An excellent review from Everyday Commentary. It really hits on what the whole point of the Synergy1 is. Here is a small excerpt, please click the image for the full review:
Every corner is chamfered. Every surface is very nicely stonewashed, perhaps to the level of Hinderer’s stonewashed over high polish finish on his knives. The parts mate together very solidly. The switch has good feedback and is a medium stiffness clicky. Even the printing is exceptionally sharp. The only lights I have seen that that are the Frelux’s machining peers are the McGizmo Haiku and the aforementioned SPY007. This is exceptionally crafted piece of kit.
