DETAILED DESCRIPTION

[0030] Some known lames may have a double edged "safety razor" blade affixed to a relatively long, thin metal pole extending from a handle. The blades may have holes along a center line of the blade. The blades may be flexible so that they can be bent between thumb and forefinger in such a way that the thin pole can be slid through it where the blade then stays in place.

[0031] Such lames may suffer from various problems. For example, it may be dangerous to attach the blade; the blade is spring loaded when flexed, and it can become an

unpredictable projectile if a finger slips when installing or removing the blade. Further, Slicing bread may require only about a quarter inch of one blade corner. Known lames may leave four corners of the blade exposed at all times, which is three more than necessary. More blade exposure means a higher risk of injury or unintended damage. More blade exposure also means there is more opportunity for unused blade corners and edges to wear and dull before use (for example by placing the tool in a drawer and it rubs against other utensils, etc.).

[0032] Further, by having the bottom back blade edge exposed in such lames, the lame may be prone to "catching", whereby when the user makes a slicing motion from front to back, the back blade will catch the dough and drag, creating an undesirable effect. Another disadvantage is that the blade in such known lames may be very loosely attached to the pole, making it easy to dislodge and come off when slicing, or to lose a proper orientation or profile. Another disadvantage is that such lames may only allow for a curved, flexible blade. There are some patterns and bread types for which a straight blade is preferred (as well as some for which a curved blade is preferred).

[0033] Another known type of lame is a straight lame, which still requires handling of the blade in a dangerous manner, and may rely on some sort of vice, clamp, or clasp mechanism to hold the blade in place. Blades for straight lames can only be straight. These lames only offer a straight blade option (i.e., no curved blade option). [0034] Some have tried to solve aforementioned problems by implementing a living hinge that: (1) closes onto a safety razor; (2) presses it into a curve shape; and (3) snaps in place. Another attempted solution is to snap the blade in place using the cutout detail located in the center of a blade. A male plastic part may fill this void and a female connector may snap it into place. Within the flexible plastic components is a thin piece of metal that can be bent in to a curve shape by the user. The blade fits into place, and can then be manipulated after the fact to be curved or straight. The plastic may be thin enough to move, and inside is a bendable piece of metal, which can bend and then keeps the entire arm in that shape. In such lames, while the clasp or snap hinge mechanisms may secure the blade in place, these mechanisms may still require the user to handle the blade on the sharp edges to align the grooves and then snap the blade into place. Also, with these mechanisms, the top and bottom edges of the blade remain exposed after it is secured. In some cases, back edge of the blade may "catch" on the dough creating unwanted tears rather than clean score lines.

[0035] Another known solution is to permanently fix the blade to the lame. However, such a blade may need to be customized and may not accommodate a standard safety razor blade. Furthermore, the blade may become dull after some time, forcing the user to sharpen the blade rather than using a different leading edge or replacing the blade entirely. Again, the back edge may be exposed which can cause the lame to catch on the dough.

[0036] Another known solution is a slot and clamp mechanism that has been used in some lame tools in order to place the blade into position and tighten it down with some freedom when positioning the blade. While placing the blade into a slot and clamping the blade down may allow the user to control the exposure of the blade, this device may only accommodate straight blade profiles, and not curved blade profiles. Furthermore, the user may be required to handle the blade on the sharp bottom edge to slide the top edge in to the handle and secure it in place; such handling of the blade can be unsafe.

[0037] The present disclosure overcomes these problems and provides a solution in which the back edge of the lame may not catch on the dough, given that it may only expose one leading edge of the blade. This may be achieved by covering three of the four corners of the blade, rather than the blade being exposed on the top and bottom as in known lames. In addition, only having a certain amount of blade exposed in the blade holder may be safer for the user as it may prevent a user' s hand from sliding off the handle and on to the top of the blade.

[0038] Further, the present disclosure provides a solution that may incorporate two removable heads (e.g. , blade holders); one on each end of the handle. One blade holder may be for a straight blade application, the other for a curved blade application. By incorporating two removable blade holders, the disclosed lame design can achieve both a curved and straight blade profiles as needed for various scoring techniques. Further, the razor blade may be inserted from the back of the blade holder, and then locked into place when the blade holder slides in to the handle. Sliding the blade in from the back of the blade holder prevents the user from handling the sharp edges of the blade and ensures the assembly process is safe. This solution avoids snapping material around the razor blade via a clasp, or tightening the razor blade in place. Once the razor blade is inserted in to the blade holder and then assembled to the handle the razor blade is locked in and may not readily separate from the tool.

[0039] The disclosed lame may accommodate readily available double-sided safety razor blades that are commonly available and inexpensive. Further, the razor blade may not be permanently fixed. Given that only one leading edge is exposed, the razor blade can also be rotated around (e.g. , manually) when one side becomes dull, thus increasing the longevity of the razor blade. An additional feature is a cover that safely covers the exposed razor blade for storage. This also prevents the blade from becoming dull. The finger loop is a feature that allows the cover to be easily removed and doubles as a hook for a storage solution.

