The Sketcher BSplineComb tool shows or hides the B-spline curvature comb in all sketches.
The curvature comb indicates the curvature (value of the second-order derivative) along a B-spline. The higher the curvature, the longer the comb's teeth are. Where a B-spline curves to the right the comb is on its left side and vice versa.
B-spline with a saddle point at its midpoint, the curvature comb is zero there.
