Over the course of Case’s long history, literally hundreds of different knife patterns have been created. To help our collectors identify the various patterns, we developed a unique numbering system. What kind of Case do you own? You can find the Case knife pattern number stamped on the tang of your knife’s blade. This number tells you exactly what kind of knife you have. The first number indicates the type of material used to make the handle. The second digit gives the number of blades. The last two or more digits indicate the factory pattern number.
