All three are USA-made CPM MagnaCut DuraLock 3.13-inch reverse tanto raw aluminum Bel Air folders. The 6105RAWBLK at $160 has a black blade finish — most carry-neutral, no PVD coating, subdued dark-over-silver two-tone, $40 less than the PVD variants. The 6105RAWBLU Cryo Raw at $200 has Blue PVD coating and Cryo heat treatment — cool blue-over-silver, Cryo-optimized MagnaCut microstructure, PVD surface hardness, $40 more. The 6105RAWGLD Aurum Raw at $200 has Gold PVD coating and Cryo heat treatment — warm gold-over-silver, Cryo-optimized MagnaCut, PVD surface hardness, $40 more. Same raw aluminum DuraLock USA-made platform; choose black for carry neutrality at $160; choose Blue or Gold PVD for Cryo treatment and PVD color at $40 more.

The 6105RAWBLK at $160 delivers identical CPM MagnaCut reverse tanto raw aluminum DuraLock USA-made performance as the $200 Cryo Raw and Aurum Raw without the Cryo heat treatment or PVD coating premium. Buyers who carry the raw aluminum Bel Air as a functional daily carry piece rather than a collector configuration will find the black blade's carry neutrality suits any carry context without color-specific visual associations — and save $40 in the process. The Cryo treatment adds optimized MagnaCut microstructure; the PVD adds surface hardness and vivid color. For buyers who want raw aluminum Bel Air carry at the most accessible price without PVD color preference, the 6105RAWBLK is the right configuration.

Verify the exact black blade finish specification from your distributor data before publishing — the specific coating type (black oxide, DLC, PVD black, or Cerakote) affects durability claims and care recommendations. The finish is listed as black in the product specification but the specific coating chemistry should be confirmed before making durability or hardness claims in the product listing.

Raw aluminum is machined aluminum without any anodizing, coating, or surface treatment applied — the natural unfinished metal surface showing aluminum's characteristic warm silver character. Anodized aluminum receives an electrochemical treatment that converts the surface into a hard oxide layer, adding color (black, white, gold, blue) and surface hardness. Raw aluminum's natural surface shows tooling marks and has a premium industrial aesthetic without the color uniformity of anodized finishes. Raw aluminum will develop a natural patina and wear marks over time — an authentic industrial carry character that some buyers prefer over coated or anodized surfaces.
