I bought a piece of 1.5 inch stiff foam to try to fix a sag in a bed. It didn’t work but having that thick piece of solid foam around has been a life saver.
Need something flat to put a laptop on? Throw it on the foam. Going to be doing something that requires you to be on your knees for a while? Get the foam!
It went from stupid purchase to something I’d gladly replace if it broke.
Pizza Scissors. Great for frozen pizzas so you can cut it up right out of the oven without waiting for the cheese to cool off. It’s also great for cutting dough and just having a 2nd pair of kitchen shears if your normal pair was used to cut raw meat.
Big chefs knife is what I use for pizza. Though having a couple sets of scissors around wouldn’t be a bad idea.
