EDC brandTortoise Gearwants to fix that. Its new Lamprey91 pocket clip is universally compatible with virtually every 91-mm Swiss knife model from Victorinox, and it's arguably the most elegant solution to this problem anyone's cooked up.
Fun fact: Victorinoxacquired its rival Wengersome 20 years ago, so it's now the sole supplier of Swiss Army Knives to the actual Swiss army. In 2020, it wasreportedly producing 45,000 knives a day.
Lamprey91 | The ULTIMATE pocket clip for your 91mm SAK!
Tortoise Gear says it's spent years going through dozens of prototypes to create the Lamprey91. It's designed to be installed in seconds without tools or modifications to your multitool, and seamlessly integrate with every hidden rivet Victorinox model in the immensely popular 91 mm size.
The Lamprey91 utilizes the knife's internal geometry to wedge and clip securely to the rivets. This makes for a neat fit that makes it look like your multitool came with it out of the factory, and ensures it stays put once fitted.
What's especially nice about this accessory is that it can be installed as a removable or permanent addition, thanks to the inclusion of locking tabs that can be bent before fitting to keep the clip attached for good.
The clip is made from high quality aerospace-grade stainless steel, engineered to maintain a strong grip where it clamps on to your pocket, and is heat treated for strength. Since it attaches at the back top of the knife, it doesn't interfere with any folding tools, and doesn't occupy the keyring like some other clips.
There are a couple of addition clever bits to this design too: the clip has room at the top for a lanyard. That makes it even easier to whip out your knife when you need it. Plus, the clip can hold a 4-mm bit and double as a screwdriver in a pinch.
Tortoise Gear is crowdfunding the Lamprey91 on Kickstarter, where you can get one for US$25 (down from its expected $29.99 MSRP), made in the USA.
All crowdfunding campaigns carry an element of risk, so you'll want to keep that in mind if you choose to back this campaign. That said, Tortoise Gear is a licensed accessory maker for Victorinox products, and haspreviously shipped a thoughtfully designed fire steel and tinderthat fits into the knife's toothpick slot, among other products.
If all goes to plan, orders are slated to ship worldwide in February 2027, and delivery costs will be calculated once the campaign ends (estimated at $5 for US orders, and about $15 for international orders).
