Absolutely! I bought a heavy duty paper cutter off eBay for less than $100. Just search for heavy duty paper cutter or guillotine paper cutter. They have a huge clamp and mine came with an extra blade. One of the best investments I've ever made.

Came here to say the same thing. I printed and bound a couple of books using the very instructions from this site back in the early 2000's. I tried to trim one of the books myself with the "chisel method" and I was displeased with how it turned out. The one that I had a buddy cut with a guillotine paper cutter at his workplace was much, much more pleasing.
