Hidden Features Of Everyday Items

Utility Knife

As most people own a box cutter or utility knife, you probably noticed some of their design features, such as the thick plastic cap at the end or the little score lines between the blades. Well, as it turns out, these features aren't only an aesthetic choice but have a purpose to them. The score lines show where exactly to break off the blade for a new, sharper blade, while the plastic cap is removable and can be used to cut off the blade.
