## Background
FIELD OF THE TECHNOLOGY
The present application relates to a bendable and shape-retaining hair cutting apparatus.
BACKGROUND
Cutting of hair usually involves the use of a comb and a pair of scissors. A user needs to use both hands to cut hair. One hand is used to hold the comb and run it down a section of the hair. When a desired length is reached, the user anchors the hair between the index and middle fingers and snips the ends sticking out of the fingers. This snipping action has to be repeated many times until the ends are uniform. This haircutting process is time consuming. The ends of the hair may not be uniformly cut, and the fingers may be injured by the sharp blades of the scissors. Also, stylish haircuts are difficult to create because the comb and the blades of the scissors are straight and not bendable.
There is a need to produce a bendable and shape-retaining hair cutting apparatus for creating stylish haircuts of various shapes and cutting hair quickly in one push of a button.
The above description of the background is provided to aid in understanding a hair cutting apparatus, but is not admitted to describe or constitute pertinent prior art to the hair cutting apparatus, or consider the cited documents as material to the patentability of the claims of the present application.

As used herein, the term “bendable” means (a long object) capable of being turned or bent by force from a straight form into a curved or angular form, as well as from a curved or angular form into some other form or back into the straight form. Similarly, as used herein, the term “bend” means turning (a long object) by force from a straight form into a curved or angular form, as well as from a curved or angular form into some other form or back into the straight form. As used herein, the term “shape-retaining” means (a long object) being able to hold its shape when bent and does not bounce back to its original position. And, as used herein, the term “bendable and shape-retaining metal or alloy” means a metal or alloy having bendable and shape-retaining characteristics so that when a long object is made of such metal or alloy, the long object can be bent and held in the bent shape without bouncing back to its original position.
The bendable and shape-retaining hair cutting apparatus may include first and second resilient clip members 10, 12 disposed side-by-side and provided with oppositely facing first and second grooves 14, 16 formed on opposite inner sides 18, 20 of the first and second resilient clip members 10, 12 respectively. The first and second resilient clip members 10, 12 may be made of shape-retaining plastic that can retain their shapes when bent. The shape-retaining plastic may be polyethylene, polyurethane, polystyrene, or combinations thereof, or any other appropriate material.
A hinged end of the first clip member 10 may be hingedly connected with a hinged end of the second clip member 12 by a hinge 40, and an opposite free end of the first clip member 10 can be fastened to an opposite free end of the second clip member 12 by a fastener 50.
The bendable and shape-retaining hair cutting apparatus may include a first blade 22 and a second blade 24. The first blade 22 can be fixedly mounted in the first groove 14 by adhesive material, fasteners or any other suitable means. The second blade 24 can be moveably mounted in the second groove 16, and adapted to be inserted into the first groove 14 and driven into a slidable and shearing engagement with the first blade 18. The first and second blades 22, 24 may be made of bendable and shape-retaining metal or alloy such as copper, copper alloy, aluminum, aluminum alloy, or combinations thereof, or any other suitable metal or alloy. When the first and second blades 22, 24 are made of bendable and shape-retaining metal such as copper, the first and second blades 22, 24 can be bent in an upward or downward direction from a plane on which the first and second blades 22, 24 lie into a desired shape, and retained into the desired shape. Both or one of the first and second blades 22, 24 may have a sharpened cutting edge.
At least one push plate 26 may extend transversely from an inner lateral side 28 of the second blade 24 and through a transverse bore 30 formed on an outer side 32 of the second clip member 24.

In the illustrated embodiment, the second blade 24 may be in the form of a toothed blade formed with a plurality of teeth 60 adapted to be inserted into the first groove 14 and slidably engaged with the first blade 14 when the first and second clip members 10, 12 are clipped together.
The method for creating stylish haircuts of various shapes and cutting hair in one push of a button using the bendable and shape-retaining hair cutting apparatus of the present application is shown in FIGS. 6(a) to 6(f).
To cut hair, a user first holds or fastens the first and second clip members 10, 12 side-by-side together, as shown in FIG. 6(a).
The user then bends the first and second clip members 10, 12 together with the first and second blades 22, 24 provided therein into a desired shape, as shown in FIG. 6(b). In this example, the desired shape is an upwardly curved shape.
The user then flips out the second clip member 12 and positions hair to be cut between the first and second clip members 10, 12, as shown in FIG. 6(c).
The second clip member 12 is then flipped back to the side-by-side closed position thereby clipping the hair to be cut between the first and second clip members 10, 12, as shown in FIG. 6(d).
Finally, the user pushes the push button 36 once so that the second blade 24 is moved laterally towards the first blade 22 and entered into slidable and shearing engagement therewith, thereby cutting hair clipped between the first and second clip members, as shown in FIG. 6(e).
An upwardly curved haircut is then created, as shown in FIG. 6(f).
FIG. 7(a)-7(j) show the creation of haircuts of various shapes using the bendable and shape-retaining hair cutting apparatus of the present application. FIG. 7(a) shows a “straight cut” of the hair at the back a head. FIG. 7(b) shows a “straight bangs cut” of the hair above the forehead.
