It is a manual opener. It does have a flipper, though. There are no issues whatsoever opening it. Astounding knife for the money. Locks up tight, has a good framelock, uses smooth action, and AUS8 is a functional and easy-to-sharpen steel. Plus it looks good.
It weighs a little more than 3 ounces and it's overall length is 6.25 inches, which may not be your cup of tea. I'm fine with it, though.
