Hi klattman,
I'm familiar with the Crunch and have seen a few pictures of the Kershaw, although it might have been under a different name? But the other poster took a different approach, which is what caught my attention. I couldn't find the specs on the smallest vise-grips, but the shipping weight with all packaging is 4 oz. So presumably the tool itself is about 3 oz. At $11, this seems like a lightweight and inexpensive way to get the pliers and wirecutter function of a multitool. I've had large tools like this for years in my toolbox, but I just didn't know that anyone made them in these very small sizes.
Of course, the downside is that it adds yet another thing to be carried around. Back to cardimon's problem...
