How to Make: RAZOR SHARP Knife From a Wrench (Karambit)

My second ever attempt at blacksmithing a knife, today I'm making a Karambit out of a 21mm wrench from home depot, using my:

Homemade anvil:    • Easy, Cheap DIY Anvil for Knife Making! (+...  

And my homemade forge:    • Fold-Away Blacksmith Forge (Satan's Toilet)  

My end product is a little underwhelming, but as long as you use a bigger wrench you should be fine. Special thanks to Chandler Dickinson, whose videos have educated me more than high-school ever did.
