Turn A 2€ Rusty Knife Into High-End Japanese Chef's Knife

I found this big knife at a local flea market in a bucket of "everything 2€" miscellaneous items. I bought it with the intent of lightly restoring it but after a close inspection I thought I was better off doing something more interesting with it since the construction was pretty bad, with un-even grinds, terrible pins and poor materials. After removing the rust I could also tell it has pretty much no historical value since it has no marking at all. So here we go! In this video I go through the entire process of turning it into a better looking (and better performing of course) chef's knife. The design is pretty close to a kiritsuke, but it's much bigger than most measuring 43cm (17inch) overall with 30cm (12inch) blade 6.5cm (2.6inch) wide and 2.5mm (0.1inch) thick. I tried to develop an hamon on the blade for aesthetic reason but without success, maybe the steel is not prone to show it since the harness is definitely different from spine to edge before and after tempering. Or maybe some other reason, I didn't wanted to spend the time to figure that out anyway. I had also another issue with the heat treatment where the refractory cement expanded and got stuck in the blade holder inside the oven, I had to quench everything... Yeah... That wasn't pretty at all! The handle is made of iroko and ebony wood, with a mild stainless steel guard and some red felt and white paper liners, the process of making the spacers is better described in this video:    • Felt And Resin Liner / Spacers DIY   I just started to list some of the stuff I use for my projects in this amazon storefront: https://www.amazon.com/shop/blackbear...
