I used this hand punch for 5/8" ribbon. I was surprised when I received the punch because the description says it punches a 5/8" ribbon hole, but this can only be achieved with multiple punched side by side. This is very easy to accomplish and this tool made short work of 100+ holes. My only drawback was the reach. It only went to about 1/2" in.
I like that the slot punch is light weight and easy to handle. I have small hands.
It does take a few practice punch to line up the next one but the "window" underneath helps. I wish they came in larger sizes.
