Keeping a good sharp edge on your fillet knife is very important. A blunt knife will not only make the task of cleaning your catch difficult and time consuming but it is also dangerous. With a dull edge you will be inclined to push harder to make the knife work thus increasing the chance of slipping and causing injury. The Jarvis Walker Deluxe Knife sharpener is the ideal tool to combat dull knife edges. Compact in size and convenient to use, this tool should be carried with you and used regularly to maintain a consistent sharp edge.
