Case has become the undisputed favorite of knife collectors for a variety of reasons including the rich heritage, quality and variety of knives. However, the Case dating system also adds to the appeal and collectibility because the knives can be easily identified and dated. Case has been marking its knives with tang stamps from the beginning. The markings below show which tangs where used and when.
