The founder of Halfmoon is a knife enthusiast with a wide range of blades—from pocket knives to outdoor fixed blades and top-notch chef knives. Keeping them sharp is a must! He started with hand sharpening and then tried various fixed-angle sharpeners, but he found a common issue: most couldn’t maintain a consistent angle. As he sharpened from the blade body to the tip, or switched different thickness sharpening stones, the angle often changed, leading to frustrating adjustments.

So, why didn’t a reliable product exist to solve this?

In 2025, Halfmoon was established, formed a dedicated team to address this challenge. After months of brainstorming and designing and sample testing, halfmoon team created a unique sharpener that automatically adapts to maintain the same angle, making the sharpening process much simpler. This innovation gave birth to the HM1, our "True Precision Knife Sharpener"
