Very basic tool question: what's the ideal tool to use to crimp a disconnected hose so that fluid doesn't flow out and so that both my hands can be kept free? I see a set of crimping pliers at Harbor Freight, but somehow that doesn't seem ideal. Seems like there must be something consisting of two parallel flat surfaces that can be tightened on the hose.

What do I need to get?

Thanks.
