Review DMT Inch Dia sharp Bench Stone Extra coarse Handheld Sharpener
The **DMT 313044875849 Dia-Sharp Bench Stone Extra-Coarse Handheld Sharpener** is a premium, high-performance sharpening tool designed to restore razor-sharp edges to knives, chisels, scissors, and other cutting instruments with precision and efficiency. Engineered for both professionals and serious hobbyists, this handheld diamond-coated bench stone combines durability with exceptional abrasive grit to deliver a consistently fine, honed edge in minimal time. The extra-coarse (800-grit) diamond abrasive surface is meticulously engineered to remove material quickly while maintaining control, making it ideal for resharpening dull blades that have seen heavy use or sustained damage. Unlike traditional whetstones that require frequent dressing or soaking, the diamond coating on this stone remains self-sharpening, ensuring a consistently smooth and even sharpening surface with every use. Its compact yet sturdy design allows for easy portability, making it perfect for both workshop and field applications, whether you're a carpenter refining chisels, a chef restoring kitchen knives, or a DIY enthusiast tackling precision tools. The ergonomic grip and balanced weight reduce hand fatigue during extended sharpening sessions, while the diamond-infused surface resists clogging and maintains its sharpness far longer than conventional stones. Whether you're working with high-carbon steel, stainless steel, or other tough materials, this bench stone delivers professional-grade results with minimal effort, making it an indispensable addition to any toolkit for those who demand perfection in their cuts.
**Pros and Cons of buying a DMT 313044875849 Dia-Sharp Bench Stone (Extra-Coarse, Handheld Sharpener)**
### **Pros**
1. **Effective for Stubborn Blades** The extra-coarse grit (typically around 220-300) is ideal for restoring severely dulled or damaged blades, including chisels, knives, and tools that have been neglected or used on abrasive surfaces. It removes material quickly, making it suitable for re-sharpening heavily worn edges.
2. **Versatile Use** The bench stone design allows for both handheld and fixed use, accommodating different sharpening techniques. It can be clamped to a bench for stability or held manually for precision work, depending on the task.
3. **Durable Construction** DMT is known for producing high-quality sharpening tools with durable materials. This stone is likely built to last, even with frequent use, though the exact composition (e.g., aluminum oxide or silicon carbide) would determine its longevity.
4. **Handheld Convenience** Unlike fixed bench stones, the handheld design offers portability, allowing users to sharpen tools on-site without needing a dedicated workspace. This is particularly useful for contractors, woodworkers, or DIY enthusiasts who move between locations.
5. **Cost-Effective for Heavy-Duty Work** For users who frequently sharpen very dull tools, the extra-coarse grit can save time and money compared to using finer stones repeatedly. It reduces the need for multiple sharpening sessions to achieve a usable edge.
6. **Complementary to Other Stones** This stone can serve as a pre-sharpening tool before moving to finer grits (e.g., 1000 ), making it a practical addition to a sharpening setup for achieving a polished edge.

### **Cons**
1. **Aggressive Grit Can Be Overkill** The extra-coarse grit is not ideal for maintaining already sharp blades or for fine finishing work. It may remove too much material too quickly, leading to unnecessary wear on well-honed tools. Users with delicate or thin blades (e.g., some pocket knives or Japanese knives) may find it too harsh.
2. **Requires Skill to Use Effectively** Achieving a consistent, sharp edge with a coarse stone demands practice. Poor technique can result in uneven sharpening, chipping, or even damaging the blade. Beginners may struggle to use it without guidance.
3. **Dust and Cleaning** Coarse stones generate a significant amount of abrasive dust, which can be messy and require frequent cleaning to maintain performance. The dust can also be abrasive to skin or eyes, necessitating proper ventilation or protective gear.
4. **Limited for Fine Work** While effective for restoring dullness, this stone is not suitable for achieving a mirror-like finish or honing a blade to razor sharpness. Users will need finer grit stones (e.g., 1000-8000) afterward for optimal results.
5. **Potential for Uneven Wear** If not used correctly, the stone s surface may wear unevenly, leading to inconsistent sharpening results. Proper flattening and maintenance are required to keep it effective over time.
6. **Not Ideal for All Blade Types** Some materials, such as high-carbon steel or certain alloys, may react poorly to aggressive sharpening, leading to accelerated rusting or weakening of the blade. Users should research compatibility with their specific tools.

### **Conclusion**
The DMT 313044875849 Dia-Sharp Bench Stone (extra-coarse) is a powerful tool for users who need to revive severely dulled blades quickly and efficiently. It excels in scenarios where time and material removal are priorities, such as restoring chisels, pruning shears, or neglected tools. However, its aggressive grit makes it less suitable for maintaining sharpness on well-honed blades or for fine finishing work. It is best suited for intermediate to advanced users who understand proper sharpening techniques or for those with a dedicated sharpening setup that includes finer grit stones for post-processing.
---
### **Recommendation**
**Buy this stone if:**- You frequently sharpen very dull or damaged tools and need a fast, effective way to restore their edges.
- You work with chisels, pruning shears, or other tools that require aggressive material removal.
- You already own finer grit stones (e.g., 1000 grit) to use after pre-sharpening with this stone.
- You value portability and versatility in your sharpening setup.
**Avoid this stone if:**- You primarily maintain already sharp blades and prefer finer grits for precision work.
- You are a beginner who may struggle with the technique required for optimal results.
- You work with delicate or thin blades that could be damaged by aggressive sharpening.
- You do not have a plan for cleaning or maintaining the stone properly.
**Final Verdict:** This is a valuable addition to a workshop for users who prioritize heavy-duty sharpening but should be paired with finer stones for comprehensive edge refinement. For casual users or those who mostly maintain sharpness, a finer bench stone or a honing rod may be more practical.
