Prepare your wasabi per package instructions.
Put your sauces in their little containers and prepare to slice rolls.
Grab a roll and put it on your cutting surface.
Pull your Excalibur knife from it's ice water stone.
Slice your roll in half to make 2 four inch rolls. It is important to NOT saw your rolls but to use a SHARP knife to cut in one slicing motion.
Now turn 1 half of the roll so it is along side the other half. You should be able to get 3 cuts out of the two halves so that each roll gives 8 pieces.
Eat it how you like it. Enjoy spending $15 dollars and getting 6 or 7 rolls. Or go out and drop $6 to $12 dollars per roll at a sushi joint.
