Wth bro? The whole point of the video is making the sharpest knife... yet you didn't finish sharpening it?

[thepathofplayfulness]

Didn't know ruby was so high on the hardness scale! Also, I think myself and other people would've preferred to see the sharpness test in this video, but very cool project!

Sweet a ruby scalpel! I heard surgeons use obsidian knives sometimes, but I’ve never seen an a ruby one.

There’s a standardised sharpness tester called the Bess sharpness tester. It measures how many grams of force it takes to cut a standardised filament.

I've dreamed about someone making a blade from these synthetic sapphire half-boules since they started making them! Absolutely amazing project!

[PartyButler]

Dude I was so excited when you mentioned this in your last video! Im totally adding this on my random project list!

First time viewer. Your fingers are terribly close to spinning dismemberment. Have you considered work-holding so your second most precious hotdogs can continue to grip your first most precious hotdog to their fullest?

[bioboi]

wow, that turned out better than I expected.

[SylisisCluttered]
