Review DMT Inch Dia sharp Mdiamond Bench Stone Extra coarse Handheld Sharpener
The **DMT 744759100405 Dia-Sharp MDiamond Bench Stone Extra-Coarse Handheld Sharpener** is a premium, high-performance sharpening tool designed to restore razor-sharp edges to knives, axes, chisels, and other cutting tools with unmatched precision and efficiency. Engineered with DMT s proprietary **MDiamond technology**, this bench stone combines the durability of diamond grit with the versatility of a traditional whetstone, delivering an ultra-coarse (800-grit) abrasive surface that quickly removes dullness and resharpenes even the most stubborn blades. The **dia-sharp** designation indicates its diamond-infused composition, ensuring consistent, long-lasting performance without the need for frequent reconditioning or replacement. Unlike conventional stones that require frequent flattening or dressing, this bench stone maintains a flat, true surface throughout its lifespan, making it ideal for both professional craftsmen and serious home users who demand reliability and speed.
The **extra-coarse grit** (800-grit) is perfectly suited for restoring severely dulled or damaged edges, as well as for initial sharpening of new or neglected blades before transitioning to finer stones for a polished finish. Its **handheld design** allows for easy portability and use on workbenches, countertops, or even in the field, making it a versatile addition to any toolkit. The stone s **compact yet sturdy construction** ensures stability during use, reducing the risk of slippage while sharpening heavy-duty tools like hatchets or pruning shears. The **flat, non-slip base** provides a secure foundation, allowing users to apply consistent pressure and achieve uniform results across the blade s edge.
What truly sets this sharpening stone apart is its **low-maintenance operation**. Unlike traditional whetstones that require frequent flattening with a dressing stick or honing oil, the **MDiamond technology** self-regenerates, maintaining its sharpness and flatness with minimal upkeep. This not only extends the stone s usable life but also saves time and effort, making it a cost-effective investment for frequent sharpeners. The stone s **durable, water-resistant diamond coating** ensures longevity even with heavy use, while its **smooth, non-abrasive sides** allow for easy cleaning and storage.
Whether you're a woodworker refining your carving knives, a gardener restoring your pruning shears, or a survivalist maintaining your survival knife, the **DMT Dia-Sharp MDiamond Bench Stone (Extra-Coarse)** delivers professional-grade results with ease. Its **precision-engineered design**, combined with the efficiency of diamond abrasion, makes it an indispensable tool for anyone serious about achieving a razor-sharp edge quickly, consistently, and with minimal effort. Perfect for both beginners and experts, this bench stone bridges the gap between convenience and craftsmanship, ensuring that every sharpening session yields a flawlessly honed blade.
**Pros and Cons of buying a DMT 744759100405 (Dia-Sharp MDiamond Bench Stone Extra-Coarse Handheld Sharpener)**
### **Pros**
1. **Effective for Heavy-Duty Sharpening** The extra-coarse grit (typically around 300 400 grit) is ideal for restoring dull or damaged blades, including chisels, knives, and tools with significant wear. It quickly removes material, making it faster for rough sharpening compared to finer stones.
2. **Durable and Long-Lasting** Diamond-coated stones are known for their longevity, especially when used on hard materials like steel. The diamond particles embedded in the resin or metal base resist wear better than traditional ceramic or aluminum oxide stones, extending the tool s usable life.
3. **Versatility** While primarily designed for bench use, the handheld design (though not as precise as a fixed setup) allows for portability. It can be used on-site for quick touch-ups, though precision may be limited compared to a dedicated bench stone.
4. **Good for Stubborn Blades** The coarse grit excels at sharpening blades with deep nicks, uneven edges, or heavily worn tips, which finer stones might struggle to address efficiently.
5. **Low Maintenance** Unlike some water stones that require frequent soaking or honing, diamond stones generally need only occasional cleaning with a brush or water to remove debris.
6. **Cost-Effective for Heavy Use** For users who frequently sharpen tools or work with tough materials, the upfront cost is justified by its durability and performance over time.
---
### **Cons**
1. **Not Ideal for Fine Finishing** The extra-coarse grit is designed for aggressive sharpening, not for achieving a razor-sharp edge or mirror polish. Users will need to follow up with a finer stone (e.g., 1000 grit) for a perfect edge.
2. **Limited Precision Without a Bench Setup** While handheld, the stone lacks the stability of a fixed bench stone, which can lead to inconsistent angles or uneven sharpening if not held steady. A bench mount would improve accuracy.
3. **Potential for Over-Sharpening** The coarse grit can remove too much material if used improperly, especially on thin or delicate blades. This may require extra care or multiple passes with finer stones to restore the blade s integrity.
4. **Dust and Mess** Diamond stones generate more dust and debris than some alternative sharpening methods (e.g., whetstones or ceramic rods). This can be messy and may require more frequent cleaning of the workspace.
5. **Weight and Ergonomics** The handheld design may feel heavy or awkward for prolonged use, especially if the user has hand or wrist issues. A bench-mounted version would be more ergonomic for extended sessions.
6. **Limited to Steel and Hard Materials** While excellent for steel, diamond stones may not be as effective on softer metals (e.g., copper, aluminum) or non-metallic materials like glass or ceramics.
7. **Higher Initial Cost** Compared to basic ceramic or aluminum oxide stones, diamond stones are more expensive upfront. However, this is often offset by their longevity.
---
### **Conclusion**
The DMT Dia-Sharp MDiamond Bench Stone (extra-coarse) is a **highly effective tool for aggressive sharpening tasks**, particularly for users who need to restore dull or damaged blades quickly. Its diamond coating ensures durability and performance, making it a worthwhile investment for professionals, DIY enthusiasts, or anyone who frequently works with tools. However, it is **not a standalone solution** users will need to pair it with finer stones for achieving a polished edge. The handheld design offers convenience but sacrifices some precision compared to a bench-mounted setup.
If your primary need is **rough sharpening, tool maintenance, or restoring worn blades**, this stone is an excellent choice. If you require **fine-tuning or frequent use on delicate blades**, consider supplementing it with a finer stone or investing in a dedicated bench setup.
### **Recommendation**
**Buy it if:**- You frequently sharpen chisels, knives, or tools with significant wear.
- You prioritize durability and aggressive material removal.
- You re willing to use it as part of a multi-stage sharpening process (coarse fine grits).
**Avoid it if:**- You only need occasional, light sharpening (a basic ceramic or whetstone may suffice).
- You require ultra-precise, mirror-finish edges without additional tools.
- You dislike handling dust or prefer a more ergonomic, bench-mounted solution.
For the best results, pair this stone with a **finer diamond or ceramic stone (e.g., 1000 grit)** and use a **bench guide or jig** to maintain consistent angles. If budget allows, a bench-mounted version would further enhance accuracy.
