The body includes a first portion, a tip portion, and a second portion extending from the first portion to the tip portion. The first portion has a height between about 0.625 inches and about 1.0 inches and the second portion has a height between about 0.18 inches and about 0.25 inches. The blade also includes a blunt tip formed at a distal end of the tip portion. An overall length of the blade is between about 2.4 inches and about 3.25 inches, measured from a proximal edge of the attachment portion to the blunt tip. The blade also includes a plurality of teeth arranged along the second portion and defining a cutting edge. ## Claims ### Claim 1 A blade for use with a reciprocating saw, the blade comprising: an attachment portion configured to couple to the reciprocating saw; a body extending from the attachment portion and including a first portion, a tip portion, and a second portion extending from the first portion to the tip portion, wherein the first portion has a height between about 0.625 inches and about 1.0 inches and the second portion has a height between about 0.18 inches and about 0.25 inches; a blunt tip formed at a distal end of the tip portion, wherein the blade includes an overall length between about 2.4 inches and about 3.25 inches, measured from a proximal edge of the attachment portion to the blunt tip; and a plurality of teeth arranged along the second portion; wherein the blade includes an axis in which it reciprocates in use, the plurality of teeth each having a flat cutting edge parallel to the axis. ### Claim 2 (depends on 1) The blade of claim 1, further comprising a transition portion of the body extending between the first portion and the second portion, the transition portion being sloped steeply between the height of the first portion and the height of the second portion. ### Claim 3 (depends on 1) The blade of claim 1, wherein the tip portion includes a tip height between about 0.062 inches and about 0.125 inches, measured substantially perpendicular to the cutting edge. ### Claim 4 (depends on 1) The blade of claim 1, wherein the plurality of teeth includes an upper tooth formed in an upper surface of the second portion and a lower tooth formed in a lower surface of the second portion. ### Claim 5 (depends on 4) The blade of claim 4, wherein the upper tooth and the lower tooth are substantially aligned in a direction substantially parallel to the axis. ### Claim 6 (depends on 4) The blade of claim 4, wherein the upper tooth and the lower tooth are offset from one another in a direction substantially parallel to the axis. ### Claim 7 (depends on 1) The blade of claim 1, wherein at least one of the plurality of teeth defines a first angle between about 45 degrees and about 85 degrees, measured between the flat cutting edge and a front edge of the at least one tooth, and wherein the at least one tooth defines a second angle between about 45 degrees and about 85 degrees, measured between the flat cutting edge and a rear edge of the at least one tooth. ### Claim 8 (depends on 1) The blade of claim 1, wherein the blunt tip includes a bevel defining a chisel feature. ### Claim 9 (depends on 1) The blade of claim 1, wherein the blade includes an overall length of about 2.5 inches, measured parallel to the axis from a proximal edge of the attachment portion to the blunt tip. ### Claim 10 (depends on 1) The blade of claim 1, wherein at least one of the plurality of teeth includes a tooth length between about 0.125 inches and about 0.325 inches. ### Claim 11 (depends on 10) The blade of claim 10, wherein the tooth length is about 0.2 inches. ### Claim 12 (depends on 10) The blade of claim 10, wherein the tooth length is about 0.26 inches. ### Claim 13 A blade for use with a reciprocating saw, the blade comprising: an attachment portion configured to couple to the reciprocating saw; a body extending from the attachment portion and including a first portion, a tip portion, and a second portion extending from the first portion to the tip portion, wherein the second portion has a height less than a height of the first portion; and the second portion having a plurality of gullets and a plurality of teeth, the teeth each having a flat cutting edge parallel to an axis in which the blade reciprocates in use, the gullets having a width of between about 0.125 inches and about 0.255 inches parallel to the axis and the teeth having a tooth length between about 0.125 inches and about 0.325 inches parallel to the axis. ### Claim 14 (depends on 13) The blade of claim 13, wherein the plurality of gullets includes an upper gullet formed in an upper surface of the second portion and a lower gullet formed in a lower surface of the second portion. ### Claim 15 (depends on 14) The blade of claim 14, wherein the upper gullet and the lower gullet are substantially aligned in a direction substantially parallel to the axis. ### Claim 16 (depends on 14) The blade of claim 14, wherein the upper gullet and the lower gullet are offset from one another in a direction substantially parallel to the axis. ### Claim 17 (depends on 13) The blade of claim 13, wherein at least one of the plurality of gullets includes two rounded corners, the two rounded corners including a radius between about 0.01 and about 0.04 inches. ### Claim 18 (depends on 13) The blade of claim 13, wherein at least one of the plurality of gullets includes a gullet depth between about 0.035 and about 0.080 inches. ### Claim 19 (depends on 13) The blade of claim 13, wherein the height of the first portion is between about 0.625 inches and about 1.0 inches, measured substantially perpendicular to the axis. ### Claim 20 (depends on 19) The blade of claim 19, wherein the height of the second portion is between about 0.18 inches and about 0.25 inches, measured substantially perpendicular to the axis. ### Claim 21 (depends on 20) The blade of claim 20, wherein the tip portion includes a tip height between about 0.062 inches and about 0.125 inches, measured substantially perpendicular to the axis. ### Claim 22 (depends on 20) The blade of claim 20, wherein the tip portion includes a tip height between about 0.18 inches and about 0.25 inches, measured substantially perpendicular to the axis. ### Claim 23 (depends on 13) The blade of claim 13, wherein the blade includes an overall length between about 2.4 inches and about 3.25 inches, measured substantially parallel to the axis from a proximal edge of the attachment portion to the blunt tip. ### Claim 24 (depends on 13) The blade of claim 13, wherein the first portion includes another flat cutting edge. ### Claim 25 (depends on 24) The blade of claim 24, wherein the first portion does not include a gullet.
