EDC knife is my Benchmade HK. Less than a hundred bucks for a Benchmade auto, I have 3 of these and have put them through the wringer. I love these knives.

Just FYI it's illegal to carry an auto unless you are on duty LEO or on duty military. It has to be "in the commission" meaning you have to be actively on the job.
It's also illegal to possess them unless you fit that category. They are not an "illegal knife" ... which is the misconception, it's its own category of knife in the Texas penal code.
