This is beneficial for several reasons Which I will succinctly outline below:
1. Saves the environment bc you don’t have to use water.
2. Saves time so you can look at your phone longer.
3. Introduces subsequence users of the knife to bacteria and germs that won’t kill them but will probably strengthen their immunity maybe
4. If anyone happens to see you pull this stunt they may think twice about coming over and eating all of yr bread
