Saw this on Man vs. Wild as well - not why I bought it though... I was looking for a cheap, full tang & full size, titanium blade diving/snorkeling knife for a decent price. This blade fits the bill. As for the quality of titanium - it's hard to tell, but for this price I wouldn't expect high grade. As long as you thoroughly rinse & dry after each use, there is no noticeable corrosion. I bought the yellow handle one and it is brighter yellow than the picture shows - great for locating if you drop it in the reef. The sheath is kind of cheap feeling, but does lock the knife in well & is easily released with a single hand. The leg straps are to small for a 180 lb man's thigh, but hold securely to calf - rubber seems like it might last a couple of years. Overall: a good affordable & lightweight dive knife.
