     Referring to the drawings, more specifically to FIG. 2, which is a fragmentary perspective view of the present preferred embodiment, wherein there is shown the multi-functional stationery tool combination comprising four principle parts which are the top casing (1), top guiding plate (2), bottom casing (3) and bottom guiding plate (4). 
     As shown in FIG. 2, the top casing (1) has a rectangular shape. A horizontal depression (10) is provided on the surface of casing (1) and a long and narrow opening (101) having wave-like structure (102) at one of the longer edge therein is provided through casing (1). 
     Adjacent the bottom of the opening (101), is a recess (not shown) adapted to receive a blade (N) having a hole (N1) at one end thereof. By means of a roundhead fastening nut (11), the blade (N) is connected to a slidable base (12) with said fastening nut (11) extending through said opening (101) and hole (N1) of said blade (N). The blade (N) is therefore, closely received against the recess (not show) beneath said opening (101). The slidable base (12) is slidably provided on the top guiding plate (2) having protruding edge (20) on the surface thereof. The slidable base (12) is slidably engaged at one side of said protruding edge (20) so that the displacement of the blade (N) can be controlled. Further, a fixation hole (21) is provided such in plate (2) that a staple removing device (R) can be disposed by any fastening nut or screw, onto said top casing (1). 
     Reference is now made to FIG.2 and FIG. 1. A stepped platform (23) is formed on said top guiding plate (2), wherein a retractable measuring tape (M) (as shown in FIG. 1) is provided within a space formed in between said stepped platform (23) and the bottom of top casing (1). The action of the retractable measuring tape is controlled by a retrieving control element (24) such that when said tape (M) is extended, it can be returned to its original position. 
     The bottom casing (3) and guiding plate (4) substantially have the same shape as that of the top casing (1) and guiding plate (2). An L-shaped opening (40) is provided on said bottom guiding plate (4). Adjacent to said opening (40), protruding element (41) are provided for the fixation of a pencil sharpener (S) having a container (5) for collecting pencil debris (not shown). The container (5) is open at one side (50) facing the debris dischanging side (not shown) of aid sharpener (S), such that the debris can be collected. When the collected debris is at a maximum amount, a slidable cover (51) provided on said bottom guiding plate (4) is slid out from said container (5) and thus, the debris can be dischanged. Further, two horizontal slots (42) (43) are provided adjacent the opening (40). Slots (42) and (43) correspond to the slots (25) and (26) of said top guiding plate (2). The pair of slots (42) and (25) is for the engagement of a storage box (6) having two protruding knobs (60) at one end thereof such that the storage box (6) can be slid in and out in the direction of the arrows as shown in FIG. 3. The storage box (6) is used to keep small articles such as pins or paper-clips, within an opening space (61) of said box (6). The pair of slots (43) and (26) is for the engagement of stapler (B) having engaging elements (B2) at the base (B1) thereof. The function of these slots (43), (26) are the same as that of slots (42), (25), therefore, the stapler (B) can be slid in and out within the slots (43), (26). A partition plate (48) having protruding element (441) is provided adjacent the opening space (61) such that when the stapler (B) is withdrawn, articles within the opening space(61) will not be thrown out. 
     In between said stapler (B) and said container (5), a paper punch (C) is mounted. The punch (6) includes a base (C1) (top of FIG 2), a punching element (C2) and a pressing element (C3), wherein said base (C1) is substantially rectangular in shape and is mounted at the lateral edge of said top and bottom casings (1), (3). The punching element (C20) at the center of base element (C2), contacts the pressing element (C3) in order to punch a hole in paper. A pair of protruding blocks (C7) are each oppositely provided on the lower edge of said punching element (C2) so that said punching element (C2) can be firmly disposed on slits (29), (49) of said top guiding plate (2) and bottom guiding plate (4). One protruding block (C7) is respective fixed into each of the slits (29) and slit (49) which have the same thickness as that of said protruding blocks (C7). Two square shaped protrusions (C30) are provided on the lateral sides of said pressing element (C3) so that said element (C3) can be respectively engaged into a rectangular slot (44) of said bottom guiding plate (4) and a rectangular slot (27) of said top guiding plate (2), such that said pressing element (C3) is slidable within the slots (27), (44), when the pressing element (C3) is pressed down in a direction perpendicular to the base (C1), a hole will be made in a sheet of paper (not shown) in between said pressing means (C3) and said punching element (C20). Further more, a knife (D) is pivotally mounted onto said bottom guiding plate (4), such that knife (D) is mounted with an axis corresponding to the mounting axis of said stapler removing device (R). A depression (30) is made on said knife (D) so that said knife (D) can be easily extended about the axis of mounting. 
     As shown in FIG. 2, a protruding periphery (32) is provided around a long opening (31). Periphery (32) has a certain thickness for the storage of a pair of scissors (A). As shown in the same figure, said pair of scissors (A) is formed from two scissor blades (A1) having a hole (A11) at one end thereof and a notch (A10) formed on the edge of said scissor blades (A1) near the one end. A U-shaped elastic spring (A2) having a hook (A20) at both ends thereof so that said spring (A2) can be engaged with said notch (A10) is provided on said scissor blades (A1). The scissors (A) is mounted to said L-shaped opening (40) of said bottom plate (4) by means of a fixation element (A3) after passing through said opening (A11) of said scissors blades (A1). As shown in FIG. 4A, the position of scissors (A) is within the periphery (32).
