It's always been tough to immediately have a ruler in hand while we want to use it with a craft knife. At least we have to spend some time searching for the ruler on a pretty much messy desk. What about combining the utilities of rulers and knife, making them into one?
Rulerback Knife is a craft knife with a ruler on the back. Whenever people want to use it, just turn the knife back around and we shall no longer need to find a ruler that could possibly waste our time and loosen our concentration for creations.
