How to cut books - Guillotine Paper Cutter

I recently purchased the HFS (R) Heavy Duty Guillotine Paper Cutter - 12" Commercial Metal Base A3/A4 Trimmer....................this paper cutter works great for my purposes, you need to take time to align the book and make sure the spine of the book is vertical/straight.
I bought this from amazon, and no, I do not get money from amazon for this demonstration, but thanks for watching. This is a heavy machine, weighs approximately 40lbs. cuts through books like butter.
UPDATE: I used this cutter for 3 months, and it was worth it. I chipped the blade on a staple that was in one of the bindings, but it still cuts stack papter well enough for my needs.

If you are running a professional print shop, then for crying out loud, spend the money, and get a professional automated or semi automated electric paper cutting machine, preferable bladeless (uses a laser instead).
