I don't mean throw a wrench in the mix, but don't forget the Rat Shop HR Variant with a serated spine, they were all Gen 2 with Res-C and all black. there was 4, 5, and 6 pattern serations. I don't have one but I came close. I have a Gen 2 HR I got at Blade west 2005 and I love it it was my first Busse family blade.
