Real-World Testing: Putting Extrema Ratio NK1 Neck Knife to the Test

First Use Experience

I primarily tested the Extrema Ratio NK1 Neck Knife during a week-long backcountry hiking trip in the Cascade Mountains. The conditions ranged from sunny and dry to damp and foggy. The knife was used for various tasks, including food preparation, cutting cordage, and whittling tinder for fire starting.

The Extrema Ratio NK1 Neck Knife performed admirably in all conditions. The Bohler N690 steel blade held its edge well even after repeated use. Its small size took a bit of getting used to, but the handle design provided a secure grip, even with wet hands.

One minor issue was the Kydex sheath initially felt a bit tight, making drawing the knife slightly difficult. However, after a few days, the retention loosened up to the perfect level, allowing for quick and reliable deployment.

Extended Use & Reliability

After several months of regular use, the Extrema Ratio NK1 Neck Knife has proven to be a reliable and durable tool. There are no signs of significant wear and tear on the blade or handle. The Kydex sheath continues to function flawlessly.

Cleaning and maintaining the Extrema Ratio NK1 Neck Knife is straightforward. The stainless-steel construction resists corrosion and cleans easily with soap and water. Compared to my previous experiences with cheaper neck knives, the NK1 far exceeds expectations in terms of durability and edge retention.
