I'm happy with the design and now I've traced it onto the steel and have begun to remove stock with my angle grinder (4" metal cutting wheel). This can be done with a hacksaw or Jeweler's Saw also. I'm going about it slow as not to overheat the steel.
I'm staying outside of my lines to be on the cautious side. After I get the rough shape I can clean up the profile with the angle grinder or bench grinder... and then a Mill File. There are many ways to remove stock and get the profile. I'm just using what tools I have available to me.

The Nessmuck design is coming along well. I cleaned up the edges with my bench grinder and am currently removing the natural pitting of the steel with my belt sander (mounted vertically).


Meanwhile, the Chef knife is almost done. Here is the rough handle scales attached and pinned (brass pins, peened). I'm about to take it to the belt sander for shaping.

I have a little time today so I've begun to hand-file a bevel on the Nessmuck. This may take some time. I'm not going to put a sharpening edge on it... that will be done AFTER heat treating, very important. My goal here is to equally establish my bevel on both sides of the profile. I'm going with a tall bevel on this knife to increase it's 'slicing' ability. A short bevel would lend itself more to a 'chopping' edge.

I'm still hand-filing the first bevel on the Nessmuck.... starting to look more like a knife now.

I have finished the Santoku Chef Knife. Now you can see how the black handle spacers look... I think they added a nice touch. Racing stripes so it can chop and slice faster! slaphead.gif

Thanks Denise! That knife was fast and easy.
Nessy, on the other hand.... difficult. Stock removal is laborious with hand files but coming along well.
I'm almost finished with my second bevel. whew.gif If I mess it up after all this work, I'm going to cry.
I am getting the bevel lines, cutting edge, and ricassos to match. thumbsupsmileyanim.gif

Thanks Jim!
I'm happy to say that I've completed both primary bevels now on the Nessmuk. I think the hard part is done. They are currently sanded down to about #320. I've decided that the original handle tang I designed was too big and here I have redesigned it. I will reshape it using the bench grinder (possibly cutting disc too). I will also have to drill new pin holes to accommodate this design.

The Nessmuk (I just realized I've been spelling it wrong... correct spelling of the name is ..."muk") is now ready to be sent off for heat treat/hardening. The company I'm sending it to only does heat-treating once a week on Mondays so it'll be a couple of weeks before I get it back.
Once it comes back I will install the handle scales (maybe stabilized Black Ash Burl for this one), polish/buff all exposed steel, then file a secondary cutting edge into it and sharpen. It will be complete except for sheath. I intend to learn sheath-making soon so that this one has a nice little custom home to sleep in.

Here's what it looks like now after I reshaped the tang and drilled new pin holes. The cutting edge is very blunt and a little thicker than a dime. Anything thinner would be damaged during the heat-treatment, very important! I also engraved my name and other info (where it will not be seen) as requested by the company that will be performing the heat-treat. The heat-treat service costs $5.50 for this knife and I opted for Cryogenic cooling for an additional $4.00. The Cryo process will add durability and increase edge-retention. Basically they will heat this puppy to somewhere around 2500 degrees, then cool it in a Cryo tank which is about -300.
