This pencil sharpener is so quiet - it does make a tiny amount of noise, but nothing compared to the annoying sound that my electric one makes. I could easily still teach a lesson and this be used at the same time. It has a crank handle, but it doesn't need to be drilled down to a table because of a special clamp. It was easy to put together and sturdy - all you have to do is just place the clamp into the little hole and it's done. I didn't even need to ask my husband to put it together, I could handle it myself.
