October 10, 2013 – Irwin Tools introduced the FK100, FK150 and FK250 folding utility knife series, which promises user safety via BladeLock Technology, durability and comfort.

The proprietary design addresses a frequently cited user frustration, says Irwin: when blades accidentally pull out of the handle during use. BladeLock Technology further improves safety by providing the user with the ability to change blades only when the release button is engaged and the blade holder is in the 45º Open position. Each of the new folding utility knives has a liner lock for safe, one-handed operation, and a 16º cutting angle for comfort and control. The FK100 has a built-in wire stripper, while the FK250 sports a fold-out screwdriver for 1-in. insert bits. For added convenience, the FK250 includes built-in blade storage and an additional insert bit storage compartment.
