This specimen is the "non-takedown" version which means it cannot be easily disassembled for cleaning.  Condition is good, with sharpening to the blade, partially obscuring the SMF logo.  Grip wood is undamaged, but does have a stain on the obverse (see photos).  The piece functions, but is a little "tight" (could use some lubricant in the blade well to restore smooth "gravity" function.  Numbered under the finger trigger.
