Help Deciding Which Knife To Buy

[xmoyerboys]

Vey sorry for this possibly being in the wrong section it is my first post but I am curious about a few knives. The knives are the Hinderer XM-18 Gen 4, the Strider SMF, and of course the Chris Reeve large Sabenza 21. I know these knives are all very amazing and all have a ton of pros and a few cons. I also know that these knives are a bit different as far as what they would be used for. Additional information about what I need is that I live in Florida right off the beach so corrosion is a problem. Also I do what I good knife for EDC as well as in a tactical situation. Also I will be joining the military in a few years and while I will most definitely be purchasing another knife I am still curious to hear any opinions on all these knives.
