Demko AD 20.5 Shark-Lock S35VN Black Folding Knife Review

First Impressions of Demko AD 20.5 Shark-Lock S35VN Black Folding Knife

The Demko AD 20.5 Shark-Lock S35VN Black Folding Knife is a folding knife that boasts an innovative locking mechanism and high-quality materials. Manufactured by Demko, it promises strength, reliability, and exceptional cutting performance in a compact package. I’ve been carrying knives for over a decade, everything from cheap gas station folders to high-end custom pieces, and I’m always on the lookout for a blade that can truly stand up to hard use.

I was looking for a durable, reliable EDC (Every Day Carry) knife with a secure locking mechanism and a blade that could hold an edge. My previous EDC knife, while decent, had a locking mechanism that felt a bit flimsy and the blade required frequent sharpening. This led me down a rabbit hole of knife reviews, and the Demko AD 20.5 kept popping up with rave reviews regarding its innovative Shark-Lock and blade steel.

Upon unboxing the Demko AD 20.5, I was immediately struck by the solid feel and purposeful design. The G10 handle provides a secure and comfortable grip, and the stonewash finish on the S35VN blade looks both rugged and refined. The knife feels substantial in hand, without being overly heavy, suggesting a good balance between strength and portability.

I considered the Benchmade Adamas and the Spyderco Paramilitary 2, both highly regarded knives in the EDC world. However, the Demko’s unique Shark-Lock system and the reputation for extreme durability ultimately swayed me. I was drawn to the novelty, and the promise of a lock that was supposedly stronger than a back lock.

My first impression was definitely excitement. The Demko AD 20.5 Shark-Lock S35VN Black Folding Knife felt like a serious tool, and I was eager to put it through its paces. It felt like a step up from my usual EDC options, and the innovative locking mechanism piqued my curiosity.

Real-World Testing: Putting Demko AD 20.5 Shark-Lock S35VN Black Folding Knife to the Test

First Use Experience

I first tested the Demko AD 20.5 during a weekend camping trip in the Appalachian Mountains. The terrain was varied, and I needed a reliable knife for tasks such as preparing food, cutting cordage, and feathering sticks for fire starting. The knife performed admirably in these tasks, with the S35VN blade slicing cleanly through everything I threw at it.

The weather was damp, with intermittent rain showers, and the Demko’s G10 handle provided a secure grip even when wet. The Shark-Lock proved easy to operate with wet or gloved hands, a welcome change from some traditional locking mechanisms that can become slippery in adverse conditions. I did notice that some fine grit found its way into the lock mechanism, requiring a quick rinse later on.

The Demko AD 20.5 was intuitive to use right out of the box. The thumb stud allows for easy one-handed opening, and the Shark-Lock is simple to disengage. There were no unexpected issues or surprises, the knife performed as expected.

Extended Use & Reliability

After several months of daily carry and regular use, the Demko AD 20.5 has held up remarkably well. The S35VN blade has retained its edge exceptionally, requiring only occasional touch-ups with a strop. There are no signs of blade play or loosening of the handle scales.

The stonewash finish on the blade has proven to be quite durable, showing minimal scratching or wear. The G10 handle also remains in excellent condition, with no fading or chipping. The Shark-Lock continues to function smoothly and reliably, inspiring confidence in its strength and security.

Maintenance is simple, consisting of occasional cleaning with a damp cloth and a drop of oil on the pivot and lock mechanism. I’ve found the Demko to be much easier to maintain than some of my previous knives, which required more frequent disassembly and thorough cleaning. Compared to my old EDC knife, the Demko has far exceeded my expectations in terms of edge retention, durability, and overall reliability.

Breaking Down the Features of Demko AD 20.5 Shark-Lock S35VN Black Folding Knife

Specifications

The Demko AD 20.5 Shark-Lock S35VN Black Folding Knife features a 3-inch stonewash finish S35VN stainless clip point blade. The handle is made of durable black G10. It utilizes a thumb stud and thumb pull for ambidextrous opening and the innovative Shark-Lock mechanism for secure blade lockup.

The knife has a closed length of 4 inches and a weight of 0.3 lbs (approximately 4.8 ounces), making it relatively lightweight for its size and robust construction. Additional features include a lanyard hole and a pocket clip for convenient carry options. The choice of S35VN steel is significant because it offers an excellent balance of edge retention, toughness, and corrosion resistance, making it ideal for demanding use.

Performance & Functionality

The Demko AD 20.5 Shark-Lock S35VN Black Folding Knife performs exceptionally well in a variety of tasks. The S35VN blade holds an edge for a long time, requiring minimal sharpening even after extended use. The clip point blade shape is versatile, suitable for both slicing and piercing tasks.

The Shark-Lock is the standout feature, offering a level of security and ease of use that is unmatched by many other locking mechanisms. It’s incredibly strong, virtually eliminating any blade play, and can be easily operated with one hand. The knife excels at cutting, slicing, and piercing tasks. The primary weakness I noticed is that the Shark-Lock can get a bit stiff after prolonged use and require a little extra force to disengage. Despite that, the Demko AD 20.5 has exceeded my expectations in almost every way, proving to be a reliable and high-performing tool.

Design & Ergonomics

The Demko AD 20.5 features a thoughtfully designed and ergonomic handle. The G10 handle provides a secure and comfortable grip, even in wet or slippery conditions. The texturing on the handle is aggressive enough to provide excellent traction without being abrasive.

The knife’s weight is well-balanced, making it comfortable to carry and use for extended periods. The thumb stud and thumb pull allow for ambidextrous one-handed opening, catering to both right- and left-handed users. The design is user-friendly, with no significant learning curve.

Durability & Maintenance

The Demko AD 20.5 Shark-Lock S35VN Black Folding Knife is built to last. The S35VN blade is highly resistant to wear and corrosion, and the G10 handle is virtually indestructible. With proper care, this knife should provide years of reliable service.

Maintenance is straightforward, requiring only occasional cleaning and lubrication. The knife disassembles easily for more thorough cleaning, although this is rarely necessary. I expect this knife to last for many years, based on its robust construction and high-quality materials.

Accessories and Customization Options

The Demko AD 20.5 comes standard with a pocket clip and a lanyard hole, offering versatile carry options. While there are no specific Demko branded accessories available, the knife is compatible with a wide range of aftermarket pocket clips and lanyards.

The knife’s design is relatively straightforward, limiting extensive customization options such as blade swaps or handle modifications. However, the standard components are of such high quality that extensive modifications are unlikely to be necessary. The knife is compatible with most standard-sized lanyards and aftermarket pocket clips that use the same screw pattern.
