this makes my head hurt trying to understand

So many things wrong with this, the "peanut butter and jelly bagel knife":

First, WTF?

Here's the BB&B item description:

Bagel knife has river-shaped grooves to hold peanut butter, jelly, cream cheese or even regular butter unto the knife. With the extra long handle and tool, you don't need to worry about your hands or fingers getting messy. There's even a serrated edge to easily slice through the bread. Ergonomic handle has the Orthopedic Research Institute Seal of Approval. Dishwasher safe.

So the river shaped grooves hold the peanut butter (etc.)? Doesn't a regular butter knife also do that? And then can't you wipe the knife clean on the side of the bread once it is spread to your satisfaction? How do you get all the peanut butter out of the river grooves?

I don't get it - can anyone explain?

Also, the ergonomic handle (!) and the Orthopedic Research Institute seal of approval? Again I say - WTF?

Here's the ORI mission statement (it makes my head hurt even more):

Development

Application of engineering methods, techniques, and procedures to the solution of problems in clinical orthopaedics; resulting in new devices, systems, materials, and procedures. Further, the application of biocompatibility testing using cutting edge in vitro and in vivo model systems to enhance safety assessments

Research
Applied research in the laboratory and in clinical settings to enhance the understanding of orthopaedic-musculoskeletal diseases, their prevention, diagnosis, and treatment. Also, pre-clinical evaluation of pharmaceutical drgus and biological response modifiers for the treatment of arthritis and bone disease

Am I to assume that there had been previous orthopedic issues with the billions of PB&J sandwiches that have been made since the dawn of PB&J? Is this why I see people with those velcro wrist support bands?



Seriously, I DO NOT understand this product.
