Thinking out loud, the Model 1 is the same basic blade, and you get a double hilt at no extra cost on it--if you want a "combat" or "fighting" knife. And if for some reason you don't want the Top Edge Sharpened, just ask the shop not to sharpen it, or if you already have the knife then dull it yourself on a large flat stone.

Anyway--I have a Model 1-5 that blade- and hilt-wise looks a lot like the above Model 5.
