I had one plain edge Gator but I've also had a couple of the smaller Gerber GatorMate knives, which I much prefer to the larger Gator.
Good blade steel, well heat treated, grippy handle, lightweight, there are a lot of things to recommend.
Unless the materials failed spectacularly your mate much have been going some to snap the pin - despite their light weight they are pretty tough knives.
I don't like the part-serrated version but then I'm not a fan of serrations on knives to begin with.
Basically I like them as working knives - decent quality, tough and they don't break the bank.
