RH Preyda Flattening Stone 120grit Review

Everything You Need to Know About the RH Preyda Flattening Stone 120grit

For anyone who works with sharpening stones, maintaining the flatness of your sharpening surfaces is absolutely crucial for achieving consistent and effective edge refinement. The RH Preyda Flattening Stone 120grit presents itself as a no-nonsense tool designed for this specific purpose. It’s a direct-access solution, meaning it tackles the problem head-on without any complex mechanisms.

My own journey to acquiring this flattening stone stemmed from a growing frustration. My premium sharpening stones, which I’d invested a considerable amount of money in, were developing noticeable dished-out areas from regular use. This unevenness was not only making it difficult to sharpen my tools to their full potential but was also a constant reminder of my own tools’ declining performance. I needed a robust and reliable way to quickly restore their flat surfaces, and fast.

Upon first inspection, this flattening stone exhibits a utilitarian, no-frills design. The 120 grit abrasive surface feels substantial, and the overall heft suggests it’s built to withstand some serious abrasion. It’s reassuringly solid, not flimsy or overly delicate, hinting at its intended purpose of aggressive material removal. While I considered some larger, more elaborate diamond plates, their significantly higher price point pushed me towards a more traditional, stone-based solution for this particular task. The immediate impression was one of relief; a tangible tool ready to address a persistent problem.

Real-World Testing: Putting RH Preyda Flattening Stone 120grit to the Test

First Use Experience

My initial testing took place on my dedicated sharpening bench in my workshop. I placed the RH Preyda Flattening Stone 120grit on a damp cloth to provide some stability, as it doesn’t have a dedicated base on its own. I immediately began working on a water stone that had a significant concave dip in its center.

The performance in this workshop environment was exactly as expected for a 120 grit stone. It was aggressive, quickly removing material from the dished areas of the water stone. The process required moderate pressure and consistent circular motions to ensure even flattening. It was remarkably intuitive; no complex instructions or setup were needed, just a bit of elbow grease.

After that first extended session, the most noticeable outcome was the significant reduction in the stone’s dishing. There were no unexpected quirks, but the sheer amount of fine grit dust produced underscored its abrasive nature.

Extended Use & Reliability

Over several weeks of consistent use, this flattening stone has proven to be a reliable workhorse. I’ve used it to flatten my primary water stones, a couple of oil stones, and even a diamond sharpening plate that had developed minor inconsistencies. It has held up admirably, showing only minor signs of wear on its abrasive surface.

Durability is a strong point for this Arkansas stone. Despite being subjected to vigorous scrubbing and the removal of abrasive particles, there are no visible cracks or significant degradation in its performance. Maintenance is straightforward; a good rinse under running water and allowing it to air dry is usually sufficient. I make sure to clean out any slurry that accumulates on its surface after each use to prevent it from clogging.

Compared to my previous experiences with coarser grit sandpaper and a flat block, this dedicated flattening stone is far superior. It provides a more consistent and efficient abrasive action without the risk of tearing or uneven wear that can happen with improvised methods. It’s certainly a step up from budget alternatives that might use less robust abrasive materials.

Breaking Down the Features of RH Preyda Flattening Stone 120grit

Specifications

The RH Preyda Flattening Stone 120grit is a rectangular block measuring approximately 8″ x 3″ x 0.75″. It’s crafted from an Arkansas stone, known for its fine-grained abrasive properties. The stated grit is 120 Grit, which positions it as a relatively coarse abrasive, ideal for aggressive material removal. It also features a non-slip base, a practical addition for stability during use. The product comes boxed with hanging tab, indicating it’s ready for retail display and easy storage.

The dimensions are generous enough to comfortably flatten most standard sharpening stones without excessive effort or requiring an overly large workspace. The 120 grit is specifically chosen for its ability to quickly restore flatness, acting as a primary flattening tool. The non-slip base is a critical feature, preventing the stone from shifting or sliding during the abrasive process, which enhances safety and efficiency.

Performance & Functionality

The primary job of this flattening stone is to restore flatness to other sharpening stones, and it performs this task exceptionally well. Its 120 grit surface aggressively cuts away high spots and dishing, restoring a true plane to worn stones. It excels at quickly removing moderate to severe dishing, making the subsequent sharpening process much more effective.

One of its significant strengths is its straightforward functionality; it does exactly what it’s supposed to without any fuss. A potential area for improvement, though minor, could be even finer grit options for those who want to polish the flattening stone itself after heavy use, but for its intended coarse role, it’s excellent. It clearly meets and exceeds expectations for a tool at this price point for its core function.

Design & Ergonomics

The build quality of this RH Preyda Flattening Stone 120grit is quite good, especially considering it’s an Arkansas stone. The material feels dense and hard, suggesting good wear resistance. The non-slip base is a thoughtful touch, providing a secure grip on most work surfaces.

Ergonomically, the 8″ x 3″ dimensions make it comfortable to hold and maneuver. The thickness of 0.75 inches provides ample material for longevity and a solid feel in the hand. The abrasive surface itself is consistent, with no obvious low or high spots that would interfere with the flattening process.

Durability & Maintenance

This flattening stone is designed for durability and should last a very long time with proper care. As an Arkansas stone, it’s inherently hard and resistant to chipping or cracking under normal workshop conditions. The main wear will be on the abrasive surface, which is expected as it performs its function.

Maintenance is straightforward; simply rinse it thoroughly with water after each use to remove swarf and abrasive slurry. Allowing it to air dry completely is important to prevent any potential issues. I haven’t noticed any significant failure points, though like any abrasive, repeated heavy use will eventually wear down the grit.

Accessories and Customization Options

The RH Preyda Flattening Stone 120grit comes essentially as a standalone unit. Its primary feature is the 120 Grit abrasive surface and the non-slip base. There are no other included accessories, and customization isn’t really applicable to a tool of this nature.

However, it’s worth noting that some users might choose to add a dedicated splash-and-go method for keeping it wet, perhaps a small spray bottle of water. Its compatibility with other systems is simply its ability to flatten other stones, making it a universal tool in that sense.

Pros and Cons of RH Preyda Flattening Stone 120grit
