Safety managers will enjoy the multiple safeguards of the 10491 knife: a safer, finger-friendly® blade, automatic retraction to reduce blade exposure, and a familiar handle shape that workers are happy to adopt. While this utility knife ships with a Slice® rounded-tip blade, it’s also compatible with our pointed-tip and serrated-edge blades (10525 and 10523). All blades feature a proprietary edge that’s safe to touch, and an advanced ceramic blade material that never rusts and lasts up to 11 times longer than steel. Store one extra blade in the handle’s onboard blade garage. This ambidextrous model helps lower costs and reduce lacerations.
