The handles on my rivoted PSTs are wider than my other PSTs. The awls are also different. The can openers on the rivoted are different as one is left handed grind and the other is right handed grind. The left handed grind can opener has hollow rivots, US PAT 4238882 and Leatherman only on the knife blade. The right handed grind can opener has solid rivots, REG`D TM 1325473 and Leatherman Japan on the knife blade. But as mentioned by Nomad this is discussed in the above sticky. Seems to be a alot of variations in the PSTs.
