Atomic Aquatics Titanium Ti6 Scuba Diving Knife - Corrosion-Resistant Titanium Dive Tool for Underwater Safety & Emergency Cutting | Perfect for Spearfishing, Wreck Diving & Marine Exploration

PERFECT.About me: I am 38yrs old, 5'9", 180lbs., I have an AAS in HVAC Technology, BTAS in Technology and Leadership, I have worked in the maintenance field for 10 years.Knife: although never tested in salt water, the quality speaks for itself. I wear a Citizen titanium watch everyday to work. I beat it up, and it is lighter and way more scratch resistant than stainless. When deciding which knife to buy, money was not an issue. tangling with a shark in Florida and having protection was. I swim around the Tampa Bay area, and trust me, there are all kinds of sharks out there. The knife is awesome. I have played with it all day. The sheath is plastic, but it works. I have read other reviews about the quality of sheaths, and handles. This knife is extremely well designed, and the quality of the components are the best. I usually test a knife's sharpness by shaving some hairs on my arm. Out of the box, it wont do that, but this is not a razor, it is a shark piercing tool. It is sharp, but not razor sharp. I bought my dad a Cutco fishermans solution, and he has filleted hundreds of fish, and it is still razor sharp. You can cut yourself. It is perfect for piercing, and line cutting. The quick release is flawless. One finger, awesome design. The rubber straps are so secure, they will pull the hairs out of your legs. It is secure, in the sheath, and on the body. I looked at the US DIvers titanium knife, and it just seemed junky. I am glad I payed 30 dollars more for this knife. I have somewhat larger hands, and it fits perfect.Can't say enough good stuff about this knife.I have ordered a lot of stuff from Amazon, and never taken the time to do a review. i felt that after reading the reviews that guided my decision to buy this knife, I should give back. This review is also based on my happiness with my purchase. I thought Cressi was top of the line, until I got this knife. Cressi is junk compared to this quality. I will probably at least get a new mask from Atomic.One more thing:; the straps. The cant make straps that fit everybody. They fit my calves, but not my thigh. My thighs are huge, prob be perfect for a skinny guy. The reasoning behind Atomics length limits: if they made them big enough to fit everybody, the skinny guy would have an extra foot of slack. You dont want to cut it because you might want the extra length for another body position someday. PERFECT. Badass Knife. Thanks Atomic
