Watch an Old Rusty Knife Get Restored to Perfection

I have a confession: In my spare time, I like to watch knife restoration videos in the background.

It may sound odd but there’s something satisfying about taking a knife from a rust-covered dull piece of steel to a functional work of art.

Now, millions of people know how I feel.

If you’ve been on YouTube in the past week or have visited any knife sites, you’ve undoubtedly seen the top-trending video from Jun Yoshizuki about restoring a $3 knife to its previous $100 state.

Watch with awe.

I saw this video shortly after it came out and it has now garnered more than 11 million views as of posting.

Jun, who is a YouTube personality and chef,  is known for making videos with his American wife Rachel about their experiences with Japanese culture. (He’s also known for making videos with his cat Kohaku in the background.)

On his own YouTube channel, his previous videos also garnered a few million views (including his second most popular video, which also deals with knives) so this isn’t necessarily a rags to riches story, but it’s always cool to see a knife-centric video get some love from the wider Internet.

As a bonus, here are a few great knife restoration videos that may not have the production or entertainment value of Jun’s video but are still just as satisfying.

For example, here is the slow but loving process of restoring a deba knife (which traditionally feature a chisel grind).

I also enjoy a good broken tip repair video, like this one from The Late Boy Scout:
