A Katsuobushi block is the (Japanese: 鰹節) is the dried, fermented, and smoked skipjack tuna. It comes in the form of blocks and is often shaved down to make bonito flakes often found in Japanese dishes and dashi.

In America you might have to look to your local Japanese store or sometimes some Chinese stores as well (the larger ones).

The shaver is an essential tool if you’re going to buy your katsuobushi in blocks as you need to use the flakes on your Japanese dishes and in your dashi.

The katsuobushi shaver is called a “Kezuri” and was an essential tool in making bonito flakes after 1670 when the Japanese added mould to the fermentation process.

Using the mould, the fish would be able to be preserved for even longer than before, but it also took out all of the water and fat from the fish, thus making the katsuobushi block as we know it now as hard as stone.

Prior to 1670 a knife would be used to shave down the blocks into shavings for consumption, but after the making process was changed, the specifically designed Kezuri shaver was introduced and became a household item.

You can shave the dried fish block over the top of the shaver like so:
