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

First Use Experience

I first tested the Demko AD 20.5 Shark-Lock SW Folding Knife during a weekend camping trip in the Appalachian Mountains. Tasks included food preparation, cutting rope for shelter building, and some light wood processing for kindling. The weather was mixed, with periods of sunshine followed by rain showers.

The Demko AD 20.5 Shark-Lock SW Folding Knife performed admirably in both wet and dry conditions. The Grivory handle provided a secure grip even when wet, and the AUS-10A blade held its edge well throughout the weekend. The Shark-Lock proved easy to operate even with gloved hands.

While the blade was sharp out of the box, I found the thumb stud a little stiff initially. It took some breaking in to achieve smooth, one-handed opening. Beyond that, the knife felt comfortable and capable from the start.

My initial surprise was how naturally the Shark-Lock came to me. I had expected a learning curve, but the mechanism is surprisingly intuitive.

After three months of regular use, the Demko AD 20.5 Shark-Lock SW Folding Knife continues to impress. I’ve used it for everything from opening packages to field dressing small game during a recent hunting trip. The knife has proven to be a reliable companion.

The AUS-10A blade has shown excellent corrosion resistance and edge retention. There are minor scratches on the blade’s surface, but no signs of chipping or significant wear. The Shark-Lock remains as solid as day one.

Cleaning the Demko AD 20.5 Shark-Lock SW Folding Knife is straightforward. A simple rinse with water and a wipe down with a cloth is usually sufficient. I occasionally apply a drop of oil to the pivot point to maintain smooth action.

Compared to my previous EDC knives, the Demko AD 20.5 Shark-Lock SW Folding Knife has proven to be significantly more robust and confidence-inspiring, especially when performing demanding tasks. The Shark-Lock gives it an edge over traditional liner locks or frame locks.
