IRWIN Tools has introduced its Folding Utility Knife Series with patented BladeLock Technology — the FK100, FK150 and FK250. Recognized for its “best-in-class” design attributes, the FK Series is durable, compact, safe and easy-to-use. The proprietary design addresses the most frequently cited user frustration — when blades accidentally pull out of the handle during use. The BladeLock Technology allows users to change blades only when the release button is engaged and the blade holder is in the 45-degree open position. Each of the new knives has a liner lock for safe, one-handed operation, and a 16-degree cutting angle for ultimate comfort and control. The new FK Series handles are backed by IRWIN’s Lifetime Guarantee. For more information, visit www.irwin.com.