[0040] FIGS, la and lb illustrate an exemplary lame 100 in accordance with aspects of this disclosure. The lame 100 has a central portion 102 (which may serve as a handle) which can securely mate with removable blade holders 104 or 106 at either end of the central portion 102. Each removable blade holder 104 and 106 is configured to securely hold a razor blade (108 and 110 respectively). Each razor blade 108 or 110 may have four corners, and the blade holders 104 or 106 may shield three of the four corners within the perimeters of the blade holders 104 or 106. When only one leading edge of the razor blade(s) 108 or 110 is exposed, safety hazards may be reduced, and the back edge of the razor blade may not catch on the dough, as is a problem in other known lames. In some embodiments, the handle 102 may only mate with one blade holder 104 or 106. [0041] Removable blade holders 104 or 106 may hold a razor blade in either a curved or a straight profile. Because the blade holders 104 or 106 are non-destructively removable from the handle 102, different blade profiles (curved or straight) may be applied to the handle. For example, as shown in FIG. lb, blade holder 104 holds razor blade 108 in a straight profile, and blade holder 106 holds razor blade 110 in a curved profile. Each blade holder 104 or 106 may be assembled on either side of the handle 102 (e.g. , modular). In some examples, both blade holders 104 or 106 may hold both razor blades 108 or 110 in a straight profile. In some examples, both blade holders 104 orl06 may hold both razor blades 108 or 110 in a curved profile.

[0042] As will be described in more detail with reference to FIGS. 2a-4, the blade holder(s) 104 or 106 may be configured to engage with and disengage from the handle 102. For example, the blade holder(s) 104 or 106 may have mating portions that may engage with and disengage from corresponding mating portions of the handle 102. For example, the mating portion of blade holder(s) 104 or 106 may include one or more tongue(s) which may slide into and out of a corresponding slot in the mating portion of the handle 102 (or vice versa). Further, the blade holder(s) 104 or 106 may snap in to place (after the tongue(s) are inserted into the corresponding slots), in order to secure the blade holder(s) 104 or 106 to the handle 102, using a snap (e.g. , domed snap) feature in which a given blade holder (104 or 106) includes a male protrusion and the handle has a corresponding female recess (or vice versa). The blade holder(s) 104 or 106 may also non-destructively unsnap from the handle 102 and then slide out in order to disengage from the handle 102.

[0043] As will be described in more detail with reference to FIG. 5, the lame 100 may be configured to engage with a cover 502 to cover the exposed edge(s) of the razor blade(s) 108 or 110. The blade holder(s) 104 or 106 may have a protrusion 112 to engage with a corresponding recess or aperture 504 on the cover 502. The protrusion 112 may also be used to grip the blade holder(s) 104 or 106 when engaging or disengaging the blade holder(s) 104 or 106 from the handle 102.

[0044] The blade holder(s) 104 or 106, and the handle 102 may also include indicators 114 that may be may be used to indicate that the blade holder has been attached correctly to the handle 102. One side of the handle 102 may have two markings (e.g. , dots), the other side may have one marking. One side of the blade holder(s) 104 and 106 may have two markings, and the other side may have one marking. For example, FIG. la shows a first side of the handle 102 and blade holders 104 and 106 with two markings 114 (dots), and FIG. lb shows the other side of the handle 102 and blade holders 104 and 106 with two markings 114 (dots). A user may align the sides with corresponding dots to ensure the blade holder(s) 104 and 106 is attached correctly to the handle 102.

[0045] FIGS. 2a and 2b illustrate an exploded view of an exemplary lame 100. In the exemplary lame 100 of FIGS. 2a and 2b, each blade holder 104 or 106 opens into two portions. For example, straight blade holder 104 may include a first portion 202 and a second portion 204, which when secured together; hold a razor blade 108 in a straight profile. In some examples, the first portion 202 and the second portion 204 may be completely separable, while in some examples, the first portion 202 and the second portion 204 may be connected by a hinge (e.g. , a living hinge) or other connecting portions.

[0046] As shown in FIGS. 2a and 2b, curved blade holder 106 may include a first portion 206 and a second portion 208, which when secured together, hold a razor blade 110 in a curved profile. In some examples, the first portion 206 and the second portion 208 may be completely separable, while in some examples, the first portion 206 and the second portion 208 may be connected by a hinge (e.g. , a living hinge) or other connecting portions. Each blade holder 104 or 106 may include one or more rails 210 which may guide the razor blades into the proper position. The one or more rails 210 may also hold the razor blades in the proper position.

