Recip blade
A recip blade has a blade body including a cutting edge and a tang located at one end of the blade body. The tang defines an arcuate cross-sectional shape or is laminated to increase the overall thickness of the tang and, in turn, enhance the rigidity of the blade and/or reduce oscillation or whipping of the blade during cutting.
1. A recip blade usable with a powered reciprocating saw, the recip blade comprising:
a substantially planar blade body comprising a cutting edge and extending along a blade axis;
a tang located at one end of the blade body and defining a cross-sectional shape that is curved continuously along at least a portion of a length of the tang and transverse to the blade axis across at least a portion of a width of the tang such that the tang is configured to be received in a blade holder of the powered reciprocating saw, the cross-sectional shape comprising:
a first arc-shaped portion having a first arcuate shape facing in a first direction; and
a second arc-shaped portion having a second arcuate shape continuous with the first arc-shaped portion and facing in a second direction opposite the first direction,
wherein the tang has an upper edge and a lower edge with the first-arc-shaped portion closer to the upper edge and the second arc-shaped portion closer to the lower edge.
2. The recip blade of claim 1 , wherein the first arcuate shape and the second arcuate shape are substantially the same.
3. The recip blade of claim 1 , wherein the cross-sectional shape is substantially s-shaped.
4. The recip blade of claim 1 , wherein the cross-sectional shape further comprises a third arc-shaped portion.
5. The recip blade of claim 4 , wherein the third arc-shaped portion has a third arcuate shape facing in the first direction.
6. The recip blade of claim 1 , wherein the tang further comprises a tang aperture extending through the tang for coupling the tang to a reciprocating saw.
7. The recip blade of claim 1 , further comprising a tang stem located on an opposite side of the tang relative to the blade body and extending out from the tang.
8. The recip blade of claim 1 , further comprising:
at least one layer of lamination affixed to the tang.
9. The recip blade of claim 8 , wherein the at least one layer of lamination is at least one of copper, nickel, and steel.
10. The recip blade of claim 8 , wherein the at least one layer comprises a first layer of lamination affixed to the tang and a second layer of lamination affixed to the tang.
11. The recip blade of claim 10 , wherein the first layer of lamination is made of a first material and the second layer of lamination is made of a second material different from the first material.
12. The recip blade of claim 1 , wherein the tang is configured to move a bend plane of the recip blade away from the tang.
13. The recip blade of claim 1 , an entirety of the length of the blade body is substantially planar.
14. The recip blade of claim 1 , wherein the cross-sectional shape of the tang is curved continuously across an entirety of the width of the tang.
15. The recip blade of claim 1 , wherein the cross-section shape of the tang is curved continuously along an entirety of the length of the tang.
16. The recip blade of claim 1 , further comprising a transition region in which the curved cross-sectional shape transitions to a substantially planar shape.
17. The recip blade of claim 16 , wherein the transition region is disposed in the tang adjacent a junction between the blade body and the tang such that a portion of the tang adjacent the blade body is substantially planar.
18. The recip blade of claim 16 , wherein the transition region is disposed in the blade body adjacent a junction between the blade body and the tang such that a portion of the blade body adjacent the tang has the curved cross-sectional shape.
