The blade is made of nickel-plated Grover washers, the blade hardness is less than 65HRC and greater than 60HRC. I carburized the blade, not shown in the video, and tempered at 250C, twice. The lock screw is made of a broken part. Has a similar pattern to the blade. My original design was an integral support with a wooden handle, unfortunately, the blade broke off. Broken by me the wrong way. I will also try and learn new things. I've actually tried three new projects in the past two months, only to fail. But I learned something new. Thanks for watching.
