UPK-D4 Hybrid Al-Poly
A minimal guard version of the Pocket Sai. The guards have been reduced to minimum amount of grip for blade retraction.
This version of UPK-D4 Bayonet Style has a Black Hard-coat 7075-T6 Aluminum Blade and a Composite Polymer Handle
Hybrid AL-Poly (Trainer)- The combo of a Black Hard-coat 7075-T6 Aluminum blade with a Polymer handle provides a tough Trainer Bayonet for practice and training at a reduced cost. A blade made in 7075-T6 Aluminum makes a tough resilient blade made for tougher tasks then a Polymer blade. This combination is a notable upgrade from the Full Polymer trainer.