[0047] As shown in FIGS. 2a and 2b, the blade holders 104 or 106 may have tongue(s) 212 that may slide into a corresponding slot 214 in the handle 102 in order to mate the blade holders 104 and 106 with the handle 102. Other slot and tongue features, or other mating arrangements, may also be used to mate the blade holders 104 or 106 to the handle 102. Further, the blade holders 104 or 106 may snap in to place (after the tongue(s) 212 are inserted into the slots 214) using a snap 216 (e.g. , domed snap) feature in which a given blade holder (104 and 106) includes a male protrusion 216 and the handle has a

corresponding female recess 218 (or vice versa). The protrusion may have a dome shape and the recess may have a complementary inverted dome shape. Once the blade holder(s) 104 or 106 are snapped in to place, the blade holder(s) 104 and 106 may not readily separate from the handle 102, as may be a problem in some known lames. [0048] As shown in FIGS. 2a and 2b, the blade holder(s) 104 or 106, and the handle 102 may also include indicators 114 that may be may be used to indicate that the blade holder has been attached correctly to the handle 102. One side of the handle 102 may have two markings, the other side may have one marking. One side of the blade holder(s) 104 and 106 may have two markings, and the other side may have one marking. A user may align the sides with corresponding markings to ensure the blade holder(s) 104 or 106 is attached correctly to the handle 102.

[0049] In some examples the blade holders 104 or 106 may be permanently secured together, or may be formed of one piece. FIG. 3 shows such an example for a curved blade holder 106. In such examples, the blade holder 106 may include a blade-receiving slot 302. A flexible razor blade 110 may be inserted by a user into the slot 302. Rails inside the blade holder may guide the razor blade 110 into position. The flexible razor blade 110 becomes curved due to the contour in the blade holder 106. A user may also withdraw the razor blade 110 from the blade holder 106.

[0050] A straight blade holder 104 may also be permanently secured together, or may be formed of one piece, as is the exemplary curved blade holder 106 of FIG. 3. Such a straight blade holder 104 may also have a slot for receiving and withdrawing a razor blade (not shown). Such a slot system for receiving and withdrawing a razor blade may be

advantageous because user has less interaction with the razor blade when

inserting/withdrawing the razor blade, whereas in other known lames the user may need to grip the razor blade on the sharp edges and bend the razor blade itself for a curved blade implementation

[0051] FIG. 4 illustrates an exploded view of an exemplary lame 100 with blade holders 104 and 106 that are permanently secured together, or formed of one piece. Each blade holder 104 or 106 may include a slot for receiving and withdrawing a respective razor blade 108 or 110.

[0052] FIG. 5 illustrates an exemplary cover 502 engaging with an exemplary lame 100. The cover may be useable to cover the straight blade holder 104 and/or the curved blade holder 106. The system may include two covers - one for each blade holder 104 and 106. The cover 502 may include apertures or recesses 504 (on one or both sides— top and bottom) that snap over corresponding protrusions 112 on the blade holder(s) 104 or 106. The cover 502 may include an aperture 506 for hanging on a hook and/or sized to receive a finger for safe removal of the cover 502. The cover 502 may also include indicators 114 that may be may be used to indicate that the cover 502 has been attached correctly to the blade holder(s) 104 or 106 and/or the handle 102. One side of the cover 502 may have two markings, the other side may have one marking. One side of the handle 102 may have two markings, the other side may have one marking. One side of the blade holder(s) 104 or 106 may have two marking, and the other side may have one marking. A user may align the sides with corresponding dots to ensure the cover 502 is attached correctly to the blade holder(s) 104 or 106 and/or the handle 102.

[0053] FIGS. 6a and 6b illustrate an exploded view of blade holders 104 or 106. FIG. 6a shows an exploded view of a straight blade holder 104. The straight blade holder 104 has a first portion 202 and a second portion 204. In some examples, the first portion 202 and the second portion 204 may be permanently secured together, or may be formed of one piece. In some examples, the first portion 202 and the second portion 204 may be completely non- destructively separable, while in some examples, the first portion 202 and the second portion 204 may be connected by a hinge or the like. The first portion 202 and the second portion 204 may have one or more guides 210 (e.g. , raised rails) which guide a razor blade into proper position when a razor blade is inserted into the blade holder 104. The guides 210 also secure the blade in the proper position.

[0054] FIG. 6b similarly shows an exploded view of a curved blade holder 106. The curved blade holder 104 has a first portion 206 and a second portion 208. The first portion 206 and the second portion 208 may be permanently secured together, or may be formed of one portion. In some examples, the first portion 206 and the second portion 208 may be completely non-destructively separable, while in some examples, the first portion 206 and the second portion 208 may be connected by a hinge or the like. The first portion 206 and the second portion 208 may have one or more guides 210 (e.g. , raised rails) which guide a razor blade into proper curved profile and position when a razor blade is inserted into the blade holder 106. The guide(s) 210 also secure the blade in the proper curved profile and position.

[0055] While the present apparatus and/or system has been described with reference to certain implementations, it will be understood by those skilled in the art that various changes may be made and equivalents may be substituted without departing from the scope of the present method and/or system. For example, block and/or components of disclosed examples may be combined, divided, re-arranged, and/or otherwise modified.
