Knife structual terminology is a subject that I am not very familiar with. A quick internet search helps to temporarily take care of this problem (I then forget what I learned fairly quickly). Previously I have saved a couple or so pictures with the various parts labeled. Today I did another internet search and found an impressive site that is quite detailed on knife anatomy. I have not checked it out closely yet to see what all it has. The fellow is a knife maker. As stated, I have not checked it out closely. Thought I would share the link.
