I assume you mean buy them here? You'll have no problem buying those knives if you can find them. Regardless of the letter of the law, I'd think hard about whether you really need to carry something as big as the opinel. The police have a lot of discretion on what they can choose to hassle you for and unless you have a job or something that really requires it, you might be asking for trouble. I might even choose something smaller for the victorinox. There's a lot written on NYC issues in these forums, but the the quick take is: "Do not have your knife visible at any time in public."
