This UPK-D4 Eclipse is made in 100% HARDENED STAINLESS STEEL

A minimal guard version of the Pocket Sai. The guards have been reduced to provide the optimal amount of grip for blade retraction.

Optimized for throwing and melee impact, made in 440A high carbon martensitic stainless steel with a hardness of HRC: 45 makes a tough resilient stainless. It can take extreme abuse and offer a point of bending where harder alloys will break, making this ideal for throwing when the worst abuse takes place.

  • EDC Defensive Implement

Important Reads:

Double edged vs Un-edged : ordering a double edged version will be completed in 48 hours with a edge grind that is brought to 1000grit wet silicone carbide and polished.

Optimized material for throwing, this implementation was done in 440A, a high carbon martensitic stainless with a reduced carbon content then its 440B and 440C relatives, this makes a tougher resilient stainless in exchange for reduced hardness. Heat Treated to HRC 40-45 these are still harder then most the objects around you, but will take extreme abuse and offer a point of bending where harder alloys will break, making this ideal for extreme impacts and the worst abuse.
