I have seen a couple other knives with RMK handles on them, but as is stated in the letter above, very few. That being said, all seems good save for the "blood etching" statement. I throw a flag on that. Probably even fewer "knife fight" blades with blood on them exist than non-Randall blades with Randall handles.
SOG knives were notorious for rusting and pitting as the steel was not the best particularly with the fact that they were very inexpensive and the climate and conditions in which they were used.
Interesting piece for sure.
