Here's a quote by Ernest Emerson that I pulled of another Forum regarding the "myth" that serrations can catch somewhat. Now if I'm not mistaken, don't you prefer a straight edge due to tendancy of serrations to get hung up on clothing?
Always - always, carry a knife with serrations. That is an internet myth that I wish would go away. Think of hitting something with the force of a baseball swing. Serrations do not hang up on anything. Never did. Never will.
