I carry close to $100 in various places when out and about - also credit cards, multitool (or two to three).Also change
Like you, I carry 2 or 3 multitools of different designs in some of my kits. One advantage is that each type offers some tools that are not available in the other MT. Like one MT has a hammer head, one has a better screwdriver. Or sometimes you just need two pairs of pliers together.
Sorry, back to cash.
There is a roll of coins in the car for parking. But will only carry paper cash on person.
