Like I said in the chat a few nights ago, I've used the anvil atlas, which is the same set of jaws but in a true rotary housing. Solidity (is that a word?) of construction and raw hook holding power are second to none. Like others have mentioned, the Anvil vises are little tanks. My biggest issue with it is the lack of polish/finish. It seemed very 'rough cut', mass produced, etc. If Renzetti is like a Beretta shotgun, and Regal is a dependable deer rifle, and dyna-king is an AR-15...well then Anvil is your AK-47. Nothing pretty, fancy, or even terribly well-finished, but it'll do the job and take a beating without much of any loss in performance.
