Sharpening a $1 knife

Sharpening a $1 knife

►Sharpeners I use in this video (Amazon affiliates links)

※These sharpeners seem to be sold more expensively outside of Japan. I believe you can find cheaper ones that are decent online as well. Zwilling J.A. Henckels also has good sharpening stones which I have used before. Unlike the ones I used in this video, you don’t need to soak it in water to sharpen a knife (but it still needs to be wet).

Sharpening stones come in grits, and these two grits would be enough for a normal household knife. I used grits 1,000, 2,000, 5,000, 8,000, and 12,000 in this video. The higher the number, the finer the sanding and the sharper the knife will be.

    Wow! I’ve been sharpening my kitchen knifes for a while, but I could never
    get them to that degree. I’m only using one stone though. But now I think,
    I gotta up my game, buy some more stones and get to water bottle samurai
    sharpening skill level 🙂

    by the way, the most annoying things to cut with a dull knife are lamb,
    beef and tomatoes in my opinion :)

    My edge doesnt last very long when i sharpen, I must spend over an hour
    carefully sharpening it. Must be my angle, seeing this i need to try again.

    Your music from the video is mislabeled, fam. It’s not ‘Redwood Trail by
    Audionautix.’ The song used in this one is ‘Behind Closed Doors by Otis
    McDonald.’ #SaveHila

    The key to getting views or popularity on YouTube is not clickbait,
    thumbnails or other stuff. The real key is: CATS

    Have a CAT in your video & you’ll gets lots & lots of views & LIKES. ?

    “Cats, we can never have enough cats”
