My preschool students need to build their thumb muscles to become strong writers; these hole punches do just that with an ease that hard hole punches don't. My kids love to punch away with these.
I've usually been happy with Staples products but this hole punch is cheap. It doesn't punch cleanly and it particularly won't punch several sheets of paper at the same time. A 'work horse' hole punch needs a comfort grip not anything this flimsy. Sorry Staples you blew it with this one.
Seems sharp enough and the hole size I needed. This is a replacement for the largest of 3 punches I use to put holes in mock-up panels of paper of thin plastic. I had to remove the "catcher". It prevented me from viewing the punched hole target and getting the precesion I require.
