I'm trying to nail down the Fortune knife's relationship to other earlier and later Schrade models. I've read every post I can find regarding these knives but none have included the exact length of the knife. Schrade made 3 similar but different "sleeveboard lobster" variations that I can find. They were 2-5/16", 2-3/4" and 3". What size is the Fortune knife? I'll be very grateful to any and all who take the time to check for me.
