How We Tested of Multi-tool Knives

The interchangeable wire cutter jaws (as observed here on the Wave) on some of Leatherman’s higher-end models are a valuable feature addition to assist their tools in moving towards the realm of “buy-it-for-life.”

Examining multi-tools is just as simple as it sounds – We utilize them in everyday and task-specific labor. Our test team is chosen to include individuals who work and engage in activities with their hands in distant and challenging environments where the use of a multi-tool enhances its usefulness. In this “real-world” setting, we gain the most insight into a tool’s functionality and quality and become passionate critics or firm advocates of even the smallest design choices. However, this environment does not provide us with all the knowledge we require. We supplement the user testing with a few standardized tests that question and contribute to the insights we gather in the field.

Capabilities

Initially, we take inventory of the capabilities of the multi-tool through a simple tally. Manufacturers are notoriously generous in their count of functionalities, labeling barely different tool modifications as a complete achievement on the tool’s record. It is crucial to approach the marketing language with skepticism. Indeed, all four-function pliers may genuinely be useful, but at the end of the day, they are still just a single pair of pliers.

Next, we employ each capability in its intended usage. Through this, we determine the actual utility. An included tool should not truly “count” if it is not distinctly different or efficient. Lastly, we assign an importance rating to each capability to derive a final score. We have always believed that the ideal multi-tool should incorporate locking pliers, blades deployable with one hand, scissors, a can/bottle opener, a file, pocket clip carry (not a capability, but something we highly value), and a 1/4″ bit driver. When a tool encompasses one or more of these ideal capabilities (and none that we have discovered includes all of them), it elevates the score more than a mere “vanity” capability would.

The capabilities of a multi-tool are evaluated based on their number and usefulness. Having more is not necessarily better if some or all of them do not function effectively.

Building Quality

Building Quality is initially assessed with a fundamental first impression. Hinge force, lock movement, and shaking factor in each tool reveal a great deal about the overall building quality of a multi-tool, as does an inspection of the blade’s sharpness to ensure that there are no rough edges. We are yet to encounter a quality problem with a tool that surprised us. Additionally, we carry out tasks with the tools meant for extensive use. With every pair of pliers, we bend and cut a coat hanger of full thickness. With every blade, we engage in at least a few minutes of carving on hardwood. Lastly, we use every tool for months, just like you will. If anything, we purposely find reasons to use our tested multi-tools so that they will go through more than average usage before we draw any review conclusions.

Using a multi-tool as a hammer is clearly a “non-standard” use. However, real remote travel demands enduring gear abuse. High building quality makes a tool more resistant to abuse.

Ergonomics

The only real way to assess ergonomics is through use. We understand the factors that affect ergonomics, but none of it matters until we actually use the tools in their intended applications. We look for smooth edges, minimal to no interference between tools, and locks that function smoothly and reliably. Do the pliers cause discomfort in your palm after cutting 16-gauge fencing for an hour? Is the driver positioned centrally and securely locked to prevent slipping off the screw?

Ergonomics are easily evaluated if you truly use the tools as intended. For example, we didn’t notice the handle interference of blades accessed internally (as shown here) until we extensively used tools like this.

Portability

We measure each device for weight, length (when closed, with deployed pliers, with the main blade open, and the effective edge of the main blade), and thickness (excluding any pocket clip). Furthermore, we identify various ways to carry. Having a sheath included is convenient. Carrying with a pocket clip is highly regarded. Smaller tools that can be carried on a keychain are commended for their portability.

Portability depends on size and weight, as well as carry options. A sheath is usually the most practical, but the least socially acceptable method of carrying.

Conclusion

Our testing process is as comprehensive as possible. We apply years of experience and a truly professional-level perspective, and then convey our findings in a simple and clear manner. There are numerous resources available on the internet for more in-depth examinations of multi-tools. However, none of them compare products in the same way we do, with the same level of experience, and with the casual to enthusiastic user in mind like we do.
