DMT Double Sided Diafold Sharpener Review

Here’s What You’ll Love (or Not) About the DMT Double Sided Diafold Sharpener

For years, I’ve relied on a variety of sharpening tools to keep everything from kitchen knives to workshop chisels at their peak. My search for an efficient, portable, and durable sharpener led me to the DMT Double Sided Diafold Sharpener. This particular model from DMT promised a two-stage sharpening system in a compact, folding package. I was particularly intrigued by the mention of the Hardcoat Surface, designed for extra durability when sharpening ceramic blades, a material I’ve encountered in both workshop and some specialized outdoor gear.

My decision to acquire this sharpener stemmed from a specific need for a reliable, go-anywhere sharpening solution. I often find myself needing to touch up edges in less-than-ideal conditions – be it out in the field, at a remote workshop, or even just to maintain tools in my car’s emergency kit. Conventional sharpening stones can be bulky and messy, and many portable sharpeners lack the grit range and durability for serious use. Considering brands like Lansky and Work Sharp, I opted for DMT’s diamond technology, known for its effectiveness on a wide range of materials.

Upon unboxing, the sharpener felt solid despite its lightweight construction. The folding handles, made of durable plastic, immediately gave the impression of a tool designed for the rigors of frequent use. It’s a practical piece of kit, not overly fancy, but built with clear intention. My initial impression was one of quiet competence; this wasn’t a tool that screamed for attention, but rather one that quietly promised to get the job done effectively.

My first real test came with a paring knife that had seen better days. The feel of the diamond surface under the blade was immediate and satisfying. It was clear this wasn’t going to be a slow, laborious process. There was an immediate sense of relief, knowing I had a capable tool ready for immediate action without fuss or extensive setup.

Real-World Testing: Putting DMT Double Sided Diafold Sharpener to the Test

My testing grounds for the DMT Double Sided Diafold Sharpener have been varied and, frankly, a little unforgiving. I’ve used it on my workbench, in my gardening shed, and even brought it along on a week-long camping trip where maintaining sharp edges on utility knives is crucial. The convenience of the folding design meant it was always accessible, tucked away in a pocket or tool roll without adding significant bulk.

During the camping trip, I subjected it to more than just routine sharpening. Exposure to light dust and the occasional drop on a packed dirt campsite were part of the experience. Despite these conditions, the diamond abrasives held up remarkably well, and the folding handles remained secure, protecting the sharpening surfaces. The ease of use was a standout feature; there was virtually no learning curve, and I could achieve a respectable edge on a utility knife within a minute or two, even with cold hands.

After several months of consistent use, this sharpener has proven its mettle. It’s become my go-to for quick edge maintenance on a variety of blades, from my EDC pocket knife to small carving tools. The diamond surfaces show no discernible wear, and the folding mechanism still operates smoothly and locks firmly into place. Compared to ceramic rods I’ve used in the past, the diamond plates on this DMT sharpener cut faster and maintain their abrasive quality for far longer. Maintenance is straightforward: a quick rinse with water is usually all that’s needed to clear away any metal filings.

Extended Use & Reliability

The DMT Double Sided Diafold Sharpener has easily endured months of consistent, if not heavy, use. My workshop sees a variety of steels, from softer carbon steels to harder tool steels, and this sharpener handles them all without complaint. I haven’t observed any significant wear on the diamond grit, which speaks volumes about DMT‘s manufacturing quality. The folding handles, a crucial element for its portability, continue to function flawlessly, providing a secure grip when open and protecting the abrasive surfaces when closed.

Cleaning is as simple as it gets: a quick wipe with a damp cloth or a rinse under running water usually suffices to remove any swarf. For more stubborn residue, a bit of dish soap does the trick. Storing it is also effortless due to its compact, folding nature; it slides easily into any drawer, toolbox, or pack. When compared to my previous experience with traditional sharpening stones, which require careful storage to avoid chipping and wear, this sharpener is a dream to maintain.

Breaking Down the Features of DMT Double Sided Diafold Sharpener

Specifications

The DMT Double Sided Diafold Sharpener is a compact, two-stage sharpening system featuring monocrystalline diamond abrasives. It boasts a Fine diamond surface (25 micron / 600 mesh) for establishing a sharp edge and an Extra-Fine diamond surface (9 micron / 1200 mesh) for refining and polishing that edge to a razor sharpness. The product dimensions are a closed length of 5 inches and an open length of 9.5 inches, making it exceptionally portable. The handles are constructed from durable plastic, enclosing and protecting the sharpening stones when folded. The continuous surface design of the diamond plates is advantageous for sharpening both standard edges and smaller, pointed tips.

