This double-sided portable diamond sharpening stone is clean and convenient. You can use water as a lubricant or use nothing at all making sharpening on the stage mess-free.
The red surface is a fine grit for most double reed sharpening applications. The green extra-fine side is an even finer grit for ultra finishing work on oboe and bassoon knives.
The convenient plastic handles flip open to provide stability when in use, then close to cover the sharpener when traveling.
It has a lifetime guarantee from the manufacturer and instructions included.
Measure 4″ x 1″.
