Yep, I've used these a long time back when I was a microbiologist, for categorising bacteria. Using two rods meant you could do an AND search in one operation.

Yep, I've used these a long time back when I was a microbiologist, for categorising bacteria. Using two rods meant you could do an AND search in one operation. Also, if you clipped the wrong hole, you could fix it with Sellotape. I can't remember what they were called though.
Fun to be reminded of them!
