Cattaraugus 225Q, with original sheath. (I also have a modern replica sheath which I use for the knife instead of the old veteran.)
Although in great shape, the handle on this one no longer shows deep, heavy scoring on the center section, which was apparently part of Catt's manufacturing process, presumably to provide a better grip on a wet or slippery handle.
Also, a previous owner rounded the corners of the last steel disk in the butt, rather like what Buck did to the bolsters of the 110 and 112 some years back.
Some folks put a mirror finish on Catt 225Q blades because they weren't issued as subdued or Parkerized. But I'm leaving this as-is aside from normal sharpening for use.
