Swiss Army Knives by Size
Victorinox Swiss Army Knives range from compact keychain companions to robust field tools, and finding the right size is the first step toward choosing the right model. With over 300 Swiss Army Knives in stock, DLT Trading organizes our selection by frame length so you can quickly narrow down your options based on how you plan to carry and use your knife.
Understanding Swiss Army Knife Sizing
The size designation on a Swiss Army Knife refers to the closed handle length when all tools are folded away. This measurement determines not only how the knife carries in your pocket or on your keyring, but also the blade length and the overall tool capacity. Larger frames accommodate more tool layers, longer blades, and in some cases, locking mechanisms that smaller models lack.
58mm Swiss Army Knives
The 58mm platform is the standard for keychains. These compact models slip onto a key ring without adding noticeable bulk, making them genuinely disappear into daily carry. The Classic SD is the most recognized knife in this category, offering a small blade, scissors, nail file, and screwdriver in a package light enough to forget you're carrying it. If you want basic cutting capability and a few essential tools without any pocket commitment, start here.
84mm Swiss Army Knives
The 84mm size occupies a middle ground that appeals to users who want more blade than a keychain model provides but prefer something slimmer than the standard 91mm. Most 84mm models include both a large blade with a 52mm cutting edge and a smaller secondary blade. Specialty variants like the Electrician include purpose-built tools for specific trades. This size tends to carry well in a coin pocket or small pouch.
91mm Swiss Army Knives
This is the size most people picture when they think of a Swiss Army Knife. The 91mm platform has the widest variety of tool configurations in the entire Victorinox lineup, ranging from slim two-layer models to the thick Swiss Champ with its 15 layers of implements. The main blade measures approximately 60mm with a non-locking slip joint design. Models like the Tinker, Spartan, Huntsman, and Fieldmaster all build on this frame, each offering different tool combinations to match specific needs. Whether you want a corkscrew or a Phillips screwdriver, scissors or a wood saw, pliers or a fish scaler, there's a 91mm configuration that fits.
111mm Swiss Army Knives
When you need a working blade with serious cutting capability, the 111mm models deliver. These large-frame knives feature blades over three inches long, and most incorporate a liner lock or slide lock to secure the blade during heavier tasks. The Hunter, One-Handed Trekker, and Farmer X are popular choices for outdoor use where you need to process wood, prepare game, or handle chores that would strain a smaller knife. The trade-off is pocket bulk—many users prefer a belt sheath or pack storage for 111mm models.
130mm Swiss Army Knives
The 130mm frame represents the largest Swiss Army Knives Victorinox produces. Originally developed under the Wenger brand before Victorinox acquired the company in 2005, these models continue under the Victorinox Delémont line. The Ranger Grip series exemplifies what this size offers: a substantial locking blade, ergonomic handles with textured grip zones, and tool selections oriented toward outdoor work. These are not pocket knives in the traditional sense—they're field tools designed for serious cutting tasks where grip security and blade length matter more than compact carry.
Choosing Your Size
Your ideal Swiss Army Knife size depends on how you'll carry it and what you expect it to do. Keychain users who want emergency capability gravitate toward 58mm. Daily carry with real utility often lands at 91mm. Dedicated outdoor and work use typically calls for 111mm or 130mm frames with locking blades.
