Aloha and welcome kbrouwer,
Okay, after reading this was for the Scouts, I had to change my mind. I got experience with all three, but I have the luxury of a CF Stretch gifted to me by The Deacon. (Thanks Paul!)
I say go Delica. Economical, ergonomical, fits about every hand comfortably.
I *was* going to say Native, as the wide blade when used with the choil allows some great cutting. That being said though, it's that same feature that causes people to either like it...or not.
Stretch...The Deac' sent this one to me to make me a "believer" in it.
I can now honestly say, "I believe! I believe!
" Great ergo's this one has...however, it might be viewed as "too big" still.
