It's hard to describe, but I have a very macho, bad ass grip on tools and heavy things I have to move. I used to be very strong when I was young and out squeezed many people in "handshaking contests" regularly. I've always done a lot of gardening and using a shovel makes for strong hands.
But, I also have days of sensitivity in my extremities. When I have itchy, tingly, fuzzy days I don't really want to touch anything or be touched. Those are the days when I drop almost everything I pick up. It is very common for me to misjudge how much grip I'm using at these times.
I also have broken many glasses by hand washing ... not from dropping, but from putting my hands inside with a sponge and it just breaks. It's hard for me to judge how much force I use at times.
I don't know how you could put any of that into a simple question.
Clumsiness, lack of focus on menial tasks, ease of distraction during tasks, oh yeah ... I drop stuff.
