I have several Benchmade knives and absolutely love them all. Have an Auto Adamas, a Shootout, and an Autocrat. I use my Shootout daily as a work knife and it is spectacular! I have never had to use anything other than the polishing stone and leather strap to get it to shave like new. Usually do this about every 3 months or so.
Recently we have got turned onto the Microtech brand and they are great as well. We have an Ultratech, an Exocet Sand Trooper, a Hera, and a Dirac Delta. I have one of these with me everywhere I go and they have never opened in my pocket. None of the OTF knives have safeties but the throw on the switches are long and deliberate enough that they don’t fire by themselves but always fire when I need them to. The Auto Adamas does have a safety and it is always on before going in my pocket, that way I remember to turn it off when pulling it out, kind of like a trusty 1911.
The Microtechs do seem to have higher quality materials and the blades are super strong. As I use all but the Shootout for defensive tools only, I have never had to sharpen one.
