I think I'm old enough... do you?

The kids have all been helping out building the new bedroom. Todd has taught them how to use several tools for the job (under supervision and ability appropriate).  The boys have used Todd's pocket knife a lot - opening up boxes and whatever else a pocket knife is useful for.  They have been taking turns carrying it in their pockets.  The other day, when we were at Menard's, Garrett was walking beside Todd and looked up at him and said, "If you think I am old enough to handle it, I think they have pocket knives here."
