No. The UK Penknife Salt is a non-locking slip joint, part of Spyderco's SLIPIT line. A spring holds the blade open with tension, but there is no mechanical lock, so the blade can close if pressure is applied to the spine. Use it for cutting tasks that push the edge away from you, and keep your fingers clear of the edge.

Spyderco originally developed the UK Penknife in response to restrictive knife laws in England that prohibited carrying one-hand-opening locking knives. It combines a pocket clip and Trademark Round Hole with a non-locking mechanism. Knife laws vary by location and change over time, so check your local laws before you buy or carry.

Spyderco's SpyderEdge is a fully serrated edge pattern. The serrations grip fibrous materials, so the blade cuts fishing line, rope, webbing, and cordage where a plain edge tends to slip. To sharpen it, use the corner of a triangle or tapered rod to touch up each serration from the beveled side, then lightly remove the burr on the flat side. Spyderco also offers factory sharpening service.

The UK Penknife Salt is the first non-locking member of Spyderco's Salt Series. It pairs a CPM MagnaCut blade, a powder metallurgy stainless steel designed for very high corrosion resistance, with a marine-grade backspacer and hardware. Rinse the knife with fresh water and dry it after salt exposure to keep it in top condition.

The C94SYL ships as a knife with its reversible deep-pocket wire clip installed. It is knife only, with no sheath included. Packaging and included items are set by Spyderco and are subject to change.
