I purchased my Blue Tang Titanium dive knife about 6 years ago when the price was a diminutive $60 something. I've have used it in hot, balmy weather, wet weather ops, where the bog stuff gets into everything and leaves its odor with you for weeks, been in areas where there was small lake after lake, as well as in the hot, arid desert with nothing but sand and rocks in every direction.as I've also taken my UK BT Titanium on some snorkeling and white water rafting and kayaking expeditions in my off time. It holds an edge like no other, and I've only put one nick on the finish in all these years. FANTASTIC knife! Get one. It's an all-purpose knife, not just a dive knife. You won't regret the purchase price either. I've more than gotten my money's worth out of mine. Cheers!
