    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.

          I loved it so much that less than 2 weeks after receiving it. I've already bought another one to add to my collection

          I'm thrilled you are enjoying your PocketSai! It was the original D-Series design, hence 'D1' all others were evolutionary changes and alternative applications.
          Thank you so much for your support
