Which knife/multitool for mountaineering

I was wondering if you guys had some advices for a new knife/multitool for mountaineering.
Gave mine away this weekend to the hut warden to thank him for all the good tips and tricks about the route we were about to climb. 

I was using, for the past 4 years, a Leatherman Crunch.

What I liked: 
The locking pliers to tweak mountaineering gear (crampons, bolds, around the hut etc..)
The sharp knife to cut cordelette and everything else you may need to cut on a route
The file for crampons and ice tools sharpening on the spot
The screwdrivers for stove and crampons maintenance and much more
The lanyard hole to keep it clipped to my harness

What I didn't like:
The weight
The faff to access the blades (impossible with gloves on for ex)

I could certainly live without the file and just use a piece of rock for crude filing on the spot. Maybe a Leatherman Skeleton would work...

I m wondering if I should just buy a new Crunch or if there is something better out there.
Any idea?
What are you using and why?

I just tape a razor blade to the inside of my helmet..

lol, not bad, certainly an ultralight option, did you learn that watching a prison documentary ;) ?

Look at Leatherman Squirt PS4. The file probably sucks for use on crampons but certainly better than a rock...

I don’t really see the need for pliers (esp. locking ones). If you can live without, there are plenty of options. You could get one of their pocket tools that has multiple size hex slots for bolt and crampon work

True that I could do without locking pliers, but I do use pliers all the time. For example last weekend I used it to closed shut the window in our room that was broken in the open position (chilly ;)). I also use it many time to tighten bolds since I also take it in multiptch sport climb. Also true that I could bring a dedicated tool but pliers are just more versatile.

The Squirt PS4  looks like a much lighter option indeed, thanks for the suggestion!

I have a Leatherman Juice S2, they don't make them anymore but they're easy to find on eBay. It's light and compact for having pliers which I find key for winter stuff (unsticking frozen locking carabiners, sled repairs etc..) but if I don't think that is very likely (eg day trip) I just carry a good old Opinel #6 with a small hole drilled in the handle for a cord loop. I find the Opinel reasonably easy to handle with gloves on, you can smack the butt of the handle to get the tip of the blade to stick out. 

Some TSA dudes have about a half dozen of my Juice S2’s.  Rat bastards 

Two other light options below (smaller is a Gerber curve)

If just for cutting, I prefer the Skeletool.... light as is, but can make even lighter if you remove the clip/bottle opener off the back

I have some Squirts as well but mainly leave in vehicles for the odd use.  I think in general all the items are too small to be really effective   

Thanks for all your ideas!
The Opinel is great but mountaineering I often need more than just a blade, I do have one for hiking, wicked sharp!

I ll go with a Leatherman Skeleton this time. 

Skeleton is good if you just need a knife. Otherwise, I carry a leatherman Sidekick with me at all times. The thing is a brick but can do everything you need, short of building a particle accelerator.

At the end I checked the Skeleton and I thought the pliers were too weak for my taste, went with a new Crunch instead.
I really think they could be a market opportunity for a tool geared toward mountaineering, I would quite like to see:

Something as lightweight as possible with a clip for the harness

With 4 tools:
1/ Reasonably strong non-locking pliers (stronger than the Skeleton)
2/ The main blade would be serrated and open with one hand
3/ Replacable file (such as the one on the Surge) just a coarse version, no need for a diamond one
One big flat screwdriver (could be the tip of the file)
4/ One medium size flat screwdriver (with rounded corners could do double duty for Phillips screws)

I guess I am basically asking for a mix between a Crunch and a Skeleton
If someone around here is working at Leatherman ... :)
