I’m looking for a certain unusual tool, and not having much luck so far. I don’t even know what it’s called, so I haven’t been able to search for it online. My dad used to have one years ago. It has a row of metal pins that slide through a metal base. You can press the pins against a shape, and the pins slide to conform to the shape. You can then use this as a guide to cut material so that it fits this shape exactly.
Can anyone tell me what this thing is called, or better yet, where to get one?
