The reason wood needs to be maintained is that wood dries out. Generally speaking, a wooden handle snaps up from a few drops of oil from time to time. Grapeseed oil prevents cracking and increases its resistance to changes in humidity and temperature. In addition, a well-oiled handle looks much nicer because it brings out the markings of the wood much better.
How to use:
Pour a couple of drops of grapeseed oil onto the woorden handle and rub it with a cloth. Allow the handle to absorb the oil freely. Repeat this process until the wood is saturated and won't absorb any more oil.
Why grapeseed oil:
Compared to olive oil and other oils, grapeseed oil sticks and smells significantly less.
