Kizer Quoll Review: The Modular Titanium Frame Lock in Four Inlays

The Kizer Quoll in one paragraph

The Kizer Quoll is a 2.95-inch S45VN titanium frame lock designed by Australian maker Ben Taubert, winner of Kizer's "Kizer x You" design competition. What separates it from the dozens of titanium folders Kizer sells is the handle: the Quoll is built around a modular inlay system, so the same knife can wear rainbow Damascus, crystallized titanium, titanium Damascus, or textured zirconium panels depending on the version you pick — or the panels you swap in later. Four versions are available today at $169.95, $199.95, $219.95, and $299.95, and every one of them shares the same lightweight milled titanium base, the same flat-ground drop point, and the same frame lock.

A knife born from a design contest

Kizer runs an open competition each year where designers submit concepts and the community votes on the winner. Ben Taubert's Quoll took the crown, and it shows: instead of a safe, generic titanium folder, he proposed something personal. The knife is named after the quoll, a small spotted marsupial native to Australia — agile, curious, and increasingly rare in the wild (read about it on Wikipedia). The brief, as Kizer tells it, was to build a knife that feels personal to the owner, and that idea became the Quoll's core feature: a handle you can make your own.

The modular inlay system: the Quoll's party trick

Most titanium knives lock you into one look for life. The Quoll treats the handle like a platform. The milled titanium frame carries an interchangeable inlay panel on the show side, and Kizer sells the same base knife with four different inlay materials so owners can match the knife to their mood — or trade panels with other owners. Kizer frames it as a sharing community: you can collect multiple inlays and swap them freely rather than owning four whole knives.

That design choice has real implications for how the knife feels. Because the titanium frame carries the structure, the inlay is decorative rather than load-bearing, which keeps the Quoll light. The four factory versions weigh between roughly 2.7 and 3.0 ounces depending on the inlay, with the denser Damascus and zirconium panels at the top of that range.

It also makes the Quoll one of the more unusual knives in Kizer's catalog — a production folder with a genuine customization angle, not a paint job. If you are the kind of owner who bonds with a knife over years, or who likes the idea of one well-made frame plus a small collection of swappable faces, this is a feature nobody else at this price point is really offering.

Blade and steel: S45VN in a flat-ground drop point

Every Quoll uses the same blade: a 2.95-inch drop point in CPM-S45VN, flat ground from 0.118-inch stock and hardened to 60-61 HRC. S45VN is Crucible's powder-metallurgy stainless, an evolution of S35VN that raised chromium to around 16% and added a small nitrogen addition for better corrosion resistance while keeping edge retention in the same high-performance family. Knife Steel Nerds' deep dive on S45VN is worth reading if you want the metallurgy; the practical version is that this is a steel that holds an edge well, resists rust easily, and does not punish you at the sharpener the way the highest-wear super-steels do.

The finish depends on the version: the rainbow Damascus and crystallized titanium models carry a satin-brushed or stonewashed blade, while the zirconium and titanium Damascus models pair their darker panels with a matte DLC-Ultra coating. The drop point itself is a versatile everyday shape with a straight-ish belly and a strong tip — equally comfortable slicing open boxes, breaking down packaging, or handling food prep on a camping trip. At under three inches of blade it also sits comfortably inside most legal carry limits, which we dig into in our knife laws explainer.

Opening, action, and lock

The Quoll opens two ways. The primary opener is a titanium thumb disk — a flat, round plate rather than a stud — that gives your thumb a big target for a reliable flick. Secondary is a front flipper tab at the top of the blade tang, useful when you want a slower, controlled deployment or you are wearing gloves. Dual-openers like this are genuinely useful rather than gimmicky: the thumb disk is the fast everyday option and the front flipper doubles as a blade guard of sorts during slow open. If you are new to front flippers, our front flipper vs top flipper guide explains the style, and our guide to telling good action from great covers what to listen and feel for.

Under the hood, the blade rides on caged ceramic ball bearings, which is the configuration we generally recommend for a knife you will open thousands of times — the cage keeps the balls aligned and the ceramic races resist wear and corrosion far better than steel washers or loose bearings. Our pivot bearings explainer compares all the options in detail.

