Those skilled in the art will understand that the methods, systems, and devices specifically described herein and illustrated in the accompanying drawings are non-limiting examples and that the scope of the present disclosure is defined solely by the claims. The features illustrated or described in connection with one example may be combined with the features of other examples. Such modifications and variations are intended to be included within the scope of the present disclosure.

[0034] The terms “significantly”, “substantially”, “approximately”, “about”, “relatively,” or other such similar terms that may be used throughout this disclosure, including the claims, are used to describe and account for small fluctuations, such as due to variations in processing from a reference or parameter. Such small fluctuations include a zero fluctuation from the reference or parameter as well. For example, they can refer to less than or equal to ±10%, such as less than or equal to ±5%, such as less than or equal to ±2%, such as less than or equal to ±1%, such as less than or equal to ±0.5%, such as less than or equal to ±0.2%, such as less than or equal to ±0.1%, such as less than or equal to ±0.05%.

[0035] Referring to FIGS. 1A, 2A, and 3A an example is depicted of a side perspective view (FIG. 1A), a side-rear perspective view (FIG. 2A) and a top view (FIG. 3A) of a multi-blade knife assembly 100. The example of the multi-blade knife assembly 100 as illustrated in FIGS. 1A-3A includes 3 blades 102. The multi-blade knife assembly 100 of FIGS. 1A-3A also includes a protective cover 104 press fit thereon, according to aspects described herein.

[0036] Referring also to FIGS. 1B, 2B, and 3B another example is depicted of a side perspective view (FIG. 1B), a side-rear perspective view (FIG. 2B) and a top view (FIG. 3B) of a multi-blade knife assembly 100. The example of the multi-blade knife assembly 100 as illustrated in FIGS. 1B-3B includes 2 blades 102. The multi-blade knife assembly 100 of FIGS. 1B-3B also includes a protective cover 104 press fit thereon, according to aspects described herein. 0037. The multi-blade knife assembly 100 includes a multi-bladed knife 106 and a protective cover 104. The multi-bladed knife 106 includes a handle 108 and a plurality of blades 102 attached to the handle 108. Each blade 102 of the plurality of blades 102 extends longitudinally from the handle 108 and also extends substantially parallel to each other. Each blade 102 includes a bottom cutting edge 110 and a top non-cutting edge 112 connected therebetween by opposing blade side surfaces 114.

[0037] Though the multi-blade knife assemblies 100 of FIGS. 1A-3A and FIGS. 1B-3B illustrate 3 bladed and 2 bladed knife assemblies 100 respectively, the knife assembly 100 may be designed to include any number of blades 102. For example, a multi-blade knife assembly 100 may include a pair of blades 102, three blades 102, four blades 102, five blades 102 or more.

[0038] The plurality of blades 102 may be permanently affixed to the handle 108 of the multi-bladed knife 106. However, in the examples illustrated in FIGS. 1A-3A and 1B-3B, each blade 102 of the plurality of blades 102 are removably attached to the handle 108 of the knife 106.

[0039] With regards to the blades 102 being removably attached, a blade connector mechanism 126 is positioned between the handle 108 and the plurality of blades 102. The blade connector mechanism 126 is operable to attach and detach each blade 102 of the plurality of blades 102 to the handle 108 of the knife 106. The blade connector mechanism may operate via any number of appropriate attachment features. For example, and without limitation, a spring loaded disconnect button 128 may be depressed to leverage and disconnect a latching retainer (not shown) from a base portion (not shown) of the detachable blade 102 that is inserted into the front end of the handle 108.

[0040] The protective cover 104 includes a cover top 116 and a pair of opposing cover side walls 118. The cover top 116 is configured to fit over a substantial portion of each of the top non-cutting edges 112 of the plurality of blades 102. The cover side walls 118 extend downward and substantially parallel to each other from opposing end portions 120 of the cover top 116. The cover side walls 118 are spaced a predetermined distance 122 apart to frictionally fit against outer most side surfaces 114A of opposing outer most blades 102 of the plurality of blades 102.

[0041] Though the cover side walls 118 are each illustrated in FIGS. 1A-3A and 1B-3B as a single side wall 118 extending substantially entirely across the distal side ends 124 of the top 116 of the protective cover 104, the cover side walls 118 may be designed in several other configurations. For example, the cover side walls 118 may be configured as multiple tab-like sections extending across each distal side end 124 of the cover top 116. Moreover, the end portion 120, from which the side walls 118 extend, may include more than just the distal side ends 124 of the cover top 116. Rather the end portions 120 may include an outer quarter or an outer third of the cover top 116 and the side walls 118 may extend from any position within the boundaries of the end portions 120.

