The Boker is the only one that uses the liner lock. The Spyderco & BYRD brands use lockbacks I believe. That was one of the main reasons I was asking about it. The BYRD knives are cheaper as they are made in China & use more common & cheaper steel in the blades, like 440C, 2cr13, AUS-8, ECT. All good steel . But not like H2 or AG10! As I am on a very tight budget, those BYRDs are attractive! I picked up 2 back some years ago. ( not hawkbills ). That were very nice, they were lockbacks & were put up for grandsons. If anyone has that Boker Bat I would still like some information about it. Or if someone has the Spyderco Spyderhawk I would like to know about it . I would even consider buying one if I can find one. Thanks for the information about these knives .
