I learned of Shwoodshop products thanks to an ad in Ski magazine nearly two decades ago (circa 2008). The first edition product had a durability issue, but the designer at Shwoodshop solved the problem with what appears to be metal (aluminum?) inserts in the frame and temple pieces. I know they are quite durable now, after a particularly embarrassing face-plant while skiiing at Colorado's Mary Jane mountain. Unlike my pride, the woodies emerged from the mishap unscathed. I shall remain an Shwoodshop customer as long as they keep pumping the Canby style out.
