It's really, really easy to pull the knife from your pocket without it opening.
On some models, you have to try really hard to get the wave to engage.
This.
I don't understand why people think just because you HAVE a waved knife you have to wave it open every time you use it.
I also don't understand the (mocking?) dismissal of it as only for fighting / "tactical" uses.
I find it useful for things like working on a ladder....pull knife out and it's open, close it and back in the pocket. Sure I could open almost any modern pocketknife one-handed but like virtually everything on most of the knives we buy it's a convenience (as is a thumb disk, lock, fancy steel, etc).
