I have no problem with really small blades, maybe a little I guess when I have another knife with me anyway. I downsized to the Vic Small Tinker (84mm) and it's blade is about as small as I want to go for day to day stuff. Sure the blade on the Squirt is about the size of a utility knife blade, but it is not as handy to hold and get at to use as far as I'm concerned. The Squirt is a very handy tool and I love it, but I carry a knife too. The Squirt is a small pliers with other tools including a blade, and a Vic SAK is a knife with other tools.... your choice.
Part of the utility of a pocket knife is the size in your hand and how it allows you to apply force to cut something. It is not just the length of the blade, it's the overall package for cutting. You have to hold it in your hand to use it.
Why do some people prefer fixed bladed knives? The answer is obvious, because the blade does not pivot to close it, it is stronger and often the handle is much more comfortable to use than a folder. The pivot is the weak link in a folding knife and locking or non-locking blades are about safety. No body wants to have a knife blade close on their fingers. Pay attention and it usually does not happen unless you are stabbing stuff.
Pocket knives are about convenience. The Leatherman Ps4 Squirt is about convenience. It is not the perfect knife, but it works in a pinch. I just prefer to carry a folding knife. I generally do not want to carry a fixed bladed knife in an urban situation. But if more people did it, I could easily condition myself to carry a small fixed blade in an urban setting daily.
Probably need to think about this topic some more because deep down I would really prefer to carry a small fixed blade as a second knife with a small SAK in my pocket.
As far as choosing SAK vs Squirt, I think it depends on the SAK size you choose. There is no question that I would choose the Squirt over a Vic Classic (58mm I think). So, a decision along this line depends entirely to what knives you might already carry and what you routinely do with knives.
