3D Nail with Anchor (Removable)

Professionals handling reclaimed wood are aware of the risks associated with saw blades hitting nails. My prior 3D Nail with Anchor idea remains effective for concrete, where materials are ground up for recycling. However, for wooden applications, I modified the spike to a hinged tab (red) featuring self-tapping threads that only cut when removal is necessary. To use it, insert like a nail, deploy the anchor using a small nail, and then recycle by unscrewing the entire assembly, including screw and bolt options.
