Loose Wedge Mortise & Tenon Joint
A variation of the mortise & tenon joint which features a removable piece (the tusk).
This allows the joint to be disassembled by simply knocking the tusk back out. Great for furniture that needs to be taken apart again.
There are many possible variations to the shape of the tusk, often including a taper that will allow the joint to tighten as the tusk is hammered in.
