OMG Nostalgia for me here. Back in the late 1960's hubbie won an electric knive. Gave us a wonderful feeling of modernity when we used it, with a flourish when we had guests!!!!
Of course, back in those days we always had a joint of meat each Sunday!!! Usually leg of lamb. Think, these days, I would need a second mortgage to purchase one of those!!!!
Cannot think I would have use for one these days, no joints of meat, sliced bread usually purchased. Anyway, so much easier to have really good quality sharp knives now, and easy to use sharpeners.
