Leatherman Arc Review: 4 Reasons to Buy It and 4 Reasons to Skip It

Introduction

After about four months of carrying the Leatherman Arc as a primary multi-tool, it is time to weigh up who should actually buy it. This tool sits at $230 in most places, which is serious money for a pocket tool, and the honest answer is that it is an easy recommendation for some buyers and a poor one for others. Here are four reasons to consider it and four reasons you may want to skip it.

Why People Are Drawn to the Leatherman Arc

The biggest reason behind the hype is the tool set itself. Beyond the blade, the four outer implements are exactly what people have been asking for: a saw, a diamond file with an aggressive cross-cut surface plus serrations for cutting soft metal, a larger pair of outside-accessible scissors, and a full straight blade with no partial serration. Combined with the bit driver and micro bit driver, this is a selection people have wanted for close to two decades and never really got in any other platform. The Free P4 missed the mark slightly and the Wave never quite nailed it; the Arc finally keeps the reamer and the large scissors at the same time.

The second reason is the platform itself. The Arc is currently the only available Free series plier-based multi-tool, with the P2 and P4 not being sold. It is a one-handed platform, so any inner or outer implement can be accessed regardless of which hand you use. Left-handed users can even swap the blade into the saw location using the removable thumb stud, with a pocket clip spot on that side, turning it into a genuinely left-handed tool.

The third reason is harder to spot: the Arc is currently the only Leatherman being made that technically qualifies as USA made. Other tools like the Wave Plus are assembled in the United States but do not meet the 70% domestic content threshold. The Arc does, which required moving components like the bit driver and plier head in-house at considerable cost.

The MagnaCut Blade

The headline feature is the MagnaCut blade, and it is better than initially expected. The factory grind is relatively even and the sharpening choil is present, better than many multi-tools arrive out of the box. It works well enough as a primary knife that a separate folding knife becomes unnecessary: it handled food prep, package opening, and general utility work over months of use.

The coating turned out to be a genuine bonus. MagnaCut already has strong corrosion resistance, so the coating seemed pointless at first, but it makes sticky substances like tape glue far less likely to adhere, which makes the blade easier to keep clean. Compared to steels like S30V or 154CM used in other tools, MagnaCut offers significantly better edge retention.

The Cutter Problem

The most serious negative is not unique to the Arc: it affects Leatherman tools made from 2021 onward that use replaceable cutters. The newer cutters have a large gap at the bottom of the jaws compared to the older design, which makes hard-wire cutting worse and produces incomplete cuts on materials like wire ties. Sliding a tie all the way down and closing the pliers can leave a substantial amount of material uncut, where the older cutters left only a small remnant.

There is also a heat treatment concern. A batch of Arc cutters was not properly hardened, and a coat hanger test was enough to break cutters on one unit. A newer unit with better heat-treated cutters survived the same test but still produced incomplete cuts, catching material instead of shearing it through.

The warranty situation makes this worse. Contrary to what was once assumed, replacement cutters from Leatherman are not the older, better design, and Leatherman will only send replacement cutters if yours are actually broken. The policy is entirely reactive rather than preventive.

Bit Kit and Accessory Gripes

The included bit kit is a strange combination of pieces from two different bit kits. It is missing one of its ten slots entirely, it does not include the Precision bit as a backup, and it omits the T6/T8 bit that is among the most useful for adjusting pocket clips and similar tasks. To get a complete set you effectively have to buy additional kits, which makes the included one feel like a box of spare parts.

There is also a secondary issue: using the rear end of the tool as a hammer can shake the small retention protector enough that the Leatherman bit or Precision bit can fall out and be lost. This is not a problem on the Free P4, which has no loose parts. An extender accessory would arguably have made more sense in the box, since it would allow use of quarter-inch Leatherman bits and Weha double-sided bits.

Where the Arc Falls Short for Knife Enthusiasts

MagnaCut spans a wide usable hardness range, roughly 58 to 65 HRC, but the Arc’s blade appears to be run considerably softer than ideal. Based on testing data, the best balance of toughness and edge retention sits around 62-63 HRC, with practical results often quoted between 58 and 61. Knife enthusiasts may find it underperforms other MagnaCut blades as a result.

The blade geometry is also very thick behind the edge. That hurts slicing performance and longevity when cutting abrasive materials, and MagnaCut excels with thin edges, so it feels like a missed opportunity. The limited 40th anniversary multi-tool had a nice thin full flat grind that would have been a better route. For utility tasks and food prep this is not a dealbreaker, but it is not the slickest blade around either.

Is the Price Justified?

At $230 pretty much everywhere, the Arc is expensive, and the grounding principle applies: if you are not carrying it on your person every single day, in a pocket or a holster, you are overpaying. You would be better served by an inexpensive multi-tool or a small proper toolkit for your bag with better individual tools.

That said, there is a way to justify the price. The 25-year warranty covers more than most companies would and could reasonably be valued at $40-50 of the total. The MagnaCut blade alone accounts for roughly $30-40 given raw material cost and the extra machining, heat treatment, and finishing time a vanadium steel requires. In-house production of the bit driver adds $5-10, and the bit kit and micro driver add another $5-10 in value, though not everything included is something every buyer wants to pay for.

Conclusion

The Leatherman Arc nails the tool selection people have wanted for years, offers a genuinely ambidextrous one-handed platform, is technically USA made, and carries an excellent MagnaCut blade that can replace a dedicated folding knife for everyday tasks. Against that: softer and thicker blade geometry than enthusiasts would like, a serious cutter design and heat treatment problem shared with post-2021 Leatherman tools, a nonsensical bit kit, and a $230 price that only makes sense for true daily carriers. If you will carry it every day, it is a strong buy. If not, look elsewhere.
