I had to look up those HK blades since I am a fan of and own firearms they make. It seems they are made by Benchmade with the HK name on it. I’ve never tried that style, but just watched a video of it and that’s a pretty cool system!
It is an HK design manufactured by Benchmade. It is a fine blade and has Benchmade quality. I carry it pretty much everywhere, but it’s not a utility knife.
Check your state and local laws if you plan to carry an OTF knife. They are illegal to carry in public in many states, or in certain cities within many states.
Ditto with switchblades, "gravity" knives, and stilettos (two sharpened cutting edges.)
Stupid laws need to be taken off the books, but I'm not the one that's going to sit in jail being morally right...
