Im not really doing any camping, its just for peace of mind that if i need it ill have it.
If you're not camping, I assume that you're going to be doing some hiking, or something close to hiking. If that's the case, then the question of peace of mind can work at a couple of levels.
I keep a daypack with a minimal survival/emergency kit in it in my car and this pack or its contents go with me on any hike. The survival/emergency kit I carry is based on the Mountaineer's "10 Essentials" list. To my way of thinking, "peace of mind" comes from having this list covered and having knowledge of how to use them.

FWIW, Harvey Manning, the original author of the 10 essentials list, wrote the following in the 2nd edition of Freedom of the Hills as he advocated the use of a boy-scout style utility knife (aka SAK).
"For special purposes a hunting knife is superior, as are double-bitted axes, cavalry sabers, Gatling guns, and dynamite, but a modest mountaineer contents himself with a modest blade."
In this light, your Leatherman alone is enough, as would your SAK (although I prefer having pliers for repairs).
At another level, peace of mind might be carrying more stuff (more clothing, more extra water, more knife) because you are afraid of the consequences if you don't. Here you get into a tension between bringing things that bring comfort and the comfort of your pack as the weight grows. This can lead to a 40lb day pack. There is a great saying on this... "We carry our fears in our pack."
And yet another level of peace of mind is fun. If you like to carry a knife just to play with a knife then peace of mind will only be achieved by bringing that knife or those knives so you don't miss an opportunity to play with them. That's entirely reasonable.
If you don't plan on hiking and you don't plan on camping, then I would suggest carrying whatever you typically EDC.
