a tool, comprising: an X, having an X 1 edge, an X 2 edge, an X first face, an X-second face, an X distal end, an X proximal end attachable to a handle; and a Z guide marking on the X first face that is relative to a line parallel to the X 1 edge.
The legal writings speak so much of the semicolons it makes me afraid of commas. What is the effect of using commas in this example? It seemed appropriate for commas because it was a description of X as opposed to separate elements. How does that change the limits of the claim? Would semicolons instead be better or wrong? Note, I did use a semicolon before the and. :)
Also, If I left out the X 2 edge from this list using commas, does that mean there is no X 2 edge, or can I still describe an X 2 edge in the specification?
Are there any other issues with the claim?
