➡️Design and Build Quality

Tenable Prometheus Folding Knife

The Tenable Prometheus Folding Knife is designed to offer both style and functionality. Its design elements are crafted to enhance the user experience while maintaining aesthetic appeal.

Blade Length and Overall Size

With a blade length of approximately 3.25 inches and an overall length of 7.12 inches, the Prometheus strikes a balance between compactness and usability. This size is ideal for both everyday carry (EDC) and various cutting tasks.

Blade Shape and Finish

The blade features a sheep’s foot design, which is excellent for precision work and controlled cuts. The black wash finish not only adds a sleek look but also helps conceal scratches and wear. For those who prefer different finishes, the Prometheus is available in satin and tumbled options.

Handle Material and Construction

The handle is made from layered G10, which consists of a black G10 layer over a red G10 base. This layering not only enhances the knife’s appearance but also improves its grip and durability. The handle’s red pivot collar adds a unique touch, setting the knife apart from other models in its price range.

Ergonomics

While the Prometheus offers a solid grip, the pocket clip’s placement may cause minor discomfort during prolonged use. The clip can be a bit long for some users, and its positioning may not be ideal for extended cutting tasks.

➡️Blade Steel and Performance

The choice of blade steel significantly impacts a knife’s performance. The Tenable Prometheus Folding Knife uses 14C28N steel, a popular option in the budget knife category.

Edge Retention and Toughness

14C28N is known for its balanced performance, offering a good mix of edge retention, toughness, and corrosion resistance. While it may not match premium steels in edge retention, it performs well enough for most everyday tasks.

Maintenance

One of the advantages of 14C28N is its ease of maintenance. It resists corrosion and is relatively simple to sharpen, making it a practical choice for users who prefer low-maintenance knives.

➡️Build and Construction

Tenable Prometheus Folding Knife

The Tenable Prometheus Folding Knife boasts several key construction features that enhance its overall functionality and durability.

Handle and Clip

The titanium pocket clip is a notable feature in this price range. Although the clip is well-made, its length and design may not be the most comfortable for all users. Additionally, the handle features steel liners, which add weight but contribute to the knife’s overall sturdiness.

Pivot and Hardware

The knife’s pivot is a T8, which is generally a robust choice. However, the pivot has a tendency to spin freely, which can be inconvenient during maintenance. The body screws are T6, and the knife lacks a left-handed clip mount, which could be a limitation for left-handed users.
