The silver-and-black color combination not only provides a modern appearance but also improves visibility. At the end of the handle, there is a hanging / safety hole for lanyards. -High-Performance SK2 Blade: Equipped with an 18 mm SK2 snap-off blade, this knife effortlessly cuts through thicker materials such as drywall, linoleum, carpet, rubber, leather, and much more. When the blade becomes dull, simply snap off the used segment to reveal a fresh sharp edge. The durable blades combined with the metal body make the L704 the ideal tool for professional craftsmen. -SINSEUNG Quality Since 1965: Trust in over 60 years of experience from the Korean manufacturer SINSEUNG.

This 18 mm snap-off knife was specifically designed for heavy-duty cutting tasks and continuous professional use. The most noticeable difference compared to conventional utility knives is the handle material: the L704 features a zinc-aluminum alloy body, making it significantly more robust and resistant to impacts or accidental drops. The additional weight of approximately 70 g provides outstanding stability in the hand – the knife feels solid in the palm and enables highly controlled cuts with minimal effort, as the knife’s own weight supports the cutting motion. Despite its metal construction, comfort is not compromised. The ergonomic rounded design and strategically placed textured grip ensure safe and slip-resistant handling. The two-tone silver and black finish is not only visually appealing but also makes the tool easy to identify quickly in a toolbox. Of course, this model also includes an integrated auto-lock mechanism that securely fixes the blade in any position. Once the desired blade length is adjusted, it remains firmly locked in place – ideal for cutting through tough materials such as roofing felt, PVC flooring, or thick tarpaulins without the blade slipping back. If a blade segment becomes worn, simply use the removable end cap as a lever to safely snap off the used segment. Thanks to the snap-off function, you instantly have a fresh cutting edge ready to use without opening the knife. The SINSEUNG L704 combines the advantages of a metal utility knife with proven snap-off blade technology. It is ideal for applications where conventional plastic utility knives reach their limits, such as drywall work, flooring installation, cutting rigid plastics, or multi-layer cardboard. SINSEUNG – one of South Korea’s leading cutting tool manufacturers since 1965 – stands for quality and reliability. Every L704 utility knife undergoes strict quality control to ensure it can withstand demanding daily use. Whether you are a professional craftsman or an ambitious DIY enthusiast, the L704 is a premium tool built to last for years and handle even the toughest cutting tasks with ease. | Feature | Specification | | ----------------- | ----------------------------------------- | | Model | L704 (18 mm Heavy-Duty Utility Knife) | | Blade Type | 18 mm Snap-Off Blade (8 segments, SK2) | | Locking Mechanism | Automatic Blade Lock (Auto-Lock) | | Handle Material | Zinc Alloy (Metal Body), Steel Inner Rail | | Total Length | Approx. 160 mm | | Weight | Approx. 70 g | | Color | Silver / Black |
