     BRIEF DESCRIPTION OF THE INVENTION 
     This invention involves ergonomically efficient, hand-held frost cutter and ice breaker assemblies. The frost cutter assembly incorporates a comfort (filler) washer between its upper bottle portion and its lower frost cutter portion. The ice scraper assembly has a finger protector guard between its bottle and ice breaker portion. Both the comfort washer and finger protector are interchangeable and have open space for assembling their respective structures. The bottle top has structures/protrusions or recessed, curved, concave surfaces with adjacent beveled surfaces, which are raised compared to said adjacent, curved concave surfaces, to aid in gripping same and lessening the force required to be exerted by the user, thus increasing the ergonomic efficiency of the devices. These devices can be fitted with bug remover fabric mesh associated with a foam backer and fitted onto &#34;O&#34; ring recesses using rubber &#34;O&#34; rings. The bottles can have a top, flat surface containing a logo or advertising placed thereon. Preferably the bottle portion can be clear plastic, viz., substantially transparent. 
     These devices are small and can be easily stored.

     DETAILED DESCRIPTION OF THE INVENTION 
     As can be seen from the isometric views of FIGS. 5 and 6, FIG. 5 shows the bottle, comfort (filler) washer, and frost scraper assembly (10). FIG. 6 illustrates the bottle, finger protector guard and ice breaker assembly (10&#39;). The comfort (filler) washer (11) is shown in FIG. 1. FIG. 2 shows finger protector guard (11&#39;). 
     The cross-sectional view of the comfort (filler) washer (12) is shown in FIG. 3 having its beveled inner surface (13) and curved outer surface (14). 
     FIG. 4 of the drawings shows finger protector guard (12&#39;) having its beveled inner surface (13) and curved outer surface (14). Both the comfort (filler) washer and finger protector guard have open space (15) for assembling their respective structures FIGS. 1, 2, 5 &amp; 6. Frost cutter solution containment base (35) has its lower solid portion (16) as shown in FIG. 5. Correspondingly, ice breaker solution containment base (36) has its lower solid portion (16)&#39; as shown, for example, in FIG. 6. FIGS. 5 &amp; 6 each show a bottle (17) with a bottle top flat surface (19) having placed thereon a logo (18). This arrangement is shown in FIGS. 5 through 8. FIG. 9 shows the bottom surface (20) of the frost cutter base and FIG. 10 shows the bottom surface (20&#39;) of the ice breaker base. 
     The scraper base flutes can be seen in cross-section from lines 11--11 of FIG. 9 whereas the ice breaker flutes can be seen from section lines 12--12 of FIG. 10. 
     FIG. 11 shows the frost cutting scraper flutes (22) as composed of scraper flutes base (23) and scraper flutes triangular extended portions (24) as shown from FIG. 11. This semi-flexible frost cutter accommodates glass surfaces, whether concave or convex. For example, the semi-flexible frost cutter can be used on the concave windshields on the outside and also on the convex surface windshields on the inside. These flutes can be made of semi-flexible polyethylene or equivalent plastic material. 
     The ice breaker round, semi-circular, convex, extended portions (24&#39;) can be made of hard polyethylene or equivalent plastic material. They are shown in FIG. 12 as having their lower base portions (23&#39;) and convex, semi-circular extended portions (24&#39;). 
     Frost cutting flutes (22) (sectioned) can be seen in FIG. 11 whereas ice breaker flutes (24&#39;) can be shown sectioned in FIG. 12. The scraper flute base (23) and the ice breaker flutes base (23&#39;) are shown, respectively, in FIGS. 11 and 12. 
     As will be noted from FIG. 11 the semi-flexible frost cutter has scraper flutes which are triangular extended portions to accommodate glass surfaces, whether concave or convex. Thus they can be used on the concave windshields on the outside as well as on the convex surface windshields on the inside. The round, semi-circular, ice breaker flutes have extended portions (24&#39;) extending from their respective bases (23&#39;). 
     The bottles of both the frost cutter and the ice breaker assemblies can, and usually do, contain a solution to aid in dissolving road film on the inside and/or outside of the window. These bottle assemblies have a lower bottle portion (25) having a flared rim (27) and downwardly beveled sections (28) located beneath the respective flared rims (27) of each lower bottle portion. As will be noted from FIGS. 15 and 16, the downward bevel of each bottle lower portion is below its flared rim (27). Beneath each respective beveled portion (28) there are male threads (26) which are substantially parallel, yet slanted. This structure is apparent from FIGS. 13 through 16. 
     The outer surfaces of the bottle portions above flared rim (27) have exterior portions which aid in gripping said bottle portions. Thus FIG. 15 illustrates convex, semi-circular protrusions (29) for this purpose and the structure of FIG. 16 illustrates the use of recessed, curved, concave surfaces and adjacent, beveled surfaces, which are raised compared to said adjacent, curved, concave surfaces, as shown at (30) to likewise aid gripping same and lessening the force required to be exerted by the user, thus increasing the ergonomic efficiency of the devices. 
     The devices of this invention can be fitted with bug remover fabric mesh, as is shown in FIG. 17. Such bug remover fabric mesh can have an inner portion (31) and an outer portion (32) as shown in FIG. 17. This bug remover fabric mesh can be fitted on to &#34;O&#34; ring recesses (33) such as are shown in FIGS. 5, 6, 7, 8, 13 &amp; 14. The &#34;O&#34; rings, themselves, (34) can be made of rubber, or equivalent material. 
     FIG. 17 shows the bug remover fabric covering composed of inner fabric mesh portion (31) and outer fabric mesh portion (32) which are wrapped around rubber &#34;O&#34; ring (34) and foam backer (37) to be fitted onto the lower portion of the frost cutter and/or the ice breaker by placement of the rubber &#34;O&#34; ring (34) within its appropriate &#34;O&#34; ring recess (33). 
     Shade lines 38 are shown in FIGS. 15, 16 &amp; 17. 
     In accordance with a preferred embodiment of this invention, the bottle portion of the assembly can be clear plastic, viz., substantially transparent. Thus this invention provides ergonomically efficient, hand-held frost cutter and ice breaker assemblies. The frost cutter assembly incorporates a comfort (filler) washer between its upper bottle portion and its lower frost cutter portion. The ice scraper assembly has a finger protector guard between its bottle and ice breaker portion. Both the comfort washer and finger protector are interchangeable and have open space for assembling their respective structures. The bottle top has structures (protrusions or recessed, curved, concave surfaces with adjacent beveled surfaces) which are raised compared to said adjacent, curved concave surfaces, to aid in gripping same and lessening the force required to be exerted by the user, thus increasing the ergonomic efficiency of the devices. These devices can be fitted with bug remover fabric mesh associated with a foam backer and fitted onto &#34;O&#34; ring recesses using rubber &#34;O&#34; rings. The bottles can have a top, flat surface containing a logo or advertising placed thereon. Preferably the bottle portion can be clear plastic, viz., substantially transparent. 
     These devices are small and can be easily stored.
