"If you cut every corner, it is really not so bad
Everybody does it, even mom and dad."
This song, featured on The Simpsons, was about doing a poor job. The song can also be interpreted so that it's about cutting things. As such, the song would be correct. Cutting things is not so bad.
In fact, cutting things is great.
As far as knives go, I've got no complaints about my Victorinox Swiss Army Knife. It has the perfect balance, sharp blades, and some extremely useful scissors. At first, I laughed at the knife for having scissors, but over the years I've found that I use them more than anything else on the knife.
