I've been trying for 6 years to land a GSO 4.1. There are numerous posts complaining about tremendous wait times and the business model. I can't comment on that, but I can say I got on their site 6 days ago and saw they had some 4.1 seconds. I ordered one with brown micarta scales. The knife arrived today. It's perfect. If there are issues that caused the knife to be sold as a second, it must be under the scales, because the knife looks flawless to me. The scales and ergonomics are spot on. I am already planning on selling two similar knives I own, a Fiddleback production Bushfinger and an original GNS, because of this knife. It's an instant favorite.
I also have a Sagewood drop loop on order.
