Threadjack, but I've read this in other posts.
My assisted blades open almost faster than you can see, with just a flick of the finger.
How can opneing a non-assisted blade be faster (even with a blade adjusted loose enough to open with a wrist flick)?
The Rat 2 has a strong detent. As you apply force on the thumb stud you build tension until you overcome the detent and the blade flies out. It opens just as fast as any speedsafe knife I've owned.
