Versa58 Pen Scale
Add a Pen to Your 58mm Swiss Army Knife
Your 58mm Swiss Army Knife handles cutting, filing, and opening. Now it writes too. The Versa58 Pen Scale adds a slide-out ballpoint pen with a premium German Troika refill. It snaps on in seconds and removes just as easily. No glue. No grinding. No permanent modification. Compatible with 58mm Swiss Army Knives with Cellidor (plastic) scales. Not compatible with Alox models.
Versa58 Pen Scale: What You Need to Know
Is this compatible with my Swiss Army Knife?
Yes. Compatible with 58mm Swiss Army Knives with Cellidor (plastic) scales, including Classic SD, Rally, Jetsetter, Rambler, Midnite Manager, and MiniChamp. Not compatible with Alox models.
Will this damage my Swiss Army Knife?
No. The scale attaches to the existing brass rivets without altering the knife’s chassis, tools, or frame.
Is it reversible?
Yes. The Swiss Army Knife itself is completely unaffected. Original Cellidor scales can be reinstalled, though fit may not be as tight after removal.
What does this replace?
It replaces one stock Cellidor scale with a machined scale that houses a slide-out ballpoint pen. All knife tools remain accessible.
What tools do I need to install it?
None. The Pen Scale snaps directly onto your Swiss Army Knife in under 30 seconds.

Why Upgrade Your 58mm Swiss Army Knife?
Your 58mm Swiss Army Knife is one of the most carried pocket tools in the world, but its configuration is fixed from the factory. Permanent modifications can add capability at the cost of the knife’s integrity. Versa58 gives you a third option: modular scales that snap on and off without tools, adhesive, or risk. Add a pen today, swap to a flashlight tomorrow. Your knife stays intact. Your setup evolves with you.
About the Versa58 Pen Scale
The Versa58 Pen Scale is a machined replacement scale that adds a slide-out ballpoint pen to any compatible 58mm Swiss Army Knife. It uses a premium German-made Troika refill, pre-installed and ready to write out of the box. The pen slides out from the base of the scale, writes smoothly, and tucks back in flush when not in use.
Available in 6061 aluminum or Grade 5 titanium. Both variants are precision-machined, weigh 10g, and match the footprint and feel of the 58mm format. The titanium version is more wear-resistant with a distinct matte finish. The aluminum version offers the same functionality at a lower price point.
No tools, no adhesive, no modification. Snap it on, snap it off.
Beyond the Swiss Army Knife
The Versa58 Pen Scale also works as a standalone tool with a MagMount, sold separately. Pair it with the Pocket Flare for a two-tool keychain setup: pen and flashlight, no Swiss Army Knife required. Attach it to a keychain, clip it onto a backpack, or keep it on your desk.
