The Tenacious might even get from me five stars if I did not recently 3000 Lightweight had bought me the Boker Plus. For the comparable price the Boker offers a bit more solidity (wider blade), great design and top-notch processing. In contrast, the Spyderco acts a bit spariger, but is undoubtedly also a very solid knife with good liner lock and to act generally good. The 8CR13MoV blade from China can be reduced to a very good sharpness (sharpened after purchase), on the edge retention, I can not say much Nocht. And of course: As a hand knife with lock, it is in Germany for legal reasons somewhat problematic to perform in public (even a plus for the Boker, which has no explicit opener for one-handed opening and must be generally open with both hands, what chance the increases that it will not be contested at a control).
