Pocket Sai Trainer
This version of the UPK-D1 Pocket Sai was created and optimized in 50% Glass Filled Nylon made to 100% scale and fully functional. This material is impressively tough and rigid. This is the same type of polymer used in handgun frames and quite sturdy. To optimize the product for this material the blade gained fluted ridges to improve stiffness through geometry. The handle threads are brass inserts to further improve strength.
If you are curious how the Pocket Sai works or just want to get your hands on a low price version to try it out, this is it.
Color
The color of each piece is a unique blend created by mixing a fiery red and ominous black. No two pieces are the same.
Design
Designed from the ground up as an implementation of the Okinawan Sai, a defensive melee weapon that would be practical to carry and sheath itself. The Handle slides to eclipse the blade's edges and point, and makes an integrated sheath. It's one-button locking mechanism is designed to engage in the open or closed position, and must me pressed to unlock it from either end.
Traditional inspiration
The original Okinawan Sai is a defensive melee weapon optimized for non-lethal techniques used by Okinawan police to control and subdue, noting that the saki(point) or yoku(prongs) offer pointed tips that would be used when a more lethal need arose. I chose to shape the monouchi(main blade) of the Pocket Sai with beveled edges that draw to a point at its end giving it a more ominous look and a more effective tip for its compact size. The bevels enhance a more focused contact pressure on soft targets and provide improved piercing with the saki. In respect to the traditional Sai, the Pocket Sai is pointed without live edges, this provides better resilience to weapon on weapon impact in melee control techniques.
Fabrication and Finish
Injection mold- a fabrication process, forcing the 50% glass filled nylon using the immense pressure of a screw compressor creates a temperature to liquify the polymer into a mold shaping the components of the blade and handle.
Matte Finish - the injection mold interprets the surface finish leaving a matte medium/fine granular texture.