Lockup is a titanium frame lock with a steel lock bar insert. The steel insert is the detail worth caring about: a frame lock is a slice of the handle itself that flexes behind the blade, and if that flexing part is pure titanium it can wear against the blade tang over years of use. The steel insert gives the lockup a harder, more durable contact point, which is a premium touch on a knife that is meant to be carried for a long time. We break down why frame locks behave the way they do in our frame lock vs liner lock comparison.

The four Quoll versions compared

All four Quolls share the same blade and frame; the differences are the inlay material and blade finish.

The crystallized titanium version is the entry point and arguably the best value: $169.95 gets you the full platform with a stonewashed blade and an inlay that sparkles with a geometric, almost gem-like texture under light. The rainbow Damascus version is the most eye-catching of the four — a swirling, multi-color damascus panel against satin gray titanium that dresses the knife up without making it look fragile.

The zirconium version is the stealth pick: a dark, matte-finished panel with a subtle milled texture paired with the DLC-Ultra blade, $219.95. And the titanium Damascus version at $299.95 is the collector's piece — a layered, forged-looking titanium inlay with the same dark DLC blade. If you plan to swap inlays later, all four panels are interchangeable, so there is a real argument for starting with the $169.95 version and adding panels over time. All four are listed on Kizer's official product page if you want to check current stock and bundle pricing.

Carrying the Quoll

Closed, the Quoll measures 4.10 inches and rides at about 2.7 to 3.0 ounces, so it disappears into a jeans pocket without a heavy pull on the waistband. The pocket clip is a milled titanium unit, tip-up and right-hand only, and it is not reversible — lefties will want to hold one first or look at Kizer's ambidextrous models instead. Carry depth is good for a knife at this price: the clip holds the Quoll low in the pocket without screaming for attention. Our pocket carry guide walks through the trade-offs of clip position if you are still figuring out your preference.

Because the frame is milled titanium rather than a heavier steel liner construction, the Quoll never feels like a brick in the pocket — and the swappable inlays mean you can match it to your carry rotation. Compare that with the full-titanium Kizer Militaw, which is a bigger, more formal flagship, or the classic Kizer Gemini, and the Quoll occupies a middle lane: smaller than the Militaw, more customizable than the Gemini, priced between them.

Who is the Quoll for?

Buy the Quoll if you want one premium titanium frame lock that you will actually carry — not a safe queen. The 2.95-inch S45VN blade is a legit everyday cutter, the thumb disk plus front flipper setup is fun to fidget with, and the modular inlay system gives you a reason to keep the knife around for years instead of flipping it for the next release. It is also a great gift for a knife person who already owns the obvious models, precisely because it is not the obvious model.

Skip it if you are strictly budget-focused — Kizer's value line, covered in our Kizer buying guide, gets you a very capable knife for a third of the price — or if you are a lefty who needs a reversible clip. Otherwise, the Quoll is one of the most genuinely original knives Kizer has released this year, and at $169.95 for the base version, the entry ticket is lower than you might expect for a modular titanium folder.

FAQ

What is the Kizer Quoll?

The Kizer Quoll is a 2.95-inch S45VN titanium frame lock folder designed by Ben Taubert, winner of Kizer's "Kizer x You" design competition. Its defining feature is a modular inlay system with four swappable handle panel options: rainbow Damascus, crystallized titanium, titanium Damascus, and textured zirconium.

What steel is used in the Kizer Quoll?

Every Quoll uses CPM-S45VN hardened to 60-61 HRC, with a flat-ground drop point. S45VN is a powder-metallurgy stainless with higher chromium than S35VN and a small nitrogen addition, giving it strong corrosion resistance and high edge retention.

Are the Quoll inlays really interchangeable?

Yes. The inlay panels are designed to be swapped, and Kizer markets the system around collecting, trading, and customizing. All four factory versions share the same titanium frame, so panels are interchangeable across the lineup.

How do you open the Kizer Quoll?

The Quoll opens with a titanium thumb disk as the primary opener and a front flipper tab as the secondary option. The blade rides on caged ceramic ball bearings.

Which Kizer Quoll should I buy?

The crystallized titanium version ($169.95) is the best value and the natural entry point. The rainbow Damascus version ($199.95) is the most visually striking, the zirconium version ($219.95) is the stealthy DLC option, and the titanium Damascus version ($299.95) is the collector's pick.
