Dymondwood 300 series

Have they been changed recently? I thought they used to have 2 pins, newer models have 3 pins (center pin added).

You actually have that backwards. The Dymondwood versions were introduced in the 2009 catalog and had three "pins". The following year, 2010, they were changed to the "two" pin versions and they still use that configuration.

Here is what all but the sawcut scales look like naked. The spring pin is a tapered head in tapered hole with the opposite end punched in center and spread open to secure pin. The sawcuts have no pins because the scale shield is actually a pillar of metal attached to the liner and the Valox scale is hot pressed over it and there are plastic studs. So the pillar helps hold the scale on. All thru scale pins are roll spread by pressure on the head to secure them to the liner. Sounds like I work there doesn't it, but not so, I have stripped down several to put on some custom scales. 300

This shows the date change in 309s from 2008 to 2010

This shows the current liner with two pins and one side of the hidden spring pin. The other side has a solid head and this side is the hollow head punched spread to secure it into place.

Reverse side to show differences in spring pin heads. This is the solid head.

This is how they hold the sawcut scale on in lieu of pins. The scale likely has a moulded in plastic studs that fits thru a liner hole and is hot pressed to spread it out and make a head inside the liner wall. This occurs in four places on the back liner and three places on the front liner in 301s and 303s.

Thanks for the responses, gentlemen. So I guess the 3 pin knives are a bit of a collector's item.
