OLFA's Quick-Change Concealed Blade Replacement Head (10 Pack) supports fast maintenance of compatible OLFA concealed-blade cutting tools while minimizing interruptions during repetitive cutting work. Each replacement head is designed around OLFA's quick-change system, allowing users to replace the cutting component when needed rather than replacing an entire safety cutter. The concealed cutting design is particularly useful for opening cartons, trimming packaging materials, and handling film or tape while helping limit direct exposure to the blade. Its compact replacement format makes it practical for keeping spare cutting heads available in toolboxes, supply rooms, packing stations, and distribution areas. With 10 replacement heads included, this package provides a convenient replenishment option for commercial, industrial, and everyday material-handling applications
