In certain embodiments the first distance 1235 and the second distance 1245 are equal, however embodiments of the present invention are not restricted thereto. The second aperture 1240 is configured such that when the second end 1220 of the blade is inserted within the handle 1100 in a second configuration 2020, the second aperture 1240 of the blade aligns with the aperture 1600 of the first side, and thereby the locator pin 1700. Thereby the first cutting edge 1215 is exposed for use in the second configuration. While embodiments of a blade 1200 comprising two edges shown herein comprise two apertures, embodiments wherein a single aperture through the blade is configured to align with the aperture 1600 of the first side in a first configuration 2010 or second configuration 2020 are within the spirit and scope of the present invention. Furthermore, while embodiments shown comprise apertures through the thickness of the blade, notches through the thickness of the blade which are coincident with a longitudinal edge of the blade are within the spirit and scope of the present invention.
[0038] Although embodiments show apertures of the blade comprising a thru-hole, for the purposes of the present application, an “aperture”, in addition to its ordinary and customary meaning, includes a notch in a perimetral edge of the blade.
[0039] In certain embodiments, as shown in FIG. 1-FIG. 6B for instance, a locator pin 1700 is configured to interconnect between at least a first side 1110 of the handle and through an aperture (1230, 1240) of the blade wherein when the locator pin 1600 is interconnected with the handle system 1000 the blade 1200 is constrained from being removed in a longitudinal direction from the handle system. The locator pin 1700 is interconnected with the handle system 1000 when the locator pin is inserted through an aperture 1600 through the first side, and though an aperture (1230, 1240) of the blade. When the locator pin 1700 is removed, the blade 1200 is unconstrained and the blade 1200 can be removed in a longitudinal direction. While certain embodiments shown herein illustrate the locator pin 1700 as a removable element, in certain embodiments the locator pin 1700 is permanently interconnected with the first side 1110 of the handle. In certain embodiments, the locator pin 1700 is affixed to the first side 1110 of the handle, wherein assembly of the first side 1110 with the second side 1120 with the locator pin 1700 aligned with an aperture (1230, 1240) of the blade serves to constrain the blade 1200 within the handle 1000, and wherein separating the first side 1110 from the second side 1120 results in the blade 1200 being unconstrained in relation to the handle system 1000.
[0040] In certain embodiments, a second side 1120 of the handle system comprises a recess 1800 on an internal aspect 1125 of the second side wherein the locator pin 1700 is configured to be inserted through an aperture 1600 in the first side, through an aperture (1230,1240) of the blade, and into the recess 1800 on an internal aspect 1125 of the second side. Embodiments wherein the recess 1800 comprises a thru-hole, and embodiments wherein the locator pin 1700 extends through the first side 1110 and the second side 1120 are within the spirit and scope of the present invention.
[0041] In certain embodiments, shown in FIG. 6A-FIG. 6B for example, a blade 1200 comprises a first end 1210 having a first edge 1215 and a second end 1220 having a second edge 1225. The first edge 1215 and the second edge 1225 can be configured similarly or in differently. The edge type configurations that may be used include, but are not limited to, a straight edge scraper, a curved edge scraper, a swept edge scraper, a skewed edge scraper, parting tools.
[0042] In certain embodiments of the present invention, a handle system 1000 comprises a handle 1100 comprising a vibration damping material. In certain embodiments, as shown in FIG. 1-FIG. 8B for example, the handle 1100 comprises a vibration damping material such as urethane polymer comprising mechanical qualities of a 55 D-75 D durometer. A non-ferromagnetic material provides advantages to isolate the magnetism of the magnets 1400 from affecting the 1200 blade which is commonly made of a steel alloy. Without isolating the blade 1200 from the magnets 1400, the material of the blade 1200 may become magnetized which affects the usability of the blade 1200 as a magnetized blade may not glide freely across a tool rest as necessary for use with a lathe. Handles comprising alternative materials such as rubbers, polyurethanes, urethanes outside of the indicated durometer range, or other polymeric compounds are within the spirit and scope of the present invention. Furthermore, the use of a vibration damping material as a first side 1110 of the handle, the second side 1120 of the handle, the first side 1110 and second side 1120 of the handle, or between the sides of the handle 1100 and the blade 1200—are within the spirit and scope of the present invention.
[0043] In certain embodiments as shown in FIG. 7A-FIG. 7C, a handle system 1000 comprises a handle 1100 further comprising a measuring device 2000 interconnected thereto. In certain embodiments, the measuring device 2000 is displayed longitudinally along an external surface 1160 of the handle. As shown in FIG. 7A—FIG. 7C, certain embodiments comprise a first measuring device 2000 in a first measuring scale (such as metric units), and a second measuring device 2000′ in a second measuring scale (such as imperial units). The measuring device 2000 as shown in FIG. 7, comprises embossed increments and numerical elements. However, alternative measuring devices 2000 comprising printed, painted, or raised increments and numerical elements are within the spirit and scope of the present invention. Furthermore, alternative embodiments wherein the measuring device 2000 comprises an extendable retractable measuring device which extends from the handle are within the spirit and scope of the present invention. In certain embodiments, as shown in FIG. 7B for example, a measuring device is aligned with a first longitudinal edge 1170 or a second longitudinal edge 1180 of the handle.
[0044] In certain embodiments of the present invention, such as shown in FIG. 7C of the present invention, a level indicator device 2100 is interconnected with the handle 1100. In certain embodiments as shown, the level indicator 2100 comprises a bulls-eye level. However, alternative level indicators such as a spirit level or inclinometer, are within the spirit and scope of the present invention.
[0045] In certain embodiments as shown in FIG. 1-FIG. 4B, and FIG. 6A-FIG. 6B, the handle 1100 comprises a faceted shape wherein the handle comprises a plurality of planar surfaces. Alternatively, in certain embodiments such as shown in FIG. 7A-FIG. 8B, the handle 1100 comprises a curvilinear surface. Furthermore, embodiments wherein the handle 1100 comprises a faceted surface in combination with a curvilinear surface are within the spirit and scope of the present invention. In certain embodiments, as shown in FIG. 7A, the handle comprises an oval shaped profile, while alternate embodiments having differing profiles are within the spirit and scope of the present invention.
[0046] In certain embodiments, as shown in FIG. 8A-FIG. 8B for instance, a first end 1010 of the handle comprises a finger recess 1900, and in certain embodiments a second end 1020 of the handle comprises a finger recess 1900. It may be desired for both the first end 1010 and the second end 1020 of the handle each to comprise a finger recess 1900. While embodiments as shown comprise the finger recess 1900 as interconnected with the second side 1120 of the handle, embodiments disclosed herein are not limited thereto. Furthermore, embodiments wherein the finger recess 1900 is located along a longitudinal edge (1170, 1180) of the handle are within the spirit and scope of the present invention. A finger recess 1900 is adapted to allow a user to place their finger therein to provide a better grip on the second side 1220 of the handle system to assist in separating the second side 1120 from the first side 1110, and thereby allow access to the blade 1200 within the handle system 1000 for operations such as removal, replacement, or reorienting the blade 1200.
[0047] While various embodiments of the present invention have been described in detail, it is apparent that modifications and alterations of those embodiments will occur to those skilled in the art. However, it is to be expressly understood that such modifications and alterations are within the scope and spirit of the present invention.
