Patent owned by: Changhe Tech.
Pat. No.:004152015-0001

Product Story:

The concept comes from a Garlic press and  I prefer light and classic, compact products, would like to design a simple sharpener for people, a classic and compact one, I started to draw with a pencil and amended twice then asked the engineer to build the 3D file, after that we made 3D samples and tested, at the 1st 3D sample we found the height is too low for the hand to catch, then we amended the file again and repeat to built a 3D sample and did the testing time and time...
When the first real product comes out, I know that is what I expected,
But for the wheel material, we have been trying almost 2 years and finally, we get the most suitable material for it.
