Verify that the knife is a genuine Swiss Army knife. Swiss Army knives are usually easy to spot: Look for the Victorinox "cross" logo or (on military-issue knives) the coat of arms of Switzerland. However, these identifiers could have come off or been removed from a genuine knife or the knife could have one of the symbols but still be a fraud, so it is best to get the verification of a knowledgeable, trustworthy knife collector or antique appraiser.
Look at the physical characteristics of your knife: color, shape and blade style/count. The knives have had only a handful of makeovers throughout the company's history, possibly because aesthetics weren't a top priority. Still, during its over-100-year run, the knife has made a few noteworthy changes.
Review the following to get a starting point to making an estimation on your knife's age: The original 1891 model was brown and about 4 inches long. A reproduction was made recently. The Swiss Army knife was not "spring-loaded" until 1897--that was the first red-handled model. The spring is what enables it to have multiple tools on each side.
Because the knife's designs have varied so little, to learn of the knife's precise age it will take more than just comparing descriptions of the knives to your own.
Contact an appraiser if you the knife piques your curiosity, and you are willing to invest more time and energy into the tool. You could find a local antique shop that specializes in tools or photograph it and email an appraiser on the net. Many appraisers will do this for free, but there also are professionals that charge a fee of about $5 or $10.
