Lamination Question
i posted this pira a couple weeks ago and i finally got to etched it this past weekend. well, i found out that it is indeed laminated and i believe it is what you folks refer to as sandwich type lamination (due to the edge erosion)? what i don't get are the horizontal lines that's running parallel to the blade. what are those and could someone tell what type of metal was used for the blade? is this an older or newer blade? thanks in advance...
