Crystal Thayer Rana Katana High Quality -

The consensus among dedicated forums like BladeForums and r/SWORDS is that refers to Thayer’s "Wound Series" – a set of five katanas, each representing a different type of battle injury (Laceration, Puncture, Crush, Burn, and Frostbite). The "Rana Katana" is specifically the Frostbite variant, which pairs the crystal-infused steel with a cryogenic tempering process that leaves the blade a pale, ice-blue-grey.
