In addition to what has all ready been recommended, take a look at Buck, Gerber and Kershaw, see below:

Buck 110 $36 - it's a classic

Buck Pathfinder $36 -another classic

Gerber Freeman Caping Knife $32

Gerber Freeman Fixed Blade $37

Kershaw Echo $27 - Excellant buy

Kershaw Vapor - $22 another excellant buy

Becker Necker $30 - love this knife just need to improve the handle

I know you are in scouts and they may not be so accepting of fixed blade knives so the Swiss Army Knives as suggested by Sgt. Mike are good choices and preform well but I still won't venture far with out a good fixed balde to handle the tougher chores.

Right now my favorite combo is the Vic Ranger and Becker Necker w/ Parachord wraped handle.
