Hello. I recently buyed a Tokyo Spike. Its reference is 53NHS. Taking a look on the catalogues of the brand, I see that reference in Tokyo spikes from 2013, 2014 and 2015 catalogues. Catalogues from 2016 and 2017, named it as 53NHSZ, and specify a sub-zero cryo HT. Catalogues from 2018 to 2022 name the knife again as 53NHS, without "Z", though they specify the same heat treatment, with cryo. So, How can I know if the knife is having that HT? I mean. My reference is 53NHS. Is there a way to distinguish if it is from 2013-2015 or 2018-2022? Maybe trough the box, bar code, QR code... I add some pictures.
Thank you so much in advance.

I believe your box is a latest one 2018-2021.
 
In the gallery of catalogs on the Cold Steel website you can see that they started using the Anytime/Anywhere logo with a tanto blade from 2015 to 2020. Prior to that it had always been the original Worlds Strongest Sharpest Knives design. 2021 to 2022 they began use of the GSM designed logo, Anytime Anywhere with a clip point blade between the COLD(/STEEL. While there was some overlap of logos each time they made a change you can get an idea of what time period your knife was produced.
 
Thanks so much to all of you. I've been comparing boxes and logos and I think is a "modern" one, yes.
English is not my native language. It took me a while to catch it, insta9ves :D
