Design and Build Quality
The Signal boasts a rugged design with stainless steel construction that has proven resilient against the elements.

Positive: The tool's durability is impressive. It has withstood numerous adventures, showing minimal wear and tear even after years of use. The robust construction ensures that it remains reliable in various situations.

Negative: However, the tool’s bulkiness at 7.5 ounces makes it less ideal for ultralight backpackers or those looking for a more pocket-friendly option. This weight can be cumbersome, particularly for those who prefer to travel light.

Tools and Features
The Signal comes equipped with 19 tools, including pliers, wire cutters, a saw, a hammer, a can opener, and various screwdrivers. Unique to its design are the ferrocerium rod, diamond-coated sharpener, and safety whistle, tailored for survival scenarios.

Positive: The survival tools are standout features. The ferrocerium rod and whistle are invaluable in emergency situations, and the sharpener is handy for maintaining the knife blade on the go. The pliers and wire cutters continue to perform exceptionally well, handling various tasks with ease.

Negative: Over time, certain tools have shown to be less intuitive and user-friendly. The can opener, for instance, lacks the efficiency found in dedicated can openers on other multitools. Additionally, the placement of some tools can be awkward, making use difficult in critical moments.

Hammer Use and Ergonomics
Positive: The hammer, though small, works well for its intended purpose. I haven't used it extensively over the years, but it has come in clutch when needing to tap something into place. Its design lends itself to being used heavily, although I personally haven't pushed it to its limits. The lock that keeps the arms from moving while hammering is a nice touch.

Negative: The handle design and tool usability present significant issues. When any of the internal tools are used, the handle needs to be extended. Due to the hammer end design, it’s impossible to use the implements in line with the tool body. Using internal tools with the handles open feels unnatural compared to previous Leatherman multitools. The can opener, while slightly more effective with separated handles, mainly works better because it allows closer access to the can lip. Screwdrivers work best when in line with the tool body, but the Signal’s design doesn’t allow for this, requiring the tool to be opened into an L shape or fully extended. These are compromises rather than purposeful design elements.

Handle Design: The curved handle can only be used in one orientation, similar to the Skeletool. Using it in an unintended way feels awkward and uncomfortable, another carryover from the Skeletool design that didn’t translate well to the Signal. The handle splay is worse than other tools of similar size in Leatherman’s lineup. With average-sized hands, gripping the Signal is challenging, and the handles spread further apart when clamping down on an object, making it tricky to maintain a good grip. This could be significantly improved with a redesign to reduce handle splay.

Longevity and Maintenance
Over the years, the Signal has shown admirable longevity. Regular maintenance, such as cleaning and lubricating moving parts, has kept it in good working condition.

Positive: The ease of maintenance is a strong point. Most components are straightforward to clean, ensuring the tool’s longevity with proper care. My current Signal, which is my second one, has yet to show signs of wear. I look forward to the many "battle scars" it will accumulate over time.

Negative: However, the design and placement of some tools still present challenges that can detract from its overall functionality.

Conclusion
Reflecting on nearly a decade of use, the Leatherman Signal remains a solid multitool choice for those who prioritize survival features alongside traditional multitool functionality. Its durability and diverse toolset make it a reliable companion for outdoor adventures and emergency preparedness.

However, the Signal’s design flaws, such as bulkiness, awkward tool placement, and handle design issues, have become more apparent over time. These issues have detracted from the overall enjoyment and usability of the tool. Despite these drawbacks, the Signal’s strengths in durability, versatility, and ease of maintenance make it a valuable addition to any outdoor enthusiast’s kit.

In summary, the Leatherman Signal has stood the test of time, offering a blend of reliability and innovation, albeit with some areas for improvement. For those willing to overlook its minor flaws, it remains a dependable multitool capable of handling a variety of tasks in diverse environments. However, a redesign addressing these issues would make it an even more compelling option.
