Greg,
The .450 completely slipped my mind. That should be good medicine for close range encounters. (God forbid) Are you, or have you considered, using cast bullets? I seem to recall us discussing this in the thread in Community a while back, but refresh my memory.
The HKR I have has a 9" polished blade. It came with a camo Kydex sheath and smooth burgundy Micarta scales. I remember Newt mentioning in a thread some time ago on his forum, that this is one of the early incarnations. The heft of it certainly gives one a feeling of security. The one I have definitely isn't a slicer.

It has been sharpened so many times that it would need some significant reprofiling. Mine is a 1/4 inch blade and has stamped on one side, 95, and on the other side, Newt Livesay and 5C. It also has Rapid Deployment stamped on the main portion of the blade. I think Newt might have changed the newer ones to 3/16 though. You would want to carry a smaller knife (or from what I've read in your past posts, three or four smaller knives

) for slicing. This HKR definitely has been used. That's what I like about it though. Knowing it has been around the world on military ops adds to it's character. I got it from Chad234. That's what he liked about it too.
On another note, my brother and his family are up in Alaska as we speak. How is the weather up there? (That's probably a silly question. Alaska being so big, it's kind of like asking, "How's the weather in the middle portion of the country?") He is a Doctor and is being recruited by a couple towns. This is his second all expenses paid trip up there in the last two months. The lucky dog!

ps- All this talk about the HKR has me pumped up to use it. I have an 8" tree that is dead in my back yard. I was going to use my RTAK to fell it, but I think I'll use the ol' HKR.
