blade body (20) adjacent to the recessed cutting portion (22)
constitutes the "outermost distal end" of the blade body and
includes the pointed tip (24). Stated another way, as can be
clearly seen in Figure 1 of appellant's drawings, in a
horizontal plane containing the pointed tip (24) there is no
portion of the blade body to the left of the pointed tip and
the pointed tip is thus located "at an outermost distal end"
of the blade body.
Given our understanding of the language of claim 1 on
appeal as set forth above, like appellant, we note that the
pointed tip of the hook portion (64) of the sharpened recessed
cutting portion (62) in Davison is located between the
outermost distal end of the blade body and the proximal end of
the blade body, i.e., the pointed tip in Davison is clearly
spaced inwardly (proximally) of the outermost distal end (60)
of the blade body. In this regard, as is apparent from Figures
6 through 9 of Davison, there is clearly a portion of the
