    Important Read:

    The ring implement provides an optimized draw and deploy extension to the end of the handle. The hardened stainless blade with a 7075-T6 Aluminum handle provides a tough throwable PocketSai for practice, training, and EDC. A blade made in 440A high carbon martensitic stainless steel makes a tough resilient blade capable of throwing and taking extreme abuse offering bending where harder alloys will break.
