Well, that's what I'm talking about. "Shouldn't" is certainly great, but if wishes were horses, we'd all ride. Unlocking and closing a crossbar lock (AXIS) knife is objectively easier, safer, and quicker than closing a framelock because at no time are your fingers in the path of the blade's travel, unlike a framelock. Bear in mind that I say this as someone who A. has many more framelock equipped knives than crossbar lock knives, and B. who is has a framelock knife in my pocket as I type this. Your thumb is in the blade path, and many people here have been bit (or have had people they allowed to look at one of their knives) when a blade on a framelock they weren't familiar with, swung closed more quickly than they were ready for before they could get their thumb (which had to reach across the blade path of closure, to depress the lockbar) out of the way. I have never had a cross bar lock knife present this issue.
