The sharpest, strongest replacement blade knives available for everyday carry with removable/replaceable pocket clip, one-hand opening and six replacement blades. To replace the blade simply push the lock button in the handle to remove and insert a shaving-sharp new blade. The black-oxide coated blade holder supports the razor-blade for the strength of a traditional knife and sharpness of a surgeon’s scalpel. Grivory® (glass/nylon) handles with rubberized color TPR inserts ensure a secure non-slip grip and are available in blaze-orange, blue and gray. Replacement packs of 6-blades are sold separately. US and foreign patents are pending.
