Woohoo! I usually have to exclude myself from giveaways because I have a rule not to get knives I won't carry (I have to keep this habit under control somehow), and anything bigger than 3 3/8" or so had better be single-spring or a very friendly shape or it won't fit in my coin pocket.
So: Smaller is better because smaller gets carried more, and your tools don't do you any good sitting in a drawer at home.
Thanks for the very generous giveaway!
