I have my little buddy after carrying all sizes over the years. It's now a Case XX Limited Edition Peanut, green/yellow stag. 2 7/8" closed, two blades. Good for about anything except killing large mammals. It's handy for anything I need it for and does a job on my leftovers for lunch at work. Small enough not to weigh down my pocket. She's 10 years and aging well, plus I don't go anywhere without her.
Mine is greenish/yellow, not lime green like the stock picture.
