And now, a reality check ...
Cutting through small wires at work. Hmm, it can be done, best case scenario is telephone wire - soft copper - that needs trimming or such. Of course, the idea is to fold the wire over the blade, and saw through the insulation then the wire, often blade up, and when parted the blade jumps through about 4-10 inches where you restrain it.
I know you are probably not wanting to carry an extra tool, so I will forego suggesting wire cutters. Try an Vic Swiss Army knife (or others) that have the wire cutter notch on one blade, an electrician's knife, or a small pair of multipliers that can cut wire - they make some nice ones keychain size that give a lot of usefullness with little bulk. I have picked up a few Vic's over the years and sharpened out burnt notches in the main blade, they have been good knives after. So far the temper is ok there.
Asking a knife to do chores that are not in the design envelope isn't wrong, but there are better tools for each job, and you get it done with a higher probability of success. I used a 16oz ball peen just last night trying to loosen a stuck collet on a 4 1/2" angle grinder.
Yup. But what the heck, two pipe wrenches wouldn't loosen it, either. The new grinder is much better.
