt in the harshest of conditions.
