Sale
$129.95 $139.00

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 HARDENED STAINLESS STEEL Blade and a Composite Polymer Handle

Phenix- the blazing phenix rises from the ashes every 500 years. Artwork Inspired by the WWK Women's knife throwing league event in 2022.

Hybrid SS-Poly Thrower (Trainer) - The combo of a hardened stainless blade with a Polymer handle provides a tough throwable Pocket Sai for practice and training at a reduced cost. A blade made in 440A high carbon martensitic stainless steel with a hardness of HRC37-40 makes a tough resilient stainless made for throwing and can take extreme abuse offering bending where harder alloys will break. This combination is a notable upgrade from the Full Polymer trainer.

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.
