This is the tool I carry day in and out because of the hex bolt feature  I've customized by removing the straight blade (There is still a serated  blade) and replaced it with a saw and a seatbelt cutter. I sail competively  and the seatbelt cutter gives me a safe way to cut a line. With the hook  end on the blade the line won't come off until its fully cut through. (Oh  yeah, the basic knife comes with one open slot for customization.)
