Concrete stamping tool

An apparatus for producing impressions in concrete or the like, comprising in combination:

• a base member having a lower surface;
• outer blade means, coupled to said lower surface of said base and defining a closed area, for cutting an outer channel having a first cross-sectional geometry in said concrete;
• inner blade means, coupled to said lower surface of said base and situated within said closed area for cutting an inner channel having a second cross-sectional geometry in said concrete;
• and
• wherein said first cross-sectional geometry is a bisection of said second cross-sectional geometry.

An improved apparatus for stamping impressions in materials such as uncured concrete, comprising in combination:

• a base member having an upper and a lower surface and an outer periphery, said outer periphery having a shape which provides a repetitive keyed pattern which may be fitted together with tools of similar shaped in a plurality of locations;
• a plurality of inner blades, each having a predetermined
• crosssectional geometry, each coupled to said lower surface of said base within said outer periphery;
• and
• an outer blade coupled to and surrounding said outer periphery of said base member at said lower surface, said outer blade having a cross-sectional geometry which is a bisection of said cross-sectional geometry of said inner blades, so that two adjacent tools abutted one against the other produce a composite blade at their border which has substantially the same cross-sectional geometry as that of said inner blade;
• said blades and base member being made of a flexible elastomeric material;
• means for attaching a handle to said upper surface of said base member;
• and
• a strap handle coupled to the upper surface of said base member.
