No, it is not recommended to get the toast out of the toaster with a knife. Using a knife to remove toast from a toaster can be dangerous and may result in injury or damage to the toaster.
Toasters are designed with a lever or a mechanism to safely lift the toast out of the toaster when it's done. When the toast is ready, simply use the designated lever or button to pop the toast up.
If the toast gets stuck, always make sure the toaster is unplugged before attempting to remove it. You can use wooden or plastic tongs or a non-metallic utensil to carefully and safely retrieve the toast.
Never use a metal knife or any other metal object to get the toast out of the toaster as it can cause a short circuit or electrical shock, and metal can conduct electricity. Safety should always be a priority when using kitchen appliances.
