  We construct knot invariants on the basis of ascribing Euclidean geometric
values to a triangulation of sphere S^3 where the knot lies. The main new
feature of this construction compared to the author's earlier papers on
manifold invariants is that now nonzero "deficit angles" (in the terminology of
Regge calculus) can also be handled. Moreover, the knot goes exactly along
those edges of triangulations that have nonzero deficit angles.
