I am with you on this.
As an engineer I am often in a position to admire designs that maximize efficiencies in size, weight, power, and cost, that don't also sacrifice utility, easy of use, and elegance. And some of my favorite hand tool innovations are good exemplars. John Zilliox's Park Metal Ware Xcel Multi-Head Wrenches, linked
here, come to mind. His brilliant mechanical design, motivated by engineering principles and practicality, not market chicanery, created the ability to put fifteen (15) different detachable open end wrench heads, ranging from 3/8" to 1-7/16" on a single shank, reducing the amount of steel (and also space and weight in a carry box or hanging on a rack) heretofore needed to constitute that DOE wrench set by ~65%, without losing effectiveness.
But sometimes efficiencies can go too far.
The Army's Gerber D.E.T. Multi-Plier 600 Blasting Cap Crimper is a good example, in my opinion. It pretty much splits the EOD/sapper community in half, as well. Like you (and I), some guys love them, some guys hate them. I think they look like one of those wisecracking little characters in Transformers, they are just as prickly, and I would rather carry a small kit with a few more handles than deal with them. Others revere the all-in-oneness.
