(under subclass 861) Method or apparatus wherein the tool utilized functions to penetrate a thickness work surface only and is constrained in its cutting stroke, or in its movement relative to the work to a path lying between the nonthickness work surfaces so as to define product laminae.
(1) Note. It is not required that the tool proceed completely through the work, i.e., width and/or longitudinal extent. The requirement that laminae be produced is significant.
(2) Note. The definition of the term "splitting" may be different in other arts; see, for instance, that relied on in Class 69, Leather Manufactures, subclass 9 wherein a cutting path parallel to the work surfaces is required.

879, for a cutting tool which enters a thickness face but fails to produce a lamina, as by merely cutting a groove.
