The treatment of the grooveless area near the spine may be similar, but I don't see what else? THe blade shape is quite different, as is the bolster, which on Conogre's appears to be made of iron(?) and to serve as a functional ferule.
The small "blade" sounds like a fire striker.
Interestingly, what I've heard is tjhat the flat pointy knife-blade-shaped pockets twice as wide as the two normal side-blade pockets, on the backs of some sheaths is a wallet for spices, drugs, etc. Tobacco is usually cited.
The decorative lines, which may be referential to panel welded steel, appear to be chiseled, rather than etched, etc., and look to have been thru at least one fairly serious after market polishing, or perhaps a series of routine ones.
BTW, gald you like it
