Every time I go to cut food, I always get annoyed by the hand opening. I’m not always handling the board so much to need a hand hold. It’s always laying flat. The only time I need the hand hold is when I pick it up.
Then today, I realized … it’s a melee weapon.
My board is wider than the can. But I’m not sure about “that’s what the whole is for”. My board has a round hole like for a thumb. I find it useful for hanging it up to dry, after cleaning.
