I always thought the automatic stiletto was cool growing up. Finally got one about 25 years ago. Then I bought the Boker because it seemed well-made. That said, the spring is so stiff and that knife so smooth, it’s sometimes hard to hold onto it. Obviously, it doesn’t get much use.
What does get a lot of use, is my Gerber knife which opens with the flick of my thumb. It’s just as quick as an automatic.
