This product is a retractable trimming knife supplied with five spare blades, designed for controlled cutting and trimming tasks in trade and DIY settings. It is primarily used for cutting wallpaper, carpet and vinyl edges, trimming insulation and roofing felt, opening cartons, and precise slicing where reach and safety are important. The retractable mechanism allows the blade to be locked safely when not in use, reducing the risk of accidental cuts.

The knife features a robust handle moulded from impact-resistant ABS with a rubberised overmould for improved grip and user comfort. Blades are supplied in a set of five and are manufactured from SK5 high‑carbon steel (honed to a sharp edge and chemically treated for improved corrosion resistance). The blade cartridge accepts standard 18 mm trapezoidal utility blades, making it compatible with commonly available replacement blades. The slider mechanism is a positive index type for incremental blade extension and retraction; there are no threaded parts or drive heads on this product.

While there is no single universal standard for this style of hand knife, the trimming knife is produced to Draper Tools Group quality controls and carries applicable CE/UKCA conformity marking where required for hand tools and mechanical safety. The materials and finish provide good edge retention from the high‑carbon blades and a durable, wear‑resistant handle suitable for site environments.

Typical users include decorators, carpet fitters, electricians, plumbers and general builders who need a reliable, compact cutting tool that is safe to carry in a pocket or tool belt. The knife is equally suited to craft studios and light industrial use where repeatable, accurate trimming is required. Key benefits are the convenience of the retractable, lockable blade for safety, the compatibility with standard 18 mm blades for easy replenishment, and the balance of edge life and corrosion resistance from the treated SK5 steel.

Duchy Fasteners stocks this trimming knife in single units and in multi‑packs; replacement blades are sold separately in packs to suit trade and contractor usage. For specific size or pack enquiries please contact our sales team.
