Hello, everyone. I am looking at a medford marauder, but the action of a knife is very important to me. Because it has a groove instead of a thumb stud or flipper, it doesn't look like a fast opener. I have seen videos on praetorians that would flip out nicely, but none on the marauder. Do you know if you can effectively flick open a marauder? Also, how much time does it take to break in a medford knife? I would appreciate any answers or experiences with their knives.
