How are Spring Assist different from a Gravity Knife or Automatic Switchblade Knife?

Gravity or Switch Blade knives feature a button, level, or other type of switch that releases a spring pressure to automatically open the blade. On a Spring Assist knife, there is no separate button or switch. Instead, you apply pressure to part of the blade to begin the opening process. This is usually a small bump of metal which sticks out under the knife, making it fast and comfortable to use. Once you press on that part of the blade, it automatically opens and locks into place. Since the action of opening the knife is started by pressing the blade metal, instead of a button or switch, it is considered to bypass the laws which ban Switch Blade knives.

This knife is great. It seemed a little small in the photo however it easily holds its own amongst my collection.

I bought these as presents, and they are nice. I didn't have any of the issues other people have posted about having to tighten screws to keep everything together. The blades were decently sharp, although I would probably sharpen it if I was going to keep it.

Personally, I was only able to open the knife quickly using my pointer finger. When I tried to open it using my thumb, I could only open it halfway. But I'm not too broken up about it, as my of the videos I saw on youtube, people would open their knifes with their pointer finger.

Overall, very happy :)

This knife is really great for thrusting because of the flared base and the ridged handle. The flared base also makes it much more easy to flip out compared to other spring assisted knives I have. It has High quality carbon steel and it came oiled. Great buy, I recommend purchasing this item.
