Navaja Knife Case Hardened: blue gem pattern guide

Nobody respects the Navaja until they see #398: roughly 98% blue overall, playside AND backside, handle to tip - arguably the cleanest Case Hardened roll in the game, achievable only because the blade is tiny. The ultimate stealth flex on the ultimate budget knife.
HOW THE PATTERN WORKS
Case Hardened is one big mottled texture of blue, purple and gold patina; the pattern index (0-1000) rolled when the item drops picks which slice of it lands on the model. Blue occupies the smallest share of that texture, so a seed that lands heavy blue on the side you actually see - the playside - is the rare one. The blue never fades with wear: float adds scratches and darkens the golds, but a blue gem stays blue even Battle-Scarred.

WHAT COUNTS ON THIS ITEM
The small blade means full-blue-both-sides is actually possible here, which no big knife can claim. Tiering still ranks the playside first.
