Although it is possible to remove it with a flat headed screwdriver, that is more time consuming than using a specialized tool. In order to test the tool, I picked up this British made ale at my LBS (local beverage store).
I don't know where you buy your beer, but up here in Oregon there are many (local) brews without twist-off caps. Generally speaking... if you can twist off the cap it ain't worth drinking. I'm sure some are exported to California.
