ANY knife is potentially dangerous, whether sharp or dull. The biggest danger around knives is really user error and inattention. It is easy to become distracted when using a knife, and to simply take it for granted. Then it's easy to be negligent. This is true for knife aficionados as well as non-knife aficionados.
Last summer, I seriously lacerated the extensor tendon of my right index finger, at the last knuckle, while mindlessly one-hand closing a folder with a Triad Lock. Although its lock might be the most secure when fully opened, it's very dangerous, IMO, to attempt to one-hand close such a design which, when unlocked and in the position I was holding it, slammed closed onto the back of my finger with extreme suddenness. It put me out of work for 4 months, and required months of physical therapy. My finger is mostly normal now, but is still a little bent forward at the last knuckle when the finger is straightened, and I still have to regularly extend and flex it to regain its ROM.
People talk about lock strength, while completely ignoring the inherent risks during the unlocking and closing phase. My accident was completely my fault, not the knife's, but some designs require more care and attention. One should never become complacent around any knives. Often, 'over-familiarity' breeds complacency. I now always maintain a healthy respect for all of my knives, in the same way a zookeeper can like/love the animals they work with, but must always respect the potential for danger.
