Amazon Basics Classic 8-inch Full Tang High Carbon Stainless Steel Chef's Knife, Multipurpose Kitchen Knife with Three Rivets, Silver

You just need 1-3 knives. Do not need to be fancy. I have one I got for sale on amazon for $4 a few years back that works fine. Something like this is a really good all purpose one https://www.amazon.com/Amazon-Basics-Classic-Chefs-Rivets/dp/B09WW6VGHX/ref=sr_1_1 You do not need anything name brand. Yes those are nice, but not required.
