I don't want to be " heavy" on this.. but give me a break: better grip on a SAK? not relevant with the can opener, the scissors,the bottle cap lifter, the nails file,the awl... for the blade or the saw? I am not going to chop wood for the fire or build a log cabin with this thing ..
IMHO, a waste in design and manufacturing efforts for a feature that is marginal at best - My guess is that their sales dept were either bored or they just lack creative imagination.

To be fair, I am a fan of Wengers- got the fisrt one back in 1974 and now my "flag SAK" is still a Wenger (their can opener is a masterpiece of engineering)- They are sturdy, elegant, useful and well built. That thing with the new "ergoscales" I see as a dumb sales exercise- I prefer pocket knives with the plainscales. Nothing special needed to make a knife with the "natural grip"
