I'm building a board game that connects pieces together, like a puzzle, but they can be flipped over, so I have found a picture of what I think would be a good connector piece, but I'm not sure what it would be called.


A piece like this would help me connect my double sided pieces together in any configuration. What is this connector piece called?

  • If one side was attached, it would be a sliding dovetail joint.

This question would probably receive a better answer on Woodworking SE.

According to Wikipedia, as well as Canadian Woodworking, this is called a Dovetail key, Dutchman joint, or Butterfly joint. Another common name for it is a Bowtie joint/key. Below is the picture shown on Wikipedia:

Dovetail keys are used to hold together two boards or one board that has begun to split (to prevent further splitting). In this Youtube video, a woodworker further elaborates on its uses and also demonstrates how to make one.

  • Good find! The one caveat is that the woodworking context if I understand right this is a technique meant more for a snug, permanent join, and it implies this specific shape, as opposed to a more generic shape. So since the OP is making a board game with temporary connections and would likely be okay with some variety of shapes, this might not be a perfect analog. Still definitely useful for searching around, though.

  • @Jeformi is right, but these has been the most clear in helping me find something to make these with chipboard.

  • For future people, 1stopsquare.com/punches/customlist.html, punch 730 makes this shape, but is small
