I think that Raindrop is correct in saying that there were more than 130 flat grind blades made because the paper that came with mine states, "----------This knife is fitted with one of the first 130 blades that we have made.---------". I do believe that only the first 130 were signed and dated by Chris. Better yet, mine is a left-hand knife with signature and date on the right side of the blade. After checking with Anne, she confirmed that CRK had only sold a total of 5 flat grind blades in the left-hand version.
