[0038] FIG. 4 is a left-front perspective view of scissor razor combination 10 in an open position.

[0039] The following description should be read in view of FIGS. 3-4 and FIG. 9. Blade member tension screw 20 rotatably secures dynamic blade member 17 and static blade member 11 through substantially centered dynamic blade member aperture 40 and substantially centered static blade member aperture 41. Static blade member aperture 41 is countersunk and operatively arranged to accept cone washer 28. Tab 22 comprises tab hook 61, aperture 62, and protrusions 63. The aperture 62 of tab 22 is operatively arranged to accept tension screw 20. Tension screw 20 is secured by lock nut 21. Lock nut 21 comprises a plurality of ridges operatively arranged to contact and frictionally secure lock nut 21 to protrusions 63 on the surface of tab 22. Aperture 62 is operatively arranged to accept tab hook 61 to prevent rotation when threadably secured by tension screw 20 and lock nut 21. Tab aperture 43 may also be a depression operatively arranged to accept tab hook 61 of tab 22.

[0040] The following description should be read in view of FIG. 5 and FIG. 6. FIG. 5 is a left-front perspective view of scissor razor combination 10 in a closed position. FIG. 6 is a right-front perspective view of scissor razor combination 10 in a closed position. Bumper 19 is operatively arranged to contact outer surface of static finger ring 15. Bumper 19 prevents scissor razor combination 10 from closing further to prevent snagging hair if the respective blades were to pass the range restriction created by bumper 19. Bumper 19 also provides a user feedback as bumper contacts the surface of static finger ring 15.

[0041] 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 towards static blade member neck 23 end towards static blade member cutting edge 13. 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 tab 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.

[0042] 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.

[0043] 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.
