My wife and I went to the beach last week and the 710 went along as a "I paid $8 for it so it won't break my heart to lose it" piece. I used it all week, for things like cutting open packages or fishing line to cutting up a 32oz t bone. It spent between 6-8 hours in the Gulf of Mexico. While it got a few spots on it, they cleaned off easily, even after that much salt water immersion. It stayed VERY sharp all week and performed like a champ. I would recommend this little knife to pretty much anyone!
