1. I just tried to use the word kniving in a sentence. It looked so weird that I started to doubt whether it was even a real word. Which, of course, it is – but only if you spell it conniving.
2. I had an opportunity to use the word conniving in an email to my boss type person today.
3. You’re more likely to hurt yourself with a dull knife than a sharp one.
