You apparently can use any "slash" weapon to cut a banana. I don't know if this works for any other sliceable item, I tried with logs and a pineapple that I happened to have and it didn't.
is 1ticking karambwans really that rare? i noticed the bot buster guy was shocked by it. but its the meta training method on the wiki for cooking and Ive never seen a 99 cooking guide that doesn’t recommend it
