It's awesome to meet someone in the field who has firsthand experience. Ya, there are always two sides. The micra scissors excel at cutting cat5 - in fact that's their primary purpose for me and are usually too dull for paper after a month or two. I'm on my third micra. I think I may have got my first right around the turn of the century... so I guess they last 5 years or so.
Interesting discussion.
Regarding sharpening the Micra scissors, I've found that a DMT "Credit Card" stone to be ideal for sharpening the Micra. The Credit Card stone is very thin, so you can place the angled cutting edge of the scissor blades on the stone nearly back to the pivot. Work the blade back and forth on the stone till you work up a burr. Then lay the flat side on the stone and polish off the burr.
I buy Micras in bulk from the auction sites and get them with the scissors in all sorts of sad states (repeening the pivot rivet fixes wobble) and haven't had a pair yet that I couldn't get sharp enough to push cut wrapping paper.
A small, long phillips would be a nice addition to the Micra and I'd be willing to trade out the tweezers for that.