[0042] The protective cover 104 includes a finger ring 130 pivotally attached to the cover top 116. The finger ring 130 is sized to receive a finger 132 of a user's hand 134 therethrough. The protective cover 104 is operable to protect and cushion a user's hand 134 when pressing on the non-cutting edges 112 of the plurality of blades 102 during a chopping operation (see FIG. 6). The finger ring 130 is operable to anchor the user's finger 132 to the cover 104 such that the user's hand 134 does not inadvertently slide off of the plurality of blades 102 during the chopping operation.

[0043] The protective cover 104 may be permanently affixed to the blades 102 of the multi-bladed knife 106. However, in the examples illustrated in FIGS. 1A-3A and 1B-3B, the protective cover 104 is removably frictionally fit over the plurality of blades 102.

[0044] Referring to FIGS. 4A and 4B, an example is depicted of a front view (FIG. 4A) of the 3 bladed multi-blade knife assembly 100 of FIG. 1A and a front view (FIG. 4B) of the 2 bladed multi-blade knife assembly 100 of FIG. 1B, according to aspects described herein. The examples of a protective cover 104 illustrated in FIGS. 4A and 4B each include at least one spacer tab 136 extending downward and substantially parallel to the cover side walls 118 from the cover top 116. The at least one spacer tab 136 has a thickness 138 that is sized to frictionally fit into at least one separation space 140 formed between side surfaces 114 of a pair of adjacent blades 102 of the multi-bladed knife 106.

[0045] The at least one spacer tab 136 may include a plurality of spacer tabs 136, wherein each spacer tab 136 is sized to frictionally fit into each separation space 140 formed between side surfaces 114 of each pair of adjacent blades 102 of the knife 106. In the specific example illustrated in FIG. 4B, the at least one spacer tab 136 includes a single spacer tab 136 sized to frictionally fit between a single pair of blades 102 of the knife 106. In the specific example illustrated in FIG. 4A, the at least one spacer tab 136 includes a first spacer tab 136A and a second spacer tab 136B. The first spacer tab 136A is sized to frictionally fit between a first separation space 140A formed between side surfaces 114 of a first blade 102A adjacent to a second blade 102B of the multi-bladed knife 106. The second spacer tab 136B sized to frictionally fit between a second space 140B formed between side surfaces 114 of the second blade 102B adjacent to a third blade 102C of the multi-bladed knife 106.

[0046] The spacer tabs 136 help keep the blades 102 of the knife 106 aligned and separated. Additionally, the spacer tabs 136 help to frictionally fit the protective cover 104 to the blades 102 such that the protective cover 104 will not inadvertently slip along the non-cutting edges 112 of the blades 102 during a cutting operation.

[0047] Referring to FIG. 5, an example is depicted of a perspective view of a protective cover 104 for a 3 bladed multi-blade knife assembly 100, according to aspects described herein. As described earlier herein, the protective cover 104 is removable from the blades 102 of the knife 106. The protective cover 104 includes the cover top 116. Extending downward from end portions 120 of the cover top 116 are an opposing pair of side walls 118. Extending between the side walls are the first spacer tab 136A and second spacer tab 136B. There can be any number of spacer tabs 136 to frictionally fit between any number of separations spaces 140 formed by any number of pairs of adjacent blades 102 of the multi-bladed knife assembly 100.

[0048] Referring to FIG. 6, an example is depicted of a view of a 3 bladed multi-blade knife assembly 100 being handled by a user during a chopping operation, according to aspects described herein. The user will grasp the handle 108 with one hand 142 and anchor his other hand 134 to the protective cover 104 by slipping a finger 132 through the finger ring 130 attached to the protective cover 104.

[0049] The multiple blades 102 may make multiple cuts simultaneously into an object for speed and efficiency. In the example illustrated in FIG. 6, the 3 blades 102 of the knife assembly 100 are simultaneously making three cuts into a carrot 144. However, any number of other items may be used with the knife assembly 100. For example, and without limitation, other vegetables, fruits, nuts or various other food items.

[0050] Advantageously, the protective cover 104 over the non-cutting edges 112 of the knife blades 102 provides protection and cushioning of the user's hand 134 during the cutting or chopping operation. Moreover, the finger ring 130 disposed on the protective cover 104 functions to anchor the user's finger 132 to the cover 104 such that the user's hand 134 does not inadvertently slide off of the plurality of blades 102 during the chopping operation.
