DMT Duo Sharp Plus Review

What Makes the DMT Duo Sharp Plus Stand Out?

As an equipment specialist with over a decade of experience across diverse environments, I’ve come to appreciate tools that offer robust performance and longevity. The DMT Duo Sharp Plus knife sharpener from DMT has certainly earned its place on my workbench, particularly for its dual-sided diamond abrasive and thoughtful design. This unit is designed for dedicated enthusiasts who demand reliable edge maintenance.

My search for a superior sharpening solution began when my existing multi-stage sharpener started exhibiting uneven wear and inconsistent results, particularly on smaller, more intricate blades. I needed something that could handle a variety of edge types without the fuss of oil or stones, something I could trust for quick touch-ups or more substantial re-profiling. The promise of diamond abrasives offered a compelling alternative to traditional methods.

Initial impressions of this diamond bench stone were very positive; the diamond plate felt substantial and the overall construction exuded a sense of quality. The included base also felt robust, providing a stable platform for sharpening. It immediately felt like a significant upgrade from less refined sharpening systems I’d encountered.

I briefly considered some ultrasonic sharpening systems and ceramic rod setups, but the inherent durability and versatility of diamond abrasives for a wide range of steels kept drawing me back to systems like this. The established reputation of DMT also played a significant role in my decision-making process.

My first reaction upon unboxing and initial inspection was one of quiet confidence; it felt like a tool designed to last and perform consistently. This initial assessment set a high bar for its subsequent real-world performance.

Real-World Testing: Putting **DMT Duo Sharp Plus** to the Test

First Use Experience

I primarily tested this bench stone in my home workshop, where I maintain a diverse collection of knives ranging from kitchen cutlery and woodworking tools to utility blades and pocket knives. My typical sharpening routine involves assessing the blade’s existing edge and then selecting the appropriate grit. The DMT Duo Sharp Plus was mounted securely onto its base on my workbench, providing a stable and comfortable sharpening station.

During these initial sessions, I intentionally exposed the sharpener to light dust from woodworking and the occasional minor water splash, common occurrences in a workshop environment. The diamond surface proved remarkably resistant to clogging, and any dust accumulation was easily brushed away. The continuous zone feature was immediately apparent, allowing for effortless sharpening of smaller pointed tools like awls and carving gouges without snagging.

The ease of use was exceptional. Unlike oil stones that require soaking or ceramic rods that can be finicky with angle consistency, diamond plates offer a consistent, aggressive bite from the start. I found myself able to achieve a sharp edge on a paring knife in under two minutes, a task that previously took significantly longer with my old setup. There were no surprising issues or quirks; it simply performed as advertised, delivering a sharp, clean edge.

Extended Use & Reliability

After several months of consistent use, this dual-grit sharpener has become an indispensable part of my toolkit. It sees regular action, sharpening everything from a well-worn chef’s knife after a long cooking session to the precise edges of chisels used for detailed joinery. The diamond abrasives show virtually no signs of wear, maintaining their aggressive cutting ability without any discernible flattening.

Durability has been outstanding. The diamond surface remains smooth and effective, with no visible degradation or loss of abrasive power, even after sharpening very hard steels. The continuous zone for smaller tools remains intact and functional, a testament to its robust design. There are no cracks, stiffness, or performance drops to report.

Maintenance is refreshingly simple. A quick wipe-down with a damp cloth after use and occasional scrubbing with a dedicated diamond plate cleaner is all it requires to keep it performing at its peak. Storing it on its base on the workbench means it’s always ready for immediate use, eliminating any excuse for dull blades. Compared to my previous multi-stage system that required careful alignment and had components that wore down quickly, this DMT model offers superior longevity and requires far less attention.

Breaking Down the Features of **DMT Duo Sharp Plus**

Specifications

The DMT Duo Sharp Plus is an 8″ x 2 5/8″ double-sided diamond bench stone, featuring two distinct grits for comprehensive sharpening needs. It is constructed with a diamond abrasive surface, known for its exceptional hardness and ability to sharpen all types of steel. The continuous zone, a key design element, provides an unbroken surface ideal for sharpening small and pointed tools, which is particularly useful for specialized blades.

The inclusion of a Duo Base, a black molded plastic base, is a significant ergonomic enhancement. This base provides a substantial 2″ of knuckle clearance, allowing for comfortable and controlled sharpening without straining your hands or wrists. The rubber feet on the base ensure the entire unit remains firmly planted on your workbench, preventing any slipping or shifting during use.

This unit comes with a rubber handle material and rubber blade material listed in the specifications, which I interpret as referring to the non-slip feet and potentially parts of the base structure itself, providing stability and preventing damage to surfaces. The substantial 8-inch length of the stone offers ample surface area for efficient sharpening strokes, and its 2 5/8-inch width provides a good balance for both wider and narrower blades. This size is considerably larger than many portable sharpeners, making it ideal for stationary use in a workshop or kitchen.

Performance & Functionality

The core function of the DMT Duo Sharp Plus is to sharpen knives and tools effectively, and it excels in this regard. The diamond abrasives provide a consistent and aggressive cutting action, meaning you can remove metal quickly and efficiently to restore a dull edge or create a new one. I’ve found that it can bring even severely neglected blades back to a razor-sharp state with moderate effort.

