Quick question for gents.

Are pocket knives like the one below legal to carry in the U.K.? I've traveled to Germany and Italy with this knife and didn't have an issue but wanted to make sure this was legal in the U.K. before I make the trip in the fall for the game.

I've read the .gov web site and I seem to be in the clear but I've had friends tell me everything from it's completely illegal to carry a pocket knife is common. It's a pocket knife with a folding blade that measures 2.5 inches long.

Above all else, I want to make sure I'm respectful of the laws and customs in your fine country.

Thanks in advance!
