A butter knife that works straight from the fridge? I'm in!
I don't eat much spread or butter type stuff. I have toast about once a week and I'm not a huge sandwich fan. So when I do, I like to have proper butter. The frustration is that as an infrequent butter consumer, my butter is always in the fridge and completely solid. Nic once experimented with warming the butter on top of the toaster. Do not do that.
Take my money fellas, I've needed one of these bad boys my whole entire life.
