The body includes a member proximate the second face for coupling the accessory to the shoe. A guiding surface is defined on the first face of the body for engaging a workpiece and an opening is formed in the body for receiving the blade. The guiding surface constitutes a modified surface configured to differ from the guiding surface of the shoe by at least one characteristic. ## Claims ### Claim 1 A power tool comprising: a main body including a motor configured to transfer motion to a cutting blade; a shoe extending from the main body, the shoe comprising, a first guiding surface for engaging a workpiece, a rear shoe surface generally opposite the first guiding surface, transverse shoe walls extending from the rear shoe surface, the transverse shoe walls having shoe ends, and an opening through which the cutting blade passes; and a shoe accessory comprising, a rear accessory surface facing the first guiding surface of the shoe, transverse accessory walls extending from the rear accessory surface, wherein at least one member extends from at least one of the transverse walls and over at least a portion of at least one of the shoe ends such that the shoe is received in a receptacle defined between the at least one member, the rear accessory surface, and the transverse accessory walls in a snap fitting manner such that at least a portion of the shoe ends are exposed, and a second guiding surface opposite the rear surface and for engaging the workpiece, the second guiding surface having at least one characteristic that differs from the first guiding surface. ### Claim 2 (depends on 1) The power tool of claim 1, wherein when the shoe accessory is coupled to the shoe, the first guiding surface is covered such that during operation of the power tool the second guiding surface engages the workpiece. ### Claim 3 (depends on 1) The power tool of claim 1, wherein the at least one characteristic includes a plurality of teeth arranged substantially in a row. ### Claim 4 (depends on 1) The power tool of claim 1, further comprising a grip extension extending from at least one of the transverse accessory walls. ### Claim 5 (depends on 4) The power tool of claim 4, wherein the grip extension extends away from the at least one transverse accessory wall in a direction generally opposite the at least one member. ### Claim 6 (depends on 1) The power tool of claim 1, wherein the at least one member includes a plurality of discrete projections extending from the transverse accessory walls, wherein the plurality of discrete projections cover at least portions of the shoe ends allowing the shoe accessory to be snap-fitted to the shoe. ### Claim 7 (depends on 1) The power tool of claim 1, wherein the receptacle is substantially cuboid-shaped. ### Claim 8 (depends on 1) The power tool of claim 1, wherein the at least one characteristic includes a first curved wall extending from one of the transverse accessory walls and a second curved wall extending from a second of the transverse accessory walls, the curved walls are adjacent to the second guiding surface and extend beyond a boundary of the second guiding surface allowing the curved walls to act as a pivot for the power tool. ### Claim 9 (depends on 1) The power tool of claim 1, wherein the at least one characteristic includes a pair of opposed projections extending from the second guiding surface of the shoe accessory, one of the projections positioned proximate a top edge of the shoe accessory, the other projection positioned proximate a bottom edge of the shoe accessory, and each of the projections including an inclined surface intersecting the second guiding surface, the inclined surface of one projection facing the inclined surface of the other projection, and further wherein the projections define an inclined portion of the second guiding surface of the shoe accessory for locating a workpiece having a curved surface with respect to the accessory. ### Claim 10 A power tool comprising: a main body including a motor configured to transfer motion to a cutting blade; a shoe extending from the main body, the shoe comprising, a first guiding surface for engaging a workpiece, a rear shoe surface generally opposite the first guiding surface, transverse shoe walls extending from the rear shoe surface, the transverse shoe walls having shoe ends, and a first opening through which the cutting blade passes; and a shoe accessory comprising, a rear accessory surface facing the first guiding surface of the shoe, a second guiding surface opposite the rear surface and for engaging the workpiece, the second guiding surface having at least one characteristic that differs from the first guiding surface, a second opening through which the cutting blade passes, the second opening configured to align with the first opening when the shoe accessory is coupled to the shoe, and transverse accessory walls extending from the rear accessory surface, wherein at least one projection extends from at least one of the transverse accessory walls and covers at least a portion of at least one of the shoe ends such that the shoe is received in a receptacle defined between the at least one projection, the rear accessory surface, and the transverse accessory walls in a snap fitting manner where at least a portion of the shoe ends are exposed. ### Claim 11 (depends on 10) The power tool of claim 10, wherein the rear surface covers the first guiding surface when the shoe accessory is coupled to the shoe such that in operation the second guiding surface engages the workpiece. ### Claim 12 (depends on 10) The power tool of claim 10, wherein the at least one characteristic is a plurality of teeth arranged substantially in a row. ### Claim 13 (depends on 12) The power tool of claim 12, wherein the plurality of teeth are positioned proximate a portion of the second opening. ### Claim 14 (depends on 10) The power tool of claim 10, further comprising a grip extension extending from at least one of the transverse accessory walls. ### Claim 15 (depends on 14) The power tool of claim 14, wherein the grip extension extends away from the at least one transverse accessory wall in a direction generally opposite the at least one projection. ### Claim 16 (depends on 10) The power tool of claim 10, wherein the at least one characteristic includes a first curved wall extending from one of the transverse accessory walls and a second curved wall extending from a second of the transverse accessory walls, the curved walls are adjacent to the second guiding surface and extend beyond a boundary of the second guiding surface allowing the curved walls to act as a pivot for the power tool. ### Claim 17 (depends on 10) The power tool of claim 10, wherein the at least one projection includes a plurality of discrete projections extending from the transverse accessory walls, wherein the plurality of discrete projections cover at least portions of the shoe ends allowing the shoe accessory to be snap-fitted to the shoe. ### Claim 18 (depends on 10) The power tool of claim 10, wherein the receptacle is substantially cuboid-shaped. ### Claim 19 (depends on 10) The power tool of claim 10, wherein the at least one characteristic includes a pair of opposed projections extending from the second guiding surface of the shoe accessory, one of the projections positioned proximate a top edge of the shoe accessory, the other projection positioned proximate a bottom edge of the shoe accessory, and each of the projections including an inclined surface intersecting the second guiding surface, the inclined surface of one projection facing the inclined surface of the other projection, and further wherein the projections define an inclined portion of the second guiding surface of the shoe accessory for locating a workpiece having a curved surface with respect to the accessory.
