Get the Medium if you want a snug fit with an Arc.

"There’s about a half inch of play between the top of my Arc to the flap when closed. Leatherman recommends a large but my medium is a better fit. Not a dealbreaker as it doesn’t really shift much but worth mentioning as I would have gone with a medium in the first place if I had known. It’s easier to pull out with a medium sized sheath. Gave it 4 stars because of this. The sheath has held up to daily use at work (only 2 months so far but still looks new). Good quality nylon, just wish their description was more accurate."

Too small and too tall

"I bought the large sheath in midnight. Three things: 1. It is too tight for the ARC. It’s hard to get the knife in/out of the sheath. 2. The sheath is too tall - hardly any of the knife is proud of the top lip. Combined with the tightness, it makes getting a finger hold on the knife very difficult to pull out. 3. I ordered midnight which I assumed was black - it was a dark blue. The quality of the sheath and the stitching is great."

It's a Sheath

"It's a sheath, it does what it should. The snap is rock solid and I don't worry about loosing the tool. I like the orange color for farm use (so I don't misplace it)."

Rock Solid

"Sturdy and easy to carry. Wish it was a little easier to retrieve smaller tools out of, but otherwise, great carrier."

Good sheath

"Like it better than the leather ones. Velcro models lose their closing ability. My last nylon sheath lasted about 4 years, then the sides ripped out causing me to temporarily lose my Surge Tool."

Not fond of the color

"Through it was. Brown was more baby poo green. My mistake picking this color"

Forever

"My Leatherman is with me again. When my original case failed, I quit having my buddy with me. I almost always found that something came up that required its use. I feel “whole” again"

Rides a little high for me
