It took nearly 40-years but I finally found it: The answer to my "holy blade search".  The design of the 9-10-9 is altogether unique in the industry, employing two aerospace industry micro-carbon layers sandwiched between three thin slabs of the choicest vertical grain Cypress available.  The result is nothing short of magnificence!  A blade with the feel and power of a classic single-ply, the oversized sweet spot and power of carbon.. all in an unsplittable package.

Can you guess that I'm ecstatic about how the 9-10-9 turned out?!  It's no wonder that I play with one myself (and I've got a sizable quiver of blades at my disposal, as you might imagine).
