This is the closest you can get to a street legal switch-blade. With spring-assisted technology, the SPIDER deploys quickly and easily with one hand. This razor-sharp knife can be deployed using the index finger for a sudden release of the blade by flipping the lever at the top of the knife. Of course, when a job calls for more deliberate actions, you can also open this knife in the traditional way, using the thumb stud. The SPIDER SPRING-ASSIST KNIFE features a high carbon 440 stainless steel blade that stays sharp long. A sharp knife is not only more useful than a dull knife, it's also safer to use. With a strong, sharp blade and lightweight aluminum handle, you can make the cuts you want quickly and efficiently. Whether you're finishing up a weekend around the house or heading up a mountain rescue operation, this strong yet lightweight and easy-to-use knife features a richly colored SPIDER design which is a fun and unique. The SPIDER is a knife that you can be proud to own and will give you long lasting pleasure.