One of the key strengths of this diamond sharpener is its versatility; it handles both coarse sharpening (for damaged or very dull edges) and fine honing (for achieving a polished, razor-sharp finish) with its two grits. The continuous zone for small tools is not just a gimmick; it genuinely makes sharpening awls, small screwdriver tips, or the points of EDC knives far easier and safer than trying to navigate them on a conventional stone. Its primary weakness, if one could call it that, is the learning curve associated with any sharpening system for those new to maintaining their own edges.

In terms of meeting expectations, this diamond bench stone far exceeds them, particularly when considering its price point. For the durability and consistent performance it offers, the value is exceptional. It outperforms generic sharpening stones that wear down quickly and can be inconsistent, and it rivals more expensive premium sharpening systems in terms of edge quality achievable.

Design & Ergonomics

The design of the DMT Duo Sharp Plus is a blend of functional robustness and user-centric ergonomics. The diamond surface is precisely mounted to the base, ensuring flatness and consistent contact with the blade. The finish on the diamond plates themselves is excellent, with no visible imperfections or areas of uneven grit distribution.

Ergonomically, the Duo Base is a standout feature. The generous 2″ knuckle clearance allows for a comfortable grip on the knife handle without hitting the workbench, which is a common issue with bench stones that lack a raised base. The rubber feet are exceptionally grippy, preventing the sharpener from sliding around, even when applying significant pressure. There’s a slight learning curve in mastering the optimal angle for various blades, but this is inherent to sharpening itself, not a fault of the tool.

Practical design elements like the smooth, unbroken continuous zone are brilliant for intricate tasks. The overall feel of the unit is solid and dependable, suggesting it’s built to withstand frequent, rigorous use.

Durability & Maintenance

Under normal use, the DMT Duo Sharp Plus is built to last a lifetime, a common characteristic of high-quality diamond sharpening stones. The diamond surface itself is incredibly hard and resistant to wear, meaning it will maintain its flatness and abrasive properties for thousands of sharpening sessions. It’s designed for heavy-duty use in workshops, kitchens, and outdoor applications.

Maintenance is minimal, which is a huge advantage. After sharpening, I simply rinse the stone under warm water and use a soft brush to remove any metal particles or residue. For deeper cleaning, a specialized diamond plate cleaner or even a bit of Bon Ami can restore its aggressive cutting action if it ever feels loaded. There are no real failure points to speak of; the diamond surface is bonded to a solid substrate, and the base is made of durable plastic with reliable rubber feet.

Accessories and Customization Options

The DMT Duo Sharp Plus comes with its integrated Duo Base, which is essential for its ergonomic usability. While there aren’t further “customization” options in the traditional sense (like interchangeable parts for the stone itself), the product is designed to be used with a wide variety of knives and tools. The continuous zone acts as a specialized feature that enhances its utility for specific tasks, almost like an integrated accessory for pointed tools.

Compatibility with other accessories is generally limited to standard sharpening techniques. However, the base provides a stable platform for using different sharpening guides or strops if one chooses to augment their sharpening process further. The primary “accessory” is the user’s own collection of knives, which it is designed to service exceptionally well.

Pros and Cons of **DMT Duo Sharp Plus**

Who Should Buy **DMT Duo Sharp Plus**?

This diamond bench stone is ideally suited for home cooks, woodworkers, DIY enthusiasts, and anyone who values a consistently sharp edge on their knives and tools. If you have a collection of kitchen knives that need regular maintenance, or if you use chisels, planes, or other edge tools in a workshop, this sharpener will serve you exceptionally well. It’s also a great choice for individuals who appreciate the durability and low maintenance of diamond abrasives.

Those who should probably skip this product are individuals who primarily need a sharpening solution for field use or travel, as its size and base make it less portable. If you only own one or two very basic knives and rarely use them, the upfront cost might be disproportionate to your needs. People looking for a quick, no-fuss sharpener for a single tool might also find this system more involved than necessary.

For those who do invest in this sharpener, I highly recommend pairing it with a good quality cleaning brush and perhaps a diamond plate cleaner. Having a selection of different knives to test its capabilities on will also help you appreciate its full range of performance.

Conclusion on **DMT Duo Sharp Plus**

The DMT Duo Sharp Plus is, without a doubt, an exceptional sharpening tool that bridges the gap between professional-grade performance and user-friendly design. Its durable diamond abrasives, coupled with the thoughtful inclusion of the Duo Base for improved ergonomics, make it a joy to use. The added benefit of the continuous zone for small tools significantly enhances its versatility, making it a true all-around solution for edge maintenance.

Considering its robust construction, consistent performance, and the longevity of diamond abrasives, the $101.99 price is more than justified. This is not merely a sharpener; it’s an investment in maintaining the performance and usability of your most important cutting tools for years to come.

I would wholeheartedly recommend the DMT Duo Sharp Plus to anyone serious about keeping their blades in optimal condition. If you’re tired of dull knives and unreliable sharpening methods, this unit offers a reliable, efficient, and ultimately satisfying solution.
