When I first saw this tool it seemed a little silly...do I really need a tool to set a brad?
But, honestly, after I tried it, it really is very helpful. I don't know how many times I've been poked under the fingernail trying to open a tiny brad, this tool does it for you. Is seems simple, and it is. It's made by We R Memory Keepers and sells for about $6.99, but I've seen it at most of the places that have coupons.
