OPINION
In reaching our decision in this appeal, we have given
careful consideration to the appellant's specification and
claims, to the applied prior art references, and to the
respective positions articulated by the appellant and the
examiner. As a consequence of our review, we make the
determinations which follow.
Claim 1 reads as follows:
1. A tool component comprising an abrasive compact having a
flat working surface presenting a cutting edge around its
periphery and an opposite surface bonded to a cemented
carbide substrate along an interface, a recess extending
into the cemented carbide substrate from the interface
filled with abrasive compact and having a central portion
and an outer portion, shallower than the central portion,
which defines, in plan, at least one substantially wedge-
shaped configuration, the configuration having a narrow end
coincident with a side surface of the component and sides
extending into the component and diverging from the narrow
end.
