Gone are the days when you need to fold up a loaf of bread and jam it straight down the jelly jar to get that last glob of oh so delicious jelly. That is of course if you have something like this jelly knife. Designed to fit most jelly or peanut butter jar's bottom, this knife is would be a great utensil to have at home.
But we don't think guys would have any use for this. Except of course when the jar in question is one that would rival the Grand Canyon in depth.
