A distance between the edge radius and the tooth radius at any point along the working edge is the same. ## Claims ### Claim 1 A trowel comprising: at least one working edge; and a plurality of radial teeth extending from said working edge, each radial tooth of said plurality of radial teeth comprising a radial edge, wherein a straight-line distance extending radially outward from said working edge to said radial edge of at least one radial tooth of said plurality of radial teeth varies along said radial edge of said at least one radial tooth. ### Claim 2 (depends on 1) The trowel of claim 1 wherein each radial tooth of said plurality of radial teeth are rotatably coupled to said working edge. ### Claim 3 (depends on 1) The trowel of claim 1 wherein said radial edge extends circumferentially about said radial tooth. ### Claim 4 (depends on 1) The trowel of claim 1 wherein said radial edge comprises a constant curve. ### Claim 5 (depends on 1) The trowel of claim 1 wherein said radial edge comprises at least two flat surfaces that intersect. ### Claim 6 (depends on 1) The trowel of claim 1 wherein each radial tooth of said plurality of radial teeth comprises a circular cross-sectional shape. ### Claim 7 (depends on 1) The trowel of claim 1 wherein said working edge is straight. ### Claim 8 (depends on 1) The trowel of claim 1 wherein said working edge is contoured. ### Claim 9 (depends on 1) The trowel of claim 1 further comprising: a second working edge; and a second plurality of radial teeth extending from said second working edge. ### Claim 10 (depends on 9) The trowel of claim 9 wherein said working edge is straight and said second working edge is contoured. ### Claim 11 (depends on 9) The trowel of claim 9 wherein each radial tooth of said plurality of radial teeth comprises a first size and a first shape; and wherein each radial tooth of said second plurality of radial teeth comprises a second size and a second shape. ### Claim 12 (depends on 11) The trowel of claim 11 wherein at least one of said first size and said first shape is different from at least one of said second size and said second shape. ### Claim 13 A trowel comprising: a main body comprising at least one working edge, said working edge comprising an edge radial center and an edge radius; and a plurality of radial teeth extending from said working edge, each radial tooth of said plurality of radial teeth comprising a radial edge, a tooth radial center and a tooth radius, wherein said tooth radial center of at least one radial tooth of said plurality of radial teeth is offset from said edge radial center of said working edge, and wherein a straight-line distance extending radially outward from said edge radial center of said working edge of said main body to said radial edge of said at least one radial tooth of said plurality of radial teeth varies along said radial edge of said at least one radial tooth. ### Claim 14 (depends on 13) The trowel of claim 13 wherein said plurality of radial teeth are spaced apart and aligned along said working edge. ### Claim 15 (depends on 13) The trowel of claim 13 wherein each radial tooth of said plurality of radial teeth comprises a tooth body, said tooth body comprising a first thickness; and wherein said radial edge extends circumferentially about said tooth body, said radial edge comprising a second thickness. ### Claim 16 (depends on 15) The trowel of claim 15 wherein said tooth body is disk-shape. ### Claim 17 (depends on 15) The trowel of claim 15 wherein said tooth body is spherical. ### Claim 18 (depends on 15) The trowel of claim 15 wherein said first thickness is substantially equal to said second thickness. ### Claim 19 (depends on 15) The trowel of claim 15 wherein said first thickness is different than said second thickness. ### Claim 20 (depends on 13) The trowel of claim 13 wherein said main body comprises at least one second working edge and a second plurality of radial teeth extending from said second working edge, each radial tooth of said second plurality of radial teeth comprising a radial edge and a second tooth radius, wherein said tooth radius and said second tooth radius are different. ### Claim 21 (depends on 20) The trowel of claim 20 wherein: each radial tooth of said plurality of radial teeth comprises a first shape and a first size; each radial tooth of said second plurality of radial teeth comprises a second shape and a second size; and at least one of said first shape and said first size is different from at least one of said second shape and said second size.
