I have a bunch and depending on my mood and where I'm carrying it could be one of at least a dozen. But if forced to pick one it would be the Hogue Deka.
We were in Boston last summer and I chose to bring this one in case I had to "lose" it. They are about the best cheap knife I've used. And I thought I was going to lose it. We were in line to see the USS Constitution. I didn't think about a metal detector there, but it set it off. I pulled it out and gave it to the Sailor working security. He looked it over and said, "That's not a knife". Keep it in your pocket and have a good day.
