Review ULTRASHARP Ultra Sharp Double Sided Diamond Sharpening Stone 300/1200 Grit

The **Ultrasharp 850007323448 Ultra Sharp Double Diamond Sharpening Stone (300/1200 Grit)** is a premium, high-performance sharpening tool designed to restore razor-like edges to knives, scissors, and other cutting instruments with unmatched precision and efficiency. Engineered with a dual-sided diamond abrasive system, this stone combines two distinct grit levels 300 grit for coarse honing and 1200 grit for fine polishing into a single, compact yet durable package, making it ideal for both beginners and seasoned craftsmen seeking a versatile sharpening solution. The diamond-infused abrasive surface ensures rapid material removal and consistent edge restoration, eliminating the need for frequent resurfacing or replacement compared to traditional whetstones. Unlike conventional sharpening tools that rely on water or oil, this diamond stone operates dry, reducing mess and simplifying the sharpening process while maintaining exceptional durability. Its robust, ergonomic design features a flat, stable base that allows for controlled, even pressure application, minimizing the risk of uneven sharpening or accidental slips. Perfect for both kitchen knives, hunting blades, and precision tools, the Ultrasharp 850007323448 delivers professional-grade results with minimal effort, making it a staple in any serious sharpener s collection. Whether used to revive a dull chef s knife, restore the cutting performance of a pair of scissors, or refine the edge of a specialized tool, this stone s dual-grit construction ensures a seamless transition from coarse honing to ultra-fine polishing, leaving blades sharper and more precise than ever. Built to last, its diamond coating resists wear and maintains its effectiveness over countless sharpening sessions, offering exceptional value for its compact yet powerful design.

The **Ultrasharp 850007323448 Ultra Sharp Double Diamond Sharpening Stone (300/1200 grit)** is a popular choice for honing and sharpening knives, but like any tool, it has advantages and drawbacks depending on your needs, skill level, and budget.

### **Pros**

1. **Dual-Grit Design** The stone combines two grits (300 and 1200) in one, allowing for both rough honing and fine sharpening in a single pass. This is convenient for users who want versatility without needing multiple stones.

2. **Diamond Coating** The diamond abrasive is highly durable and effective at cutting through hardened steel, making it faster than traditional ceramic or aluminum oxide stones. It s particularly useful for knives with heavy wear or stubborn edges.

3. **Durability** Diamond stones last significantly longer than natural or synthetic stones, especially for heavy users or those sharpening frequently. The abrasive layer resists wear and maintains its cutting efficiency over time.

4. **Precision and Consistency** The controlled grit progression (from coarse to fine) helps achieve a sharper, more consistent edge with less manual effort compared to freehand sharpening on a whetstone.

5. **Ease of Use** Unlike some traditional stones that require soaking or frequent flattening, diamond stones often maintain their shape better, reducing the need for maintenance. They also work well with oil or water (though oil is generally preferred for diamond stones).

6. **Good for Beginners** The dual-grit system simplifies the sharpening process, making it accessible for those new to knife maintenance who may not yet understand the nuances of different grits.

7. **Works on Stubborn Edges** The coarse side (300 grit) can restore edges that have become dull or damaged, while the fine side (1200 grit) polishes the blade to a near-mirror finish.

8. **Compatibility with Most Knives** Suitable for kitchen knives, pocket knives, hunting blades, and even some tools, though extremely hard materials (like some high-end steel) may require additional steps.

### **Cons**

1. **Cost** Diamond stones are more expensive upfront than basic whetstones or ceramic rods. While they last longer, the initial investment may be a deterrent for casual users.

2. **Maintenance of the Stone** Unlike natural stones that can be reshaped or flattened, diamond stones cannot be "repaired" in the same way. Once the diamond coating wears down unevenly, the stone may no longer cut effectively, requiring replacement.

3. **Limited Grit Range** The fixed 300/1200 grits may not be ideal for all sharpening tasks. For example:

- A very dull or damaged blade might need a lower grit (e.g., 100 300) to rebuild the edge properly.

- Some users prefer a finer final grit (e.g., 2000 6000) for a razor-sharp edge, which this stone does not provide.

- For Japanese knives (e.g., Gyuto or Santoku), a finer progression (e.g., 1000/6000) is often recommended.

4. **Requires Proper Technique** While easier than freehand sharpening, diamond stones still demand correct angle control (typically 15 20 degrees for Western knives, 8 12 degrees for Japanese) and even pressure to avoid burning the blade or creating uneven edges.

5. **Oil Dependency** Diamond stones perform best with oil (e.g., mineral oil or sharpening oil), which helps lubricate and flush away debris. Water can clog the diamond coating over time, reducing effectiveness.

6. **Not Ideal for Very Hard Steels** Some high-end or stainless steels (e.g., certain Damascus or powder metallurgy steels) may require additional steps (like pre-honing or using a finer stone) to achieve optimal sharpness.

7. **Size and Portability** The stone is relatively large (likely around 6x3 inches), which may not be as portable as a pocket-sized ceramic rod or a small whetstone.

8. **Potential for Over-Sharpening** If used incorrectly (e.g., too much pressure or wrong angle), the stone can remove too much material quickly, especially on the coarse side, leading to unnecessary blade thinning.

---

### **Comparison to Alternatives**

- **Single-Grit Diamond Stone**: More versatile if you need a specific grit progression (e.g., 1000/6000 for Japanese knives).

- **Whetstones (e.g., Arkansas, Japanese)**: Cheaper, more customizable grits, and can be reshaped, but require more maintenance.

- **Ceramic Rods**: Portable and good for touch-ups, but not as effective for restoring heavily dulled edges.

- **Electric Sharpeners**: Faster and easier for beginners, but less precise and can damage blades if misused.

---

### **Conclusion and Recommendation**

The **Ultrasharp 850007323448 (300/1200 grit)** is an excellent choice if you:

- Want a **versatile, durable, and efficient** sharpening tool without needing multiple stones.

- Prioritize **speed and ease of use**, especially for Western-style knives (e.g., chef s, hunting, or utility knives).

- Are willing to invest in a **long-term solution** that reduces the need for frequent replacements.

- Don t require ultra-fine edges (e.g., for slicing fish or paper) and are okay with a slightly less polished finish than a 6000-grit stone.

**However**, if you:

- Sharpen **Japanese knives** (e.g., Gyuto, Pakka, or high-carbon steels) regularly, consider a **1000/6000 grit diamond stone** or a high-quality whetstone (e.g., Naniwa or Shun) for better results.

- Work with **very hard or exotic steels**, you may need additional steps (e.g., pre-honing with a rod or using a finer stone).

- Prefer **lower-cost options** or **portability**, a whetstone or ceramic rod might be more suitable.

- Are a **beginner** and unsure about angles or technique, you might benefit from starting with a **single-grit diamond stone (e.g., 1000 grit)** or a guided electric sharpener before moving to a dual-grit system.

**Final Recommendation:**

For most **Western knife users** (e.g., kitchen knives, hunting blades) who want a **reliable, no-frills sharpening tool**, the **Ultrasharp 300/1200 grit diamond stone is a strong choice**. It strikes a good balance between convenience, durability, and effectiveness. Pair it with **mineral oil** for best results, and practice maintaining a consistent angle (around 15 20 degrees for most knives).

If you re sharpening **Japanese knives** or need **ultra-fine edges**, supplement this stone with a **higher-grit stone (e.g., 2000 6000)** or a dedicated Japanese whetstone. For casual users or those on a budget, a **single-grit diamond stone or a basic whetstone** may suffice.
