Crust, I think you're getting upset for nothing. My tools have stops, but the stop isn't really functional. That is, when they're closed, there's a gap between the stop and the opposite handle.
I think the stop comes into play like this: you know how when you're cutting something rather large (perhaps too large for the tool - we've all done it! Lol) and the tool kinda stops cutting, so you squeeze harder and harder? Then suddenly SNAP! It cuts through quickly? The stop is there to keep the two cutting edges from passing by so far they get misshaped. They are supposed to bypass a little. Just not a lot.
