I have been waiting for a little while for my Bagwell made Hell's Belle, and having discussed th Ontario model with Bill himself, I do believe I can add a bit of insught here.
The grip is not Kraton b/c a Kraton handle will impede a proper back cut (made with the false edge)as the kraton sticks rather than "snaps" in the hand. The swedge is not razor sharp as it is designed to do other things; a back cut if properly done will take of bits of anatomy even without a razor edge. It acts sort of like an axe blade in this respect.
The handle plate is for determining where the edge is in the dark, shiny or not shiny has no actual relevance per the design as Bill makes this as a concealed carry piece. The sheath is designed to hide inside clothes and therefore any shiny rivets or snaps or whatever wold not be seen in the larger scheme of things.
Rockwell I cannot attest to nor as to finish on the factory versions, but this is a special purpose knife to be sure. Like all edged weapons, it is not made for much else and even Bagwell will tell you this. If I want a camp knife, I will have Bob Schrapp make me a good heavy leather sheath for Trail Master with a pouch or a DMT butterfly sharpener or an EZ LAP rod along the front, but to each his own. I have talked with another (Bram Frank) who was having a kydex break-out rig made for his Hell's Belle so he could carry it in shoulder rig. James Piorek may be the man for you to have do this sort of shoulder harness.
Have a better day.
