A cutter is widely used because it is more convenient than knives. But you can feel uncomfortable, when you want to cut something accurately.
I think of the intuitional advice, which can cut something with the exact length with ease, through this inconvenience.
A smart cutter shows a length of the object on the digital display. It can show it with PIR Sensor, attached on the front of it.
Now, you don’t need to read the gradation on a ruler, when you cut something. You can cut something with the exact length, if you have something, which can replace the ruler.
