I have sold hundreds of forks in the last few years and it amazes me that not even one single person has ever asked me how to sharpen the tines if they start getting blunt. Being made of wood the tips may get a little frayed after much use so I designed my forks so, with very little effort, they can be kept sharp almost forever without changing their shape. Being flat on top but curved toward the point on the bottom and sides makes it easy to keep them spiffed up by occasionally sanding the curved parts and not sanding the top or inside of the tines.

How To Sharpen A Wooden Fork
Below are a few pictures that show how to sharpen our forks. If the tips aren't as sharp as you want them to be because they have frayed from use you should first use fingernail clippers to snip off just a little of the frayed tips. Then lay a piece of medium sandpaper on a hard flat surface like a table or counter. Hold the paper down and hold your fork kind of like in the picture and start pushing the fork back and forth longways and rocking it side to side as you sand it from the point back towards the handle over and over. Don't sand it any more than is necessary to get it as sharp as you want it. Finally use a piece of fine sandpaper in your hand to make it really smooth. You're trying to keep it the same shape as when you started. What happens is in taking off just a silly millimeter from the sides and bottom it brings the points back to a sharpened state again without changing the fork's shape.
