My Mom's birthday was several weeks ago on the 4th so I decided to make my mom a knife for her birthday. I couldn't help but make myself one as well.
First time really trying a knife with thin starting stock (0.090") and basically my first real attempt at properly making a knife after my razor making experience. The steel is 52100 which was a first for me as well in working with it.
I decided to make some Japanese style petty knives and aimed for about 155-160 mm for mine and 170mm for my moms.
Here are some pics of the blades after hardening and tempering. The top blade still has the scale on and the bottle has been ground to near finish. The handles are rough shaped and ready for hand sanding. Stabilized poplar burl/blue & black recon stone spacer and buffalo horn ferule on the top handle (moms). Stabilized walnut burl/yellow & Black recon stone spacer/ and buffalo horn ferule on the bottom handle (mine).
I aimed for a concave grind and thought it went pretty well for my first attempt at this with the concave grind extending 1/2-2/3 of the way up the blade.
Unfortunately on grinding my blade I got too thin towards the toe area and lost some of the profile. I finished off the blades with a forced mustard patina to protect them a little.
My knife looks a little better than the pics shown for the profile as I've shaped it a bit on a bester 1200 sharpening stone. Regardless, I actually left the edge at that level for mine and it preforms excellent - it is all I've been using for the past several weeks. My moms I took up to 3 um lapping film, but I actually think I like the toothier edge of mine better for use.
Really happy with how they came out. I stamped my mark a little too deep on both of them thinking I better leave room for the post heat treat grind. Someday, when I make stuff again I'll remember to not stamp so deep. Eventually I would rather get an electro-etch makers mark as it is just so much easier to deal with.
My mom loved hers and has been using it a lot as well.
