Met Jason (Guyon) today, and picked up my first Rat in person- a sterile HRLM. We talked for a bit and he showed me a few other Rats, Busses and sheaths- you know, the kind of stuff that addictions are made of (red meaner street maybe?). Knife has more heft to it than I realized, there is no mistaking that this knife can take pretty much anything I am ever likely to toss at it. Edge seems a bit thicker than what I'm used to, but it is a convex grind. Typically use a sharpmaker on my other knives, may have to try my hand at the mousepad/sandpaper technique (have a bunch of 320, 400, and 2000 grit paper in the basement). If that doesn't work, I don't suppose it's a mortal sin to put the standard sharpmaker bevels on it. Sheath-wise. am torn between leather and kydex- leaning towards one of the standard production models from armoralleather. Not real interested in having to sending the knife out for fitting, hoping they have a patterned sheath for it.
