Not alot to talk about here because we all have them and they have been around for many years. Here is my current collection of one hole punches. Some of these I just picked up. I do like the A&W carded one and it may be the oldest of the bunch. The older ones are made in the US and the newer ones overseas. The best ones have a catch plate under it to keep the paper holes for easy discard. The blue handled one on the right is the one I use the most. Add them all to your collection.
