I noticed the pictures of the new ka-bar bk9 shows a different grind and was wondering if it is in fact correct examples of the final product and if so is the spine thickness left the same? I know the grind was changed on the neckers to a full flat with a slight increase in thickness but if the photo's of the 9 are correct and the spine is still at least as thick as the old Camillus beckers it shoud have some added strength. Thanks for any info, Scott
