The Leatherman Arc is the flagship: 20 tools, a CPM MagnaCut blade, and the FREE magnetic architecture that lets every tool open one-handed and lock. At 4.25 inches closed and around 8.6 ounces it is a full-size tool, and the nylon pouch it ships in is the weakest part of the package.
The Arc's magnetic FREE design means the handles are not held shut by friction the way a Wave's are, so the tool needs a sheath that holds it by its shape rather than squeezing it. A molded kydex shell does exactly that: the Arc clicks in, the retention screw sets how firmly, and nothing rubs on the DLC-coated blade or the G10 scales.

| Kydex Sheath for the Leatherman Arc | Kydex | Adjustable | Belt clip; Tek-Lok and MOLLE sold separately | $29.99 |
Fitment
Molded to the Arc only. The Free P4 shares the magnetic architecture but has a different body and its own sheath. Every sheath here is formed on the actual tool, so if your model is a variant, check the dimensions or ask before ordering.
The sheath, reviewed
1. Kydex Sheath for the Leatherman Arc
Molded in kydex to the tool it is named for, handmade in the U.S.A. by military veterans, with adjustable retention and an audible click when the tool seats. Available in black, black carbon fiber, and coyote brown carbon fiber. Guaranteed for life.
How to carry it
On a belt
The sheath ships with the standard Clip & Carry belt clip, which is universal across all our multitool sheaths and carries the tool vertically on a normal belt.
On a duty or work belt
Swap the clip for the Tek-Lok belt clip, which fits belts up to 2.25 inches wide and attaches with the sheath's existing holes.
On a pack, vest or bag
The MOLLE clip replaces the belt clip using the same screws and mounts the sheath to MOLLE webbing on a bag or plate carrier.
Why kydex
Kydex is a thermoformed plastic that is molded directly on the tool, so the sheath holds it by shape rather than by squeezing it. It does not absorb water, oil, or sweat, does not stretch, does not fray at the belt loop, and lets the tool draw with one hand. A retention screw sets how firmly it holds. It is why every sheath here is guaranteed for life.
Sitting, driving and horizontal carry
The reason people stop carrying a multitool is not the sheath's retention, it is the sheath at 4 o'clock digging into a car seat. Two fixes. Move it: 10 or 11 o'clock on the support side keeps it off the seat and reachable by either hand. Turn it: a Tek-Lok mounted sideways makes the sheath horizontal, so the tool lies along the belt and disappears when you sit; the belt-clip version is slimmer for standing days. Set retention so the tool holds upside down and no tighter, and the sheath stays comfortable sitting and driving.
Frequently asked questions
Will a Leatherman Wave sheath fit the Arc?
No. The Arc is longer and a different shape. Use the Arc sheath.
Does the Arc sheath fit the Free P4?
No. The P4 has its own sheath.
Can I carry the Arc on a duty belt?
Yes. Swap the standard belt clip for the Tek-Lok, which fits belts up to 2.25 inches.
Does the sheath scratch the Arc's coating?
No. Kydex is softer than the DLC coating and the sheath is molded to the tool, so nothing drags on the blade.
The bottom line
If you carry the tool daily, the Kydex Sheath for the Leatherman Arc is the upgrade that keeps it on your belt, clicks it in, and outlasts the pouch it came with. Add the Tek-Lok for a duty belt or the MOLLE clip for a pack.
