[QUOTE My Gamerx I inherited has a third pin but the wedge is the same round spacer as the third pin haven't seen it anywhere else either just, a style I spouse.
I read the third pin was a spacer more for celluloid scales to help prevent them distorting not to stop the blade .[/QUOTE]

I have seen that pin substitute for a wedge a few times but not very often for sure. Unique and interesting idea, isn't it.
