i have a question .im new at this knife making . what is with the arc grinded out below the ricasso .i see a lot of knifes with them . is there a reason for them .i thought they may be used to strike a fire starter in the groove ?
It give you a location to sharpen to. I also believe that when a knife is heat treated the steel expand and if the blade is real thin is will sometimes turn into a sin wave. This cut out area allows the blade room to expand. If anyone else has a reason I would like to hear it.
I have always known the notch to be for sharpening as well as an aesthetic feature, but Cal's expansion theory makes sense as well
