I just bought and am using for the first time,this. It is actually meant for crafts, but I saw it for sale on an AB site, thought it was weird to see, and then realized the potential. I used it to puncture holes very quickly into a Baby diaper that I am using as a booster, that way it will spread fluids better to the next layer of diaper. I am testing it out now with 2 baby booster diapers, and a certainties diaper on the outside, I will update if it worked well. In the past i just used scissors if i wanted to double my diaper up and make it work better, but that always makes a mess with the stuff inside the diaper escaping. Soon, I will probably use the same method to double up 2 dry 24/7's to create the ultimate, dry 48/14!!! It will be the ultimate diaper!
