Leatherman Skeletool CX Review: The Multi-Tool That Knows When to Stop

Most multi-tools are sold by addition: one more driver, one more saw, one more reason to make the handles thicker. The Leatherman Skeletool CX is sold by subtraction. It keeps the tools people reach for most—pliers, a knife and a driver—then stops at five ounces. That restraint is why owners carry it, and it is also the reason not to buy it if you expect a pocket toolbox.

We verify manufacturing against primary sources, read what actual owners report, and never accept payment for rankings.

The design works because it makes a hard promise and keeps it. The plain-edge 154CM blade opens from the outside. The pliers are full-length but narrow. Leatherman’s flat-bit driver carries one bit and stores a second in the handle. The carabiner doubles as a bottle opener, and the removable pocket clip gives the tool two ways to travel without adding a sheath.

It is not a Wave Plus on a diet. The Skeletool CX omits scissors, a file, a saw, a can opener and every small specialty implement that makes a full-size multi-tool useful at a workbench. That is not an oversight. It is the whole proposition: carry seven functions every day instead of eighteen functions occasionally.

Which Skeletool CX is this, exactly?

This review covers the current Skeletool CX in Onyx, Leatherman SKU 833131, and the exact retail route selected by the Buy American Store, ASIN B000059GTH. It is the seven-tool model with a black 154CM straight-edge blade, black PVD-coated frame and a removable pocket clip. It is not the standard Skeletool, whose blade is a combination straight/serrated edge, and it is not the red Skeletool RX, which is built around emergency-response use.

The retail listing is messier than the tool. Its headline correctly identifies the Skeletool CX and Onyx color, but a secondary line still calls the blade a “combo knife.” Leatherman’s current Onyx specifications, current product description, comparison table and the listing’s own current feature bullets all identify a straight-edge 154CM blade. The same retail family also pools reviews across several colors and older configurations. Buy by the model, Onyx selection and SKU above—not by every stray phrase in the family listing.

What it’s like to carry

Five ounces is the specification that matters. A full-size multi-tool can be excellent and still spend its life in a drawer because it drags at a pocket. The Skeletool CX is closer to a substantial folding knife with useful pliers attached. The open frame removes visual and physical bulk, the clip holds securely without making the draw a struggle, and the carabiner can hook to a pack loop when pocket carry is inconvenient.

The outside-accessible knife is the reason it can replace a pocket knife rather than merely accompany one. A thumb hole opens the 2.6-inch blade one-handed, and a liner lock holds it open. The 154CM steel is the defining CX upgrade over the standard Skeletool: it holds an edge better than 420HC while remaining reasonably corrosion resistant and serviceable. Owners repeatedly praise the factory edge and report using the blade far more often than the pliers.

The pliers are capable within the frame’s design limit. They handle small fasteners, bent pins, fishing hardware, hobby work, cable ties and the other awkward jobs that make bare fingers inadequate. They are not a substitute for full-size linesman’s pliers, and the narrow handles concentrate pressure when you squeeze hard. Treating them as light- to medium-duty pliers is not babying the tool; it is using the geometry honestly.

The bit driver is more useful than its size suggests. The tool ships with a Phillips #1/#2 bit and a 1/4-inch/3/16-inch flat bit, one in the driver and one retained in the handle. Leatherman’s flat bits save space, but they are thinner than standard quarter-inch bits and are better for ordinary screws than high-torque work. An extender and bit kit broaden the system, although doing that starts to defeat the reason for choosing the Skeletool in the first place.

What owners actually say

The exact retail route shows 4.7 out of 5 from 3,333 ratings. Eighty-three percent are five-star ratings, and the recurring praise is unusually consistent: owners call it light enough to disappear in a pocket, complete enough for daily tasks and more useful than heavier tools they stopped carrying. Long-term reports commonly describe years of near-daily use with the blade, pliers and driver covering the jobs that actually occur.

The complaints are equally useful. Durability is the main mixed category in the owner record. Most owners describe sturdy pliers; a minority report broken plier jaws, including a recent verified-buyer report on Leatherman’s own site of a jaw failing after two weeks without unusual stress. That is not the dominant experience, but it is a real failure mode and one the warranty should address.

Ease of use is also mixed. Several owners say the pivots and blade arrive stiff and loosen after regular use. A current Onyx owner specifically notes the break-in period, wishes the tool had scissors and cautions that the flat bits are for modest torque. Another recent owner says the bit holder began to feel less secure with repeated use, although the bit had not fallen out. Those are credible limitations because they follow directly from the compact design rather than contradicting it.

The most important review-reading caveat is aggregation. The retail page combines colors and multiple years of Skeletool CX inventory, so some highly ranked reviews refer to stainless versions, included sheaths or older carbon-fiber trim. We used the owner record for recurring performance themes, then checked the current Onyx configuration against Leatherman’s own specifications. That is why this review says straight-edge blade, sheath sold separately and SKU 833131 even when an old review or stale subtitle says otherwise.

Pros & Cons

Pros: At five ounces it is light enough for real daily carry; the outside-accessible 154CM straight-edge blade is a meaningful upgrade over the standard Skeletool; the pliers and bit driver cover the most common unplanned jobs without full-size bulk; the pocket clip and carabiner give flexible carry options; the second bit stores in the handle; the owner record is both large and strongly positive; it is manufactured in Leatherman’s Portland factory; and the 25-year warranty gives a clear remedy for the minority of tools that develop a genuine defect.

Cons: There are no scissors, saw, file or can opener; the narrow handles are less comfortable under hard plier pressure; the flat bits are compact but not designed for high torque; the pivots can need a break-in period; durability feedback is mixed at the margins, with isolated plier-jaw failures; the sheath is sold separately; Leatherman’s origin statement is qualified rather than fully domestic; and the retail family mixes colors, years and stale copy, so buyers need to confirm Onyx and the exact model instead of trusting every subtitle.
