Name that tool again??

Why would one use vice grips to squeeze a hose fitting? Aren't vice grips used to hold something or spin it once it grabs on? I would think to squeeze a fitting down tight, one would use something solid and longer with more leverage. I don't know, just thinking aloud again.

Years ago I used a cheap pair to weld up a quick and dirty crimper for stovepipe. And, you can buy them that way, as well

Too bad Vise Grip has become yet another sorry state of Chinezeoization
