I just bought a Kershaw Blur tanto folder, model 1670TBLKST on the Bay today. I looked up the material info, it is supposed to be Sandvik 14C28N. However, there is a Walmart page claiming the steel is 440A (https://www.walmart.com/ip/Kershaw-Blur-Folder-440A-Stainless-Tanto-Blade-6061-T6-Anodized-Aluminum/16935204). Does Kershaw make lesser-steel version for Walmart stores? Can anyone confirm? Seller claimed new old stock, but the box has 1670TBLKST WM on it, which prompted me to think it would be a Walmart knife.
