Since 2003 D3, Protection has been a maker of hand made high quality leather goods including saps & blackjacks, and impact weapons. Ranging from key chain 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 casted 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 casted by me. The frame is then wrapped with various types and thicknesses of leather." These are some fantastic paper weights! It is an old time book weight that holds books open, used in the not so distant past. David was contacted by woman who wanted a bunch of the old style book weights made and after a conversation, David agreed. He found that the book weights would make an ideal covert sap. David doesn't make them regularly, as they do take time to make due to the boning required to make them look nice. Fantastic paperweight. Hand stitched and constructed. New from maker.
