Since 2003 D3, Protection has been a maker of hand made high quality leather goods including saps & blackjacks, and impact weapons. Ranging from keychain saps and coffin flat saps to aluminum batons. Every item is made by David Doerr, in western Canada. Using only the finest leather and hardware available. These leather pieces are made of excellent quality materials and craftsmanship."D3 Protections flat saps, Finger saps and blackjacks are all made of the highest quality American made leather tanned by Herman Oak and are built for many years of loyal service. Flat saps consist of a flat spring with a lead ingot cast to it, this is known as the "frame". The frame is then covered with multiple layers of thick leather and sewn through all the layers. D3 Protections blackjacks are all made around custom made frames cast by me. The frame is then wrapped with various types and thicknesses of leather." These are some fantastic paper weights!

The strap is a tapered 4 oz black leather lined with glazed pig skin and with the conventional rivets, Total weight of 12 oz for 3 layer sap. New from maker.
