Take a look at the Logitech G600. It has 12 side buttons and a shift mode that lets you map 12 more actions to those buttons. It has onboard memory rather than needing a companion app. Linux compatibility is great as it can be programmed with Piper. Only downside is it’s a bit large if you have smaller hands.
Was going to comment about a knife as well but you beat me to it. Though I went with Wusthof. The difference a good knife makes a huge difference for cooking.
The same applies to cookware. Don’t overpay buying a whole set is a waste. Buy the couple pots and pans you need individually and save.
