Why it’s important to sharpen the Santoku knife regularly?

Regular sharpening also helps to extend the lifespan of your knife. Over time, the blade of a knife will naturally become dull due to regular use. If you continue to use a dull knife, it can cause damage to the blade over time and make it more difficult to sharpen in the future.

One common technique is using a sharpening stone, which involves rubbing the edge of the blade against a rough surface to create a sharp edge. Another popular option is using a honing rod, which is a long, cylindrical tool that can be used to hone and realign the blade’s edge. 

Some factors to consider when choosing a sharpening tool include the type of blade being sharpened, its size and shape, and the desired level of sharpness. 

Ultimately, selecting the right tool and technique will depend on individual preferences and needs.
