If you mean this one
http://www.sears.com/shc/s/p_10153_12605_00994843000P?vName=Tools&sbf=Brand&sbv=Stanley then yeah, I have one in my truck toolbox. Picked it up at WallyWorld for about $15 last year.
The "interlock" ensures only one blade can be open at a time. The utility blade has a button for quick changes.
It's got a heavy-spined 420C blade. The liner lock and handle seem quite stout, though I haven't done any heavy twisting.
One-handed opening is not easy, though possible. You have to push the thumb stud in, hard, to unlock the blade so it will open.
Despite the rubber insert, I find it slippery when wet. Solved that with some coarse emery cloth (and further solved it, by accident, when I had urethane glue on my hands).
It's a big sucker, too. Not unobtrusive on the belt. The handle is quite large and roundish, so it's not quite as handy as other utility knives.
As a worksite knife, where it may be abused, lost, or stolen, it's a decent choice. I doubt I would buy another one though.
