@bruces I'm a big fan of the One Tool for One Job idea, until I actually try to do something. Then it's "What's on hand that will get the job done?"
There are also the innumerable "I need a second $tool for the job" situations.
Multitools are great for being the available 2nd tool, even if technically it's the 1st tool and your other multitool is the the 3rd one. (The other, other one is busy being a 500 A slow blow fuse)
