ErgoSharp by DH Cubed

Take the Guesswork Out of Sharpening


ErgoSharp by DH Cubed, is a small electronic device that attaches to any sharpening stone and lights up when the stone angle is 110 degrees. 

Why does it light up at 110 degrees? This is the optimal angle for the sharpest dental hygiene instruments with the least ergonomic strain on the body.

This is why we named it ErgoSharp, it's innovative sharpening and unprecedented ergonomic feedback in one.

  • Achieve consistent sharpness on curettes and scaling instruments.
  • Quickly maintain a sharp edge chairside, in seconds.
  • See in real time where 110 degrees is, no guessing involved!
  • Reduce the strain on fingers, hands, and wrists.
  • Eliminate the root causes of pain, instead of treating it.

This device is the cornerstone of our ErgoSharp Sharpening System which was created as a culmination of 30 years of dental hygiene clinical and training experience. ErgoSharp is easy to master and designed for everyday use.

Light On = Instant Feedback!
