Overview of the SHARPAL 162N Double-sided Diamond Sharpening Stone
We were genuinely impressed by the thoughtful design and sturdy build of this sharpening stone.Featuring dual grit levels-a coarse 325 grit for fast edge setting and an extra fine 1200 grit for honing-it handles a wide variety of blades with ease, including high-speed steel, carbide, ceramic, and cubic boron nitride. One of the standout features is the exclusive MirrorFlat technology, which ensures the surface stays ultra-flat over time, unlike conventional oil or water stones that wear unevenly.Another design highlight is the integrated angle guide offering four global settings (14°, 17°, 20°, 25°), making it easier for us to maintain consistent sharpening angles. The included storage case doubles as a non-slip base, providing solid grip and added convenience during sharpening sessions.
When it comes to performance and usability,this tool delivers speedy and effective sharpening without the need for messy oils or water-simply sharpen dry! The industrial monocrystalline diamonds electroplated onto a thick stainless steel base accelerate the sharpening process,up to five times faster than conventional stones. This means less time spent and more precision achieved. For best results, we recommend starting with the coarse grit to re-establish the edge and finishing with the fine grit to polish and hone razor-sharp. Remember to use light, consistent strokes while keeping the blade aligned with the angle guide for optimal sharpening.

Several reviewers also appreciate that this diamond stone works well on a variety of steels - including tough tool steels and tungsten carbide blades – without any loss of sharpening speed or consistency.
Ease of Use & Design Features
There is a clear consensus that the SHARPAL 162N is very user-friendly,especially compared to traditional water stones:
- Dry sharpening: Users love that no water or oil is needed,meaning no mess and less prep time.
- Non-slip storage case/base: The sturdy case doubles as a stable sharpening platform with a rubber foam bottom,preventing any slip during use.
- Angle guide: While some find the included angle guide helpful for setting the initial bevel angle, most suggest relying on muscle memory for quicker and more consistent sharpening once confident.

One user shared a useful tip: placing the Sharpal leather strop on the case for neat, compact storage, showing that the system integrates well with complementary sharpening tools.
Longevity and Build Quality
The diamond stones come mounted on a nickel-plated steel backing, which customers feel is robust and durable.Several reviews mention the stone feels heavy and of high quality, with monocrystalline diamond coating that remains effective over time.
“the diamond grit seems to be quite durable after months of use.”
Most users indicate satisfaction with the 3-year warranty and express confidence that the stone will last well beyond this period.
Common Considerations
While the feedback is largely positive, a few minor points were noted:
| Consideration | Explanation |
|---|---|
| Initial Skill Required | Sharpening well still requires practice; some users experienced scratches when first using the stone but improved with technique. |
| Angle Guide Usage | Helps beginners set an angle but not recommended for continuous use as it slows down the process. |
| Steel Base Corrosion | A few noticed some minor corrosion on the steel backing if handled frequently and not stored perfectly dry. |
| Not Ideal for Ceramics | the coarsest 1200 grit side is too rough for ceramic knives; requires specialty stones/strops. |
Summary
From the breadth of detailed customer feedback, it’s clear the SHARPAL 162N delivers excellent value and performance for sharpening enthusiasts and casual users alike. It combines the speed and precision of diamond sharpening with practical design elements like a non-slip base and storage case.
