Demko AD 20.5 Shark-Lock S35VN CF Folding Knife Review

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

The Demko AD 20.5 Shark-Lock S35VN CF Folding Knife immediately catches the eye with its modern design and promise of robust performance. Demko Knives has built a reputation for innovative locking mechanisms and durable builds, and the AD 20.5 aims to deliver on both fronts. The combination of a premium S35VN steel blade and a carbon fiber handle suggests a knife built for serious use, blending cutting-edge materials with practical functionality.

For years, I’ve relied on various folding knives for tasks ranging from prepping tinder in the backcountry to more mundane EDC tasks. I’ve always sought a blade with a reliable lock, excellent edge retention, and comfortable ergonomics. The AD 20.5’s Shark-Lock mechanism, known for its strength and ease of use, coupled with the promise of S35VN steel’s durability, was a major draw.

The Demko AD 20.5 Shark-Lock S35VN CF Folding Knife arrived in a simple box, nothing fancy, which I appreciate – it’s about the tool, not the packaging. The knife felt substantial in hand, but surprisingly lightweight thanks to the G10 handle scales. The stonewash finish on the blade looked rugged and ready for hard work, and the action was smooth right out of the box.

Compared to my Benchmade Griptilian and Spyderco Paramilitary 2, the AD 20.5 felt different. The Griptilian is a classic, known for its light weight and Axis lock, while the Paramilitary 2 is a cutting machine with a great ergonomic design; however, neither of them has the unique Shark-Lock of the Demko AD 20.5 Shark-Lock S35VN CF Folding Knife. This difference is what ultimately led me to choose the Demko.

My initial impression was one of excitement and anticipation. This Demko knife felt like a serious tool, promising a level of performance and reliability that could easily make it my new go-to folder.

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

First Use Experience

My first field test for the Demko AD 20.5 Shark-Lock S35VN CF Folding Knife was a weekend backpacking trip in the Appalachian Mountains. I needed to process firewood, prepare food, and perform general camp tasks. The weather was typical for the area – damp, with occasional light rain.

The knife handled the tasks admirably. The S35VN blade sliced through wood with ease, making feather sticks for fire starting a breeze. The Shark-Lock proved incredibly easy to operate even with wet and cold hands. I was impressed by the secure grip, even when the G10 handle was slightly damp.

One initial surprise was how well the clip point blade worked for detailed carving. I was expecting it to be more of a general-purpose blade, but it excelled at finer tasks. No issues arose during the first use, and the knife maintained its edge throughout the weekend.

Extended Use & Reliability

After several months of consistent use, the Demko AD 20.5 Shark-Lock S35VN CF Folding Knife continues to impress. I’ve used it for everything from opening boxes to cleaning fish on a recent fly-fishing trip. The knife has become an indispensable tool in my everyday carry.

Durability has been exceptional. There are no signs of blade play, and the Shark-Lock remains as solid as day one. The stonewash finish hides scratches well, so the blade still looks relatively new.

Maintenance is straightforward. I simply rinse the blade after use and occasionally apply a drop of oil to the pivot. So far, I have not needed to sharpen the blade, which speaks to the quality of the S35VN steel and Demko‘s heat treatment. Compared to other knives I’ve owned, the AD 20.5’s edge retention is noticeably superior.
