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.

Great buy

Like everyone else i wasn't expecting much. But when i finally got it i was very impressed. Opens fast and solid. I carry all the time now. For 8 bucks this is definitely worth the buy

My new EDC

I wasn't expecting much when I purchased this knife. When it arrived I was pleasantly surprised. I put it in my pocket to try it out for an EDC, and it became my new EDC. I was impressed with how sturdy the whole knife felt. The spring assist was quick, the blade was sharp, and I loved everything about this knife. I have used this knife day after day over the last year. The only signs of wear are some of the black has chipped off of the pocket clip (very little along the edges), some black has wore off of the blade (about a 1" long thin line), and some minor scratches to the gray frame (hardly noticeable). I was ,and still am, so impressed with this knife I ordered another just for a back up, but unless I do something stupid I don't think I will need the back up. I would recommend this knife if you are in search of an EDC, or even just one to have around.

Better than you'd think

For 8 bucks I wasn't expecting more than a gas station special. But it's surprisingly good. Solid, sharp as hell, and the assist is flawless. What was supposed to be a temporary EDC, became my favorite knife.

Great knife

its a great knife but i opened it about 25 times and the screw by the glass breaker popped out. but overall this knife is a great purchase and a little glue will stop that from ever happening again

Great steel

Very good blade and comes out of the package razor sharp. Quick opening but a little bulky but I'd still buy another one

Worth 3 times the price

Best rapid-deploy blade ever IMHO and I have had some VERY HIGH END EDC's. Just has a fantastic feel in hand and has more weight than most other brands, but the heft comes in handy when tasking the knife in camp, etc. Even throws very well!! Buy this now.....or buy a few at this ridiculous price!!! Solid EDC
