The OLFA 9mm A-1 Slide-Lock Precision Knife is an affordable, easy-to-use solution for precision knife work. The slim ABS plastic handle fits comfortably into your hand and the handy pocket clip also acts as blade snapper to safely access a new blade segment. The included 9mm AB Precision Silver Snap-Off Blade provides detailed cutting on a variety of materials. The stainless-steel channel secures the blade for safe operation on more challenging cuts. Use the auto-lock slide to move the blade to pre-set cutting depths with audible and tactile clicks at each position. Never waste time on blade changes. This tool features a simple, tool-free blade exchange. Remove the pocket clip, slide the used portion of blade out the back, replace with a new blade, and click the clip back into place. Accepts all OLFA 9mm blades including: A-SOL Silver Solid Blades, AB-S Stainless-Steel Blades, and ABB Ultra-Sharp Black Blades.
