Keyhole saw blade or sabre saw blade for a power tool

A saw blade for a power tool, comprising:

• a blade body that includes a longitudinally extending cutting edge with cutting teeth, and a longitudinally extending blade body lateral edge arranged opposite the cutting edge, said blade body defining a maximum blade body height between said cutting edge and said blade body lateral edge;
• a fixing shank configured to fix the saw blade to a power tool, said fixing shank including a longitudinally extending fixing shank lateral edge and an opposing fixing shank edge, a portion of the fixing shank lateral edge and opposing fixing shank edge parallel to each other and defining a maximum shank height therebetween that is less than said maximum blade body height;
• a transition region comprising a transition region lateral edge and an opposing transition region edge, wherein the blade body lateral edge, transition region lateral edge and fixing shank lateral edge form a continuous saw blade lateral edge, the transition region is arranged between the blade body and the fixing shank, the transition region and fixing shank are formed as one piece with the blade body, the blade body, includes a first lateral surface and opposing second lateral surface, the first lateral surface and the second lateral surface disposed between the blade body lateral edge and the cutting edge, the transition region includes a third lateral surface and opposing fourth lateral surface, the third lateral surface and fourth lateral surface disposed between the transition region lateral edge and the transition region edge, said
• the fixing shank includes a fifth lateral surface and opposing sixth lateral surface, the fifth lateral surface and sixth lateral surface disposed between the transition region lateral edge and the transition region edge, and said transition region lateral edge forms a corner with the blade body lateral edge and extends to the portion of the fixing shank lateral edge;
• and
• at least two impressions configured in a linear manner and located along the third lateral surface and at least two ridges defined on the fourth lateral surface corresponding to the at least two impressions, the at least two impressions and corresponding at least two ridges excluded from the blade body, wherein the at least two impressions form a periphery of a geometric pattern that is approximately rectangular and wherein none of the at least two impressions overlap one another.

A saw blade configured to be mounted on a saw, comprising:

• a blade body that includes a cutting edge;
• a fixing shank configured to fix the saw blade to a power tool;
• a transition region arranged between the blade body and the fixing shank;
• a first lateral surface extending along the blade body, transition region and fixing;
• an opposing second lateral surface extending along the blade body, transition region, and fixing shank;
• a lateral edge opposite the cutting edge;
• and
• at least two impressions located along the first lateral surface and at least two ridges defined on the second lateral surface and corresponding to the at least two impressions,
• wherein a depth of at least one of the at least two impressions is at most one third of a thickness of the saw blade.
