For sure, Wa's aren't always thinner than their Western gripped counterparts, but as I said, Wa-"lasers" are almost always.
I'm sorry I hadn't realized you were asking if Mark posted the wrong stats. I thought you had asked, "Are Wa-handled versions of knives typically thinner?".
Regarding your last comment... you totally lost me. "Best" is a subjective term, and I don't see the parallel between blade thickness & overall geometry. But there is much I dont understand...
