MAKING A PBJ - Knife in PB or J first?

I put it in the peanut butter and spread it on one piece of bread, then if the jelly I have isn't the kind you can just squeeze on the bread, I take the 2nd piece of bread and wipe off the excess peanut butter (to clean off the knife) then 'scoop' the jelly out of the jar and spread it on the 2nd piece.
