Wow, those look great. Homebrewn?
Please tell a bit more - steel, treatment, grind, spine thickness, stock shape...
I started out with some 1.5" x 12" x .125" 1080 steel billets. This stuff still had the mill scale on it which kinda sucked. I just bought some from a different supplier that comes ground so I don't have that crap! 1080 is easy for me to heat treat so I'm sticking with it for now. I brought the temp up to non-magnetic, then gave it another minute or so. I don't have any Parks 50 so I'm stuck with canola oil heated to 130 deg for my quench. I do two, two hour tempers at 400 deg.
I bring my edge down to about .03" before I heat treat, then down to about .01 before sharpening. I might need to go a bit thinner but it's just so easy to jack up your temper when doing your final grinding. I'm using a angle grinder to cut out the rough shape, bench grinder to get it closer, and a cheap 4x36 with ceramic belts for everything else. It's just a wing it garage hobby that I'm really enjoying right now.
