More Angles / Eraser

More Angles

More angles divides a complete eraser into several pieces, which linked with each other by shallow grooves. Each piece has 6 angles. Once all angles on a piece are worn that makes it not convenient to use any more, we can fracture the eraser by the shallow grooves and start to use the new piece. In a word, More angles enhances the utilization by providing us with more angles.
The center part of an eraser is seldom used which is removed in more angles. In this way, it saves materials and makes it easier to fracture.
