Spyderco UK Penknife Salt – a lightweight slip-joint folding knife for everyday use
Spyderco UK Penknife Salt Yellow FRN, CPM MagnaCut by Sal Glesser (C94PYL) is a modern EDC folding knife from the Salt® series, designed for low weight, high corrosion resistance, and comfortable use in everyday conditions. The model features a lockless Slip Joint / SLIPIT® design, a blade made of CPM MagnaCut steel, a handle made of yellow FRN, and the distinctive SpyderHole, which makes it easy to open the blade.
The Salt variant stands out for its materials, which are selected for use in humid environments, during outdoor activities, near water, or in everyday use requiring easy maintenance. The bright yellow color improves the knife’s visibility, and the lightweight construction and deep-carry wire clip make the UK Penknife Salt a great choice as a discreet pocket folding knife.
CPM MagnaCut – Premium Corrosion-Resistant Steel
CPM MagnaCut is a modern powder-metals steel developed to combine high corrosion resistance, good strength, and cutting edge durability. In the UK Penknife Salt model, it performs well in tasks typical of a lightweight EDC knife: cutting tape, cardboard, cord, plastic wrap, packaging, and everyday materials.
In the Salt® design, CPM MagnaCut steel works in tandem with materials resistant to moisture and outdoor conditions. This makes the knife a convenient choice for those who want to minimize the need for frequent maintenance while maintaining high cutting quality and resistance to environmental factors.
Leaf-Shaped and Full Flat – Control and Cutting Efficiency
The Leaf-Shaped profile is a blade geometry characteristic of Spyderco, featuring a wide working section and a precise tip. This design ensures good control during cutting, works well for precision tasks, and allows you to utilize a significant portion of the cutting edge’s length.
The Full Flat grind facilitates smooth gliding of the blade through the material and reduces resistance during cutting. The blade features a Satin finish, which emphasizes its technical, functional design. The serrations on the spine and the notch for the index finger enhance grip control, especially during more precise work with the blade.
Yellow FRN and Salt® construction—lightweight and durable
The handle, made of FRN (Fiberglass Reinforced Nylon), combines low weight, moisture resistance, and the durability essential for everyday use. The textured surface improves grip, and the bright Yellow color helps you quickly find the knife in your backpack, toolbox, on a boat, or out in the field.
The materials used in the Salt® model were selected for their resistance to high-humidity environments. The reversible wire clip Left / Right, Tip-Up allows for comfortable carrying of the knife on either side of your pocket, and its slim profile minimizes the knife’s visibility when carried.
Slip Joint / SLIPIT® – a lockless design with the SpyderHole opening mechanism
The Slip Joint / SLIPIT® mechanism uses spring tension to hold the blade in both the open and closed positions, but does not mechanically lock it. This design requires conscious handling of the knife and control over finger placement when cutting and folding the blade.
The SpyderHole allows you to conveniently open the blade by hand, even while wearing gloves or with wet hands. The absence of a traditional lock may mean that the knife complies with regulations in many countries where restrictions on locked knives are in place; however, you should always check local laws before carrying it.

Frequently Asked Questions
How do I care for and sharpen CPM MagnaCut steel?

The lack of a traditional lock may mean that the knife meets the requirements in many countries with restrictions on locks. However, you should always check local laws and how they are enforced before carrying it.
What is the SpyderHole for?
The SpyderHole makes it easy to open the blade with one hand. The hole provides a secure thumb rest and is comfortable to use even with wet hands or while wearing gloves.
