For me, the 422. No question about it.
The great entertainment value of threads like this is that people have valid disagreements on what is meant by "backpacking", "hiking", and "woods bumming". People go different places using different techniques and taking different gear.
If I'm "backpacking" or "hiking", I'm in the wet New England woods using leave no trace (or better, leave minimal trace) techniques as described by Harvey Manning (showing my age), Colin Fletcher, and Chris Townsend. For this style of travel, a small multi-function tool is sufficient. The Victorinox Classic is among the most commonly carried knives used by AT thru hikers. My preferred tool is the Leatherman PS4 Squirt, as I find the pliers to be very useful for zipper repairs and for pushing a needle through heavy fabric. I'd recommend a Squirt as a good companion to your 422.
I end up carrying a folder on nearly all trips because... well... because I feel naked without one, really. I've tried a bunch and have my preferences but have settled on the following "must-have" criteria:
- Light weight
- Blade long enough and wide enough at the tip to reach into a jar of peanut butter and spread it (I'm serious about this)
- Light weight
- Handle long thick enough to give my XL hands good comfort when making wood shavings for a fire
- Light weight
Of the two knives you showed, I like the blade shape of the Crosslock better for dealing with food, but in the end, would go with 422 just for simplicity and weight. A 422 with a drop point blade would be a win!!
If you can live with only a Squirt type tool in your pocket (really, this covers about 99% of the realistic backpacking knife needs) and a larger knife in the pack, a lightweight fixed blade makes sense. The Bucklite Max knives are pretty compelling due to their low weight and they make battoning wood a realistic possibility (a very useful tool in New England in some weather). If Buck made a version of the Bucklite Max with a convexed sabre grind, I'd buy 'em by the crate.
I'm leaving tomorrow morning for a 3 night trip with a group of kids. I'm carrying the Squirt and, since we're planning on a fire at least one night (in a location where it is allowed), a fixed blade that is somewhat similar to the Bucklite Max. If the fire wasn't on tap, I would ditch the fixed blade in a second for an even lighter folder in the same size and weight range as your 422.
