Inspired by the traditional Okinawan Sai, Pocket Sai are more practical to carry.  When closed the Handle slides to eclipse the blade’s edges and point making an integrated sheath.  It's one-button locking mechanism is designed to engage automatically in the open or closed position and must be pressed to unlock it from either end.

 This version of UPK-D1 Pocket Sai has a Black Hard-coat 7075-T6 Aluminum Blade and Handle

Black Hard-coat 7075-T6 Aluminum - Lightweight Aluminum with steel like strength, the 7075-T6 Tempered Aluminum is one of the strongest Aluminum alloys available with a tensile strength of about 66-70 ksi.  The Hard-coat Anodize provides a resilient protective surface. This material is a notable upgrade from the Glass-filled Polymer.

Traditional Sai- The original Okinawan Sai is a defensive melee weapon optimized for non-lethal techniques used by Okinawan police of feudal Japan to control and subdue, noting that the saki(point) or yoku(prongs) offer pointed tips that could be used for more lethal strikes.  I shaped the monouchi(main blade) of the Pocket Sai with beveled edges that draw to a point giving it a more ominous look and a more effective tip for its compact size.  Like traditional Sai, the Pocket Sai is without live edges, this provides better resilience to weapon-on-weapon impact.
