One of these things are not like the other:
That kind of damage looks like the blades weren't tempered so much as annealed. I can see SOG's low end stainless doing that. And the mystery steel golok is likely that: a mystery.
Get a Tramontina or Imacasa/Condor. Even a Cold Steel. Those are good and durable plain carbon steel. My Trams survive all day pounding and batoning, will bend thirty degrees on a knot, and just spring back to shape.
