Favorite wrench to climb with that meets likely bolt/nut sizes

I know that metolius or someone makes a nut tool without about 4 sizes of nut wrench but it is a bit hard to get at many nuts with this gizmo (have to insert thru bolt hanger to get at some nuts so lucky to get 1/16th or 1/32nd turn). Not keen on carrying around a 6-inch crescent wrench for size & weight.
I am sure many of you also run into the occaisional loose nut that would be nice to give a quarter turn so bolt hanger doesnt spin/move.
Have scoured hardware stores, but i dont see much. I have some small bicycle multitools but they dont cover the bigger nut sizes encoubtered in climbing.
Would be nice to have something in little pocket of my chalk bag

The smallest size Vise Grip. Great tools.

It’s adjustable. Part of my standard ‘sport rack’. Weighs as much as a quick draw. 

of these two choices, i definitely prefer the vice grip. and, I HAVE ONE! This is one of the very few posts I have seen on here that is actually helpful to me, so thanks!

I set a few routes.  I moan a bit when after a few years and traffic somebody grumbles about a spinner.  Good on you all above for carrying a wrench.  If you know the area/route setter, you can lighten up with a open end wrench that has two different sized ends and that you have bent in the middle to avoid knuckle bashing.

I use one of these that is 1/2" on one end and 9/16 on the other which will work for most 3/8 inch and 1/2 inch bolts commonly used in the US. It's very lightweight and easy to clip on with a carabiner.

I like this idea, especially the offset, but the 1/2 to 9/16 must be 8 inches long at least. Maybe i could use cutoff saw & cut in half & take some length out too. Still seems kludgy.

Since i dont plan to crank on the bolts but snug them up a bit i would think there would be a lightweight solution, something like the metolius nut tool but with those 2 sizes on each end of flat 5 to 6 inch max piece of steel.

Peter, I just keep one in my pack for maintenance at our local Crags so a little extra weight is not a concern while I'm climbing.

Ah, the ol' tumb-detecting nut fucker. Perfect for rounding off those pesky corners.

Yeah, adjustable wrenches are not really good for anything except quicklinks...I have the knuckle scars as proof. It's also hard to set wedge or sleeve bolts with an adjustable wrench...the nuts round off/knuckle skin is shredded before you ever get it tight enough. Get a 9/16"x1/2" closed-end offset wrench (saves the knuckles) and you'll be good to go for most typical nuts.

I don't climb with a tool box on my harness.  I keep the tools in my backpack and if something needs tightening I finger tighten it and will come back later with a wrench.

What size is this that you use? Previous poster said 1/2" and 9/16" worked the best for most bolts found in the US.

I do carry a crunch in my backpack, could fit on a harness with a leash.

Visegrip

Knife

Frozen screw gate and rusty quicklink opener

Beer opener

All in one

Which part opens a rusty quicklink? Vise grip?

Exactly. Get the offset kind as in photo, the more the better, and your knuckles will think you (especially on granite)
