Interesting. Also, tell us about the "other news" too.
Apart from the switch to torx screws, there seems to be little difference between the first and second generations. The handles are "cut" or scalloped, on early and late versions of the tool, but that doesn't help closing the tool or keeping it closed, the springs you clearly see accomplish that. There's no internal spring inside the scissor head, but you can see the operating springs, they're the ones attached up near/inside the gear mechanism.At least that are my observations based on my early cross-cut. My Cross-cuts have definite spring-assisted action, both opening and closing the tool, so I am not clear why your early tool seems to not do this.
Both my original Crosscut, and my 2.0 had the same style tweezers. While these seem like they'd be harder to access in theory, in practice, I never had a problem.There are detents in the scissor blades that catch against the handles which provide the force to keep the tool closed for the 2.0. Those blade detents are not there in my original. In both of mine, the spring action was the same, assisting to open the scissor blades when the tool was in open position.I don't know how old my original was (probably purchased around 1995 or so), but still had 'patent pending' stamped on it.My original also had the hex nut construction.
Which version of tweezers did yours have? I like the first gen but not the second gen, they don't work very well.
