I'm getting bags for Christmas and will be putting some kits together. One will be a Med kit that I will take with me when I travel and attend classes, the other will be a road bag for when I go out of town for work. I'd like to get a knife to leave in each bag. I EDC a Zero Tolerance 350 and a Kershaw Chive so the new knife would be backup or get used if I didn't have my EDC knives. These will see normal cutting chores. The one in the med kit would open bandage, cut guaze, etc. The other would open boxes and packaging, just normal day to day activities. I'd like a blade in the 2-4" range probably around 3". One hand opening with a lock. Prefer made in the US not concerned with blade or handle material. I'd like stay in the $20-$40 range but want a decent knife not a flea market special. Any suggestions?
