My son at 18 used my rotary cutter on my ironing board cover. He thought it was a pizza cutter - like that makes a difference! :thumbdown:
I think it is really up to their maturity. Obviously my son and his friend were not mature enough to use it. I think when he saw me slice the tip of my finger off was his wake up call. He now is very careful and does not use it on my ironing board or pizza.. 8-)
