Important Read :

The ring implement provides an optimized draw, deploy, and control feature to the end of the handle.

The combo of a hardened stainless blade with a 7075-T6 Aluminum handle provides a tough throwable PocketSai for practice, training, and EDC at a reduced cost. A blade made in 440A martensitic stainless steel with a hardness of HRC 40-45 makes a tough resilient stainless made for throwing and can take extreme abuse offering bending where harder alloys will break.
