Thanks for the nice comments fellas!
Tin, Welcome to the forums. Those are hamon that you are seeing. All these blades were quenched with clay on them, then polished and etched.
Brian, Right now I just dont have the time to do a tutorial, but I would be happy to explain how I do the guards. As far as I know Joe does them starting with the handle(which is how I did the first one in the pic)...I usually start with the blade(preform) then start to shape the handle a bit. I might use a round bar, fuller, or horn of the anvil to start the finger notch area. Once I have it deep enough I then clamp the blade in the vise point down...close to the finger guard area....(I'm not telling you when I take a heat...I figure you will know when you need one)...I tend to "tip" the handle portion of the bar back out of the way a bit...then I go to town with a cross pien of a smaller hammer on the finger guard area...straight down towards the tip. This goes on for a bit till it starts looking like what I want. Making sure not to push too much metal to one side or the other. You can straighten it out a bit over the hardy hole...then straighten the spine in a vise. Then I will forge the rest of the blade...then cut it off the bar and finish the handle.
I hope that helps.
Mace
