The extremely fine finish of the honing rod gives an incredible sharpness but thanks to the handle, tip and core all being made of rubber, they're about as close to unbreakable as is possible with ceramic rods.
We've dropped our test sharpener a few times and it's survived so it's great for a busy home or professional kitchen!
This honing rod is approximately 10,000 grit.
Our aim is to measure everything as accurately as possible but some specifications (such as hardness for example) are provided by the manufacturer and therefore should be used as a guide only.
