Its all about the weight to me.

Doug's Mk1 weighs 3.82 oz. Doug's Mk3 weighs 5.7 oz. The LM Wave weighs 8.5 oz. My Charge Ti weighs just a bit less.

I find carrying the weight of the Charge TI on my belt or in-pocket uncomfortable. Doug's knives - even the fixed blade - weigh so much less.

The only LM tool that I might miss in the outdoors is the saw, but I pack a larger Silky Pocketboy folding saw in my pack (not on me).

I have never needed pliars when outdoors - except to remove fish hooks, but if surviving I wouldn't care about that - about killing the fish.

I carry separate small tweezers in my FAK.

Beyond that, I just don't have need for screwdrivers, file, can opener, etc ...
