JerryRigEverything, the nom de guerre of Zach Nelson, has carved a significant niche in the tech review landscape through his rigorous and often destructive durability tests and insightful teardowns. His YouTube channel, boasting millions of subscribers, has become the go-to destination for consumers and enthusiasts seeking an unvarnished truth about how well their favorite gadgets hold up under duress. Nelson’s methodology is straightforward yet undeniably effective: subjects his devices to a barrage of tests designed to simulate real-world (and sometimes exaggerated) scenarios of wear and tear, followed by deconstructions that reveal the intricate engineering and potential vulnerabilities within.

How JerryRigEverything Uses the Mohs Scratch Test

At the heart of JerryRigEverything’s durability tests lies a meticulous examination of surface resilience, primarily through the application of the Mohs scale of mineral hardness. This standardized system, which ranks minerals from 1 (talc) to 10 (diamond) based on their ability to scratch one another, provides a quantifiable method for assessing how well a device’s screen and casing will resist everyday abrasions. Nelson employs a set of calibrated picks ranging from Mohs hardness level 2 to 9, systematically scratching the device’s surfaces.

Mohs Level 2 and 3: The First Line of Defense

The initial stages of Nelson’s scratch test involve using picks of Mohs hardness levels 2 and 3. These levels represent common culprits like sand and fingernails, offering an immediate insight into how a device will fare against minor everyday encounters. Devices that begin showing visible scratches at these lower thresholds are often flagged as being less durable, raising concerns for users who prioritize pristine aesthetics. For instance, while many modern smartphones boast impressive scratch resistance, even subtle marks at this level can be a predictor of future wear. The iPhone 17 Series, with its Ceramic Shield screen, has demonstrated its prowess by withstanding scratches at Mohs level 7, indicating a robust defense against common abrasions. This level of resilience suggests that everyday encounters with keys or coins are unlikely to mar its surface significantly.

Mohs Level 4 to 6: Identifying Deeper Scratches

As Nelson progresses to Mohs levels 4 through 6, he utilizes harder picks to simulate more aggressive interactions. Materials falling within this range can include harder minerals and even some common tools. The point at which a device begins to scratch at these levels offers a clearer picture of its structural integrity when faced with more significant forces. The Google Pixel 10 Pro Fold, unfortunately, displayed a concerning susceptibility, with its outer display, protected by Gorilla Glass Victus 2, beginning to show scratches at Mohs level 6. This finding is particularly noteworthy, as Gorilla Glass Victus 2 is marketed for its enhanced durability. The observation suggests that even premium materials can have specific vulnerabilities.

Mohs Level 7 to 9: The Ultimate Scratch Test

The highest levels of the Mohs scale, specifically 7 through 9, serve as the ultimate gauntlet for modern device manufacturing. While consumer electronics rarely encounter materials this hard in typical daily usage, testing at these levels provides essential data regarding the true limits of advanced materials like sapphire crystal, specialized glass composites, and high-grade ceramic coatings.

When a device resists scratching at Mohs level 7, it effectively demonstrates near-total immunity to common household hazards like metal keys, copper coins, and standard pocket debris. However, as Nelson advances to level 8 and 9, the intent shifts from testing “durability” to investigating “composition.” If a screen surface or protective cover sustains damage at level 8, it indicates that the manufacturer has likely opted for a glass-based hybrid rather than pure synthetic sapphire.

By pushing materials to these extreme thresholds, JerryRigEverything reveals the distinction between marketing claims and chemical reality. For enthusiasts and prospective buyers, this information is invaluable; it separates devices built to withstand the rigors of long-term ownership from those that may appear premium on the surface but falter when subjected to the harsh, unforgiving physics of the Mohs hardness test.
