Well, still I got no Knipex like here shown, but possibly some other pliers from that brand. Sure, I got some monkey wrenches, very small ones and a very big one , for some operations. But I am not convinced yet about having it on the bike, too bulky on many places. I prefer real spanners in correct sizes - but then, when you look for monkey wrenches on YT in clips from US or UK, you can find them in workshops for good reasons. I guess mechanics see a big need for adjustable wrenches for dealing with funny head sizes of all sorts of "standards" in the imperial world - actually a small world today, mostly US plus Liberia and Myanmar remaining.
