I'm curious as well. The lack of fuller and non-sharpened clip point is odd, but I'm not an expert on these knives. I find it kind of strange that I'm finding listings on eBay for many 499's that are stamped 3-11, even ones that look real. One seller with 99% feedback (and one I've purchased from in the past) has listings for both kinds (real and questionable), with a $24 difference between the two. Very odd. Hopefully someone more knowledgeable is able to answer.