These specifications translate directly into practical benefits for the user. The dual-grit system means users don’t need multiple stones for basic sharpening and honing; one tool can perform both tasks effectively. The compact, folding design is perfect for anyone who needs to sharpen tools on the go, eliminating the need for bulky sharpening kits. Furthermore, the Hardcoat Surface offers enhanced durability, particularly important when sharpening notoriously hard materials like ceramic blades, ensuring a longer lifespan for the sharpener itself.

Performance & Functionality

In its primary role, the DMT Double Sided Diafold Sharpener performs exceptionally well. The Fine grit quickly removes material, allowing for efficient reshaping of dull edges or even repairing minor nicks. Moving to the Extra-Fine grit then refines this edge to a level of keenness that is genuinely impressive for such a portable device. It truly sharpens in a fraction of the time required by conventional sharpening stones, making it ideal for field expediency or quick touch-ups.

The main strength of this diamond sharpener lies in its aggressive yet controlled cutting action. It cuts hard steels and ceramics with equal efficiency, a notable advantage over many other sharpening mediums. Its primary weakness, if one can even call it that, is its size; while portable, it’s not designed for very large blades that might require longer sharpening strokes. However, for knives, multi-tools, small chisels, and even gardening tools, its performance is outstanding, meeting and often exceeding expectations given its form factor and price point.

Design & Ergonomics

The design of the DMT Double Sided Diafold Sharpener prioritizes functionality and portability. The folding plastic handles are robust and provide a comfortable grip when the sharpener is open, enclosing the diamond plates securely when not in use. The contrast between the textured plastic handle and the abrasive diamond surface creates a tactile experience that aids in control during sharpening.

Ergonomically, it’s a pleasure to use. The 5-inch closed length makes it easy to slip into a pocket or bag, and the 9.5-inch open length provides adequate leverage for most sharpening tasks. The continuous surface on the diamond plates is a subtle but important design element, allowing for sharpening of a wide variety of edge types without obstruction. There’s no real learning curve; the process is intuitive and mirrors traditional sharpening methods but with greater speed and less mess.

Durability & Maintenance

The DMT Double Sided Diafold Sharpener is built for longevity, a hallmark of DMT products. The monocrystalline diamond surface is incredibly hard and resistant to wear, meaning it should maintain its abrasive properties for many years, even with regular use. The Hardcoat Surface further enhances this durability, particularly if you intend to sharpen ceramic blades frequently.

Maintenance is minimal, which is a huge advantage. Unlike oil stones that require soaking and specific cleaning agents, or water stones that can develop “dishing” and require flattening, diamond sharpeners are remarkably low maintenance. A simple rinse with water and mild soap to remove metal residue is usually sufficient. DMT recommends sharpening dry or with water, avoiding oil, which simplifies the process and eliminates potential mess. I’ve experienced no failure points thus far; the hinges are solid, and the diamond surface remains true.

Accessories and Customization Options

The DMT Double Sided Diafold Sharpener comes as a self-contained unit, with no additional accessories included. However, its design is highly compatible with standard sharpening practices and, importantly, is designed to work effectively without any special add-ons. The two distinct grits (Fine and Extra-Fine) effectively cover the common sharpening needs for most users, eliminating the necessity for separate honing tools in many situations.

While there are no direct customization options for the sharpener itself, its strength lies in its versatility. It can sharpen a vast array of tools, making it a valuable addition to any toolkit rather than a piece requiring complementary parts. The continuous surface is arguably its most significant “feature,” allowing it to accommodate a wide range of blade profiles and sizes without issue.

Pros and Cons of DMT Double Sided Diafold Sharpener

Who Should Buy DMT Double Sided Diafold Sharpener?

This sharpener is an excellent choice for outdoor enthusiasts, campers, hikers, and anyone who needs a reliable sharpening tool away from home. Home DIYers, woodworkers, and even chefs who want a quick way to touch up their knives between full sharpening sessions will find it invaluable. It’s also a perfect addition to any emergency preparedness kit or vehicle tool roll.

Individuals who primarily sharpen very large blades (e.g., machetes, large cleavers) might want to consider a larger sharpening system. Also, those who prefer a very traditional sharpening experience with natural stones may find the diamond abrasive feel different. For those seeking a simple, effective, and portable solution for maintaining sharp edges on everyday tools, this is an outstanding option. Consider pairing it with a good quality microfibre cloth for cleaning and a small pouch to protect it further during transport.
