IMO, in many ways the QC at Benchmade has been improving the last couple years. I don't see the addition of lower-priced knives like the Griptilian as being a bad thing, I can't see how it could be. It's a hell of a tool and is a lot better made than BM's earlier lightweight models (i.e., Ascent series), even the old Panther, which was well-made. Like any company, it has to survive financially, and I would think a large part of that would be to supply the market that produces less expensive but still high-quality working knives. Besides, it's not like the 550 series is a cheapie knife; for most people it would still be a high-end folder.
Back to Elishewitz, I love most of the designs he has done with BM. I am not happy to see him leave the design team, but it's happened and that's it. I will continue to buy BM knives like I always have; if I like a particular knife design I'll buy it, regardless who collaborated on it or if it's an in-house design.
