(31) Diverting to FIGS. 7A-8: FIG. 7A shows a cross-sectional front view of static blade member 11 cut along line 7A shown in FIG. 1 without removable razor cartridge 16; FIG. 7B shows a cross-sectional front view of static blade member 11 cut along line 7B shown in FIG. 1 with removable razor cartridge 16 in place in slot 50; FIG. 8 shows a partial left side view of static blade member 11 cut along line 8 shown in FIG. 7A with razor cartridge 16 removed from slot 50. The following description should be read in view of all Figures. Removable razor cartridge 16 holds razor blade 16′. Removable razor slot 50 is centrally disposed in static blade member 11 within the opposite surface of static blade member cutting edge 13. Removable razor cartridge 16 is frictionally secured within removable razor slot 50 by outwardly pushing edges that contact the inner surfaces of removable razor slot 50. Removable razor slot 50 terminates before the tip of static blade member 11 as shown in FIG. 8. Removable razor cartridge 16 substantially straddles the pivot point at tension screw 20 at dynamic blade aperture 40 and static blade aperture 41. Removable razor cartridge 16 is slideably inserted into removable razor slot 50 at the static blade member neck 23 end of slot 50 and slid towards static blade member cutting edge 13 end of slot 50. Removable razor slot 50 extends in length in a direction opposite of the tip of static blade member 11. The length of removable razor slot 50, in the direction opposite static blade member 11 tip and in the direction of hook aperture 43, is shorter than the length of removable razor slot 50 that extends in the direction of static blade member 11 towards the tip, relative to static blade member aperture 41, as illustrated in FIG. 8.

(32) Diverting back to FIG. 2; FIG. 2 shows scissor razor combination 10 held in right hand 100. Dynamic finger ring 14 is operatively arranged to access thumb 104 to hold dynamic blade member 17. Dynamic finger ring 14 is rotatably adjustable to accommodate thumb 104 resting within to the most ideal and comfortable position for a user, reducing fatigue that fixed thumb rings may cause. Static finger ring 15 is operatively arranged to accept middle finger 102. Static finger ring comprises inner finger guard 30 to protect middle finger 102 from sustained use, reducing fatigue from continual use. Neck finger rest 31 is operatively arranged to provide a contoured and ergonomic surface for index finger 101 to rest. Static blade member 11 also includes finger rest 18 that is operatively arranged to optionally allow ring finger 103 to also rest thereon, further improving comfort for a user over prolonged use.

(33) FIG. 10 illustrates the fragmentary cross-sectional view of static blade member 11 shown in FIG. 8. Slot 50 includes closed end 51 and open end 52. Slot 50 is further arranged to extend in leftward direction L relative to static blade member aperture 41 and to extend in rightward direction R relative to static blade member aperture 41. Slot 50 extends in leftward direction L a length L.sub.1 towards open end 52, terminating slot 50 thereat. Slot 50 extends in rightward direction R a length L.sub.2 towards closed end 51, terminating slot 50 thereat. Length L.sub.1 is less than length L.sub.2.

(34) FIG. 11 illustrates a left side view of static blade member 11, specifically illustrating removable razor cartridge 16 disengaged with slot 50, whereas slot 50 is illustrated in broken lines. Static blade member 11 in a preferred embodiment includes blade portion 80 having cutting edge 13, tip 70, and, back edge 84. Back edge 84 is arranged on the opposite side of cutting edge 13. Extending from back edge 84 and cutting edge 13 is neck portion 23A. Neck portion 23A is defined by the section between open end 52 of slot 50 and static finger ring 15 within handle portion 82, specifically including neck 23 and neck finger rest 31. Handle portion 82 includes neck portion 23A, neck 23, neck finger rest 31, specifically neck finger rest 31 is located on the same side as cutting edge 13. Handle portion 82 also includes static finger ring 15 and finger rest 18. As described supra, handle portion 82 is defined by the components that engage fingers 101, 102, and 103 of right hand 100, as shown in FIG. 2. Removable razor cartridge 16 is arranged to be slid into slot 50 from open end 52 in the direction towards closed end 51, engaging slot 50 as illustrated in FIG. 7B. This configuration eliminates the risk of injury related to a razor cartridge being inserted proximate a sharp tip of a blade member.

(35) To use removable razor 16, scissor razor combination 10 is moved to a closed position shown in FIGS. 5 and 6. A user would comb a section or layer of hair and pull removable razor 16 up or down that section or layer to create a textured or feathered look.
