There's a certain kind of carry magic that happens when you slide something into your pocket and forget it's there. Not because you've forgotten it's there - but because it's genuinely hard to make something this thin work this well. Shaving every unnecessary millimetre without touching the soul of the knife isn't a design brief, it's a high-wire act. And the makers pulling it off right now? They're sticking the landing.
That's what the slim knife category is doing right now, and it's genuinely exciting.
We've dug out our slimmest knives in the warehouse, and we're going from the thickest of the slimmest all the way down to the kind of thin that makes you do a double-take. Consider this your countdown.
CIVIVI KUKEI - 10MM | THE 5TH POCKET OVERACHIEVER
At 10mm thick and just 7cm folded, the Kukei looks like it belongs in a shirt pocket before it looks like a knife - which is sometimes exactly the point.
But don't let the compact frame fool you. This thing was designed by Tashi Bharucha, the same mind behind some genuinely premium high-end knife designs (his WE Knife OAO collab is worth looking at if you want to see where his head usually lives).
The front-flip action is one of the snappiest and most satisfying we've handled - it flicks open effortlessly. The 2.5mm blade thickness keeps it nimble, and at 7cm folded, it genuinely doesn't look like a knife at all until it very much is. Slips right into the pocket.
CIVIVI SLIPPY SENDY - JUST SHY OF 10MM | THE SLIPJOINT YOU REACH FOR
Ben Petersen's Civivi Sendy won awards. Then Civivi took the design and turned it into a slipjoint, which opens it up to carries and places where a locking blade doesn't belong. Just shy of 10mm overall, with Cedar G10 ($92) or Ultem scales ($108), the Slippy Sendy is finished very well by Civivi and feels more premium than the price suggests. The Ultem version comes in at 39g - ultralight carry.
The pull on this one is light and approachable which is genuinely underrated as a feature. This is the knife you confidently hand to your mate on a bushwalk when they need to slice an apple and have never held a folding knife in their life. No white knuckles, no nervous energy, just clean fruit and a good time.
BIGIDESIGN OVERLOOK - 9.5MM | OUR OFFICE KNIFE OF 2025
We're not shy about it: this one's an office favourite. BigIDesign's The Overlook ($359) is a compact Titanium framelock at 9.5mm thick, and the action is what sets it apart. That ceramic ball detent interface you usually only find on much more expensive knives? It's here. It's smooth, it's tactile, it's the kind of thing you fidget with across a full workday without realising.
Our customers have given it nothing but 5 stars, and we're down to our last one. Genuinely, one left. We'll have more incoming soon on our next order but if you want one now, don't say we didn't warn you.
VOSTEED RACCOON TISLIM - 8MM | THE SECOND CHAPTER
Vosteed clearly liked where the Parallel went, so they kept the momentum going with the Raccoon TiSlim. It's their second in their slim lineup of knives. Same axis lock mechanism, but this one's got a drop point blade and beautifully milled titanium scales that feel considered, not just machined-down.
At 76g and only 8mm overall, it's still a full 3.18" blade. The 2.2mm blade stock keeps it slicing rather than wedging. The milling on the handles is the kind of detail you notice the longer you carry it.
VOSTEED PARALLEL — 7MM | THE ONE THAT STARTED IT ALL
Seven millimetres. That's it. Stack three 50-cent coins on top of each other - that's how thick this knife is. You genuinely have to hold it to believe it. The Parallel (from $206) was Vosteed's first crack at a slim knife, and they absolutely nailed the brief. Full-sized folder. Titanium handles. Reverse tanto blade. 2mm of blade stock, ground to cut, not to fill out a spec sheet. The axis lock is slick and confident, and the titanium scales keep the weight down to match the profile.
It sounds like a compromise on paper. In the pocket, it just feels like someone finally did the maths right.
TACTILE KNIFE CO. BEXAR — 7MM (AND CHANGE) | THE THINNEST THING IN THE ROOM
Made in the USA. The Bexar (From $279) is named after a county in Texas. The X is silent - it's Bear. And once you hold it, the name makes sense, because this thing is almost shockingly thin in hand. No pocket clip (it's a slipjoint), so nothing interrupts the profile. Closed, it's a perfectly thin piece of titanium or G10 that disappears into your hand. At 34g in the G10 base version with MagnaCut steel, it's punching well above its weight class which is impressive considering it barely has one.
The pull sits in the medium-strong territory, which is actually part of the charm — this is a knife that rewards a little familiarity. Give it a week and it'll feel like second nature; it's just asking you to get to know it first. Think of it less as a barrier and more as the knife's way of saying "we're not doing casual here." We've sold out of the Titanium version (51g, also MagnaCut — still a bargain), but more are incoming. We've got a customer buying a set for their groomsmen right now, and honestly? As far as gifts that'll outlast the wedding, it's hard to argue with a USA-made MagnaCut slipjoint in titanium. Practically an heirloom that also opens boxes.
SPECIAL MENTION: SENCUT TEXO & CIVIVI CIRCULUS - THE FEATHERWEIGHTS
We couldn't wrap this countdown without a nod to two knives that are playing an entirely different game.
The Sencut Texo ($52) and Civivi Circulus ($102) are skeletonised fixed blades designed by the very talented Ostap Hel. The Texo tips the scales at a genuinely absurd 19 grams with a blade only 3mm thick in 9Cr18MoV steel. That's lighter than most people's car keys. The Circulus steps it up a notch in 10Cr15CoMoV steel, and neither one will bulk out a boot, a pack strap, or a neck lanyard.
These aren't your traditional EDC folders, but if you're heading out on a bushwalk and want something fixed, fast, and practically weightless? These two earn their place on the list. Neck knife, boot knife, "just in case I need to slice something on a trail" knife.
Ostap Hel designs tend to have a signature look that minimalist, functional yet aesthetic and these are no different. Highly wearable, surprisingly capable, and at those price points, an easy yes.
COMING SOON: VOSTEED PORCUPINE TISLIM
Vosteed's slim series keeps going, and the next chapter is the Porcupine TiSlim — their first slim release with a top liner lock rather than the clutch lock on the Parallel and Raccoon. It's not trying to match the Parallel for outright thinness, but it brings a different lock geometry and a different carry feel. Available in 154CM or premium S90V, with an acid wash handle that gives it real character on the shelf and in the pocket.
The product pages are already live and you can start wishlisting right now — go ahead, treat yourself. But as always, our newsletter crew hears about arrivals first. So if you're not signed up yet, the time is very much now.
Porcupine TiSlim drops Thursday 16th April @ 7pm AEST @ Adventure Carry.

The Overlook was my favourite knife of 2025. I’ve backed their latest knife, Ti Manu on Kickstarter. I’ll definitely be getting one of the Porcupine TiSlim models.
