Have you looked at the Outrider?

I say that alox is better because you can get dirt and gunk stuck under celidor and nylon scales.
I'll try to help. As far as durability of the Soldier for the money is very durable and we'll handle most tasks with no problem just remember it's a folding knife and it's not going to preform as well as a fixed blade at tasks like batoning. The 70 30 serrated blade is a great utility blade and should handle most outdoor tasks.It's week points would be it's not the best at wood carving and it wouldn't be my first choice for dressing game. If you're dressing game and can't use a fixed blade I would recommend a plane edge One Hand Trailmaster.Assuming that Rifle scope screws are the same as here in the States the SD well fit it fine.I'll sum up my feeling on the Soldier like this. If I where in a "survival situation"I would feel very happy about having my Vic Soldier with me.
I'm not a hunter, but the 111mm series are great outdoors/survival knives. Can't testify to how well suited for skinning/gutting etc.If you measure the width of the screws on your firearm I would be happy to measure the screwdriver on any size SAK for you. But the 111 has the biggest of the drivers, so I'd guess it isn't too small, but could be too wide.
