Have owned a 806 for a couple of years now. Ususally use it for the normal stuff, cutting boxes, string, rope, etc. Even use it in the garden to trim or cut flowers, etc. Well, this past Friday, was over at my neighbors just shooting the breeze. Was carrying the 806 in my strong side pocket. Was relating an incident where we had chased a "foreign visitor" from out of one of our neighbors truck. As I was telling them of the incident, this "Visitor" decides to park his back-side on my flower planter next to my car. I asked him to leave, and when he refused, I ordered him to leave. His response was to proceed to pull a knife from his pocket. Well, I didn't spend many years in the Navy working with Seals (never was one myself, just spent a lot of time working with them), and not learn a thing or two about personal defense against a knife attack. To make a long story short, the 806 proceeded to spur him to action, and he and his buddy took many long strides out of our neighborhood. Thank goodness for the 806.
