Question: flip open tab for right hand or dual sides for left handed
Document: The liner lock mechanism is designed to lock the Tanto blade firmly in place when the blade is extended. The mechanism locks the blade into place by sliding behind the blades tab that assists opening the blade. Crimping on the lock mechanism indicates where to push against the handle to close the blade. Thumb Studs The thumb studs on the knife are used to help assist opening the knife. The studs on the Gerber Evo Tanto blade are ambidextrous allowing it to be easy to open with his or hers right or left hand.
I purchased this knife for my husband for Christmas over two years ago now and it remains in his daily carry still quite sharp with an occasional sharpening of the blade. The finger flip makes this knife incredibly easy to open one handed. Gently press to open and use the thumb stud to open all the way or with a simple flick of the wrist and firm pressing of the &#34;finger flip&#34; to flick the knife open completely and easily one-handed.
I really like this knife, I got it for work and it fits the bill perfectly. Right out of the box it can easily slice through anything I need it too. It fits perfectly in my pocket and my hand and it easily opens with 1 hand thanks to the lever which is a big plus for me because I'm not a huge fan of thumb studs. It is weighted wonderfully I like to flip my knife over when i'm bored and it is so easy with this one.
For about 20.00, you can not go wrong. Super light weight, easy to open and close one-handed. Fits easily in your pocket and your hand. Great ergonomic grip.The blade is almost 4 fingers long (I'm 5' 7" with decent meaty hands)Sharp blade. I havent really put it through the paces, but it feels well constructed and again...for 20.00 or less, it's a GREAT knife!
By far one of the best pocket knives I have ever found. I have bought 4 of these in the past, two for my own use and two as gifts. The blade is easy to sharpen and holds an edge well. The stud on the bottom of the blade prevents forward hand slip, a feature I wish more pocket knives utilized. Dual thumb studs on both sides of the blade and the blade lock is notched to provide additional grip.
I ordered this knife and it am very happy with it. It came 1 day before the estimated arrival date so shipping is pretty fast. The knife is a perfect size for me, i am able to very comfortably hold it. This flip feature is great since a lefty would have a harder time using the thumb studs due to the belt clip on the left side. It flips out with just a flip of the finger, no other motion involved which i really like. Love the tanto blade.
I thought 3.15&#34; was bigger than it really is. The open assist is just a tab on the back which was disappointing. The lock has to be coerced in to working correctly. Seems sharp. Can't speak for how long it stays sharp.
even though its only about an inch smaller than the normal sized evo by gerber it is kind of smaller than I'd like. That being said it is a great knife. I love the finger flip open ability, a lot of people think it's a switch blade until I show them the knife and they see nothing assisted in opening the blade (it is one of the reasons this is the 3rd evo knife by gerber I have bought). All of my gerber knives have lasted a long time and are still going.
I received one of these knives a few years back from my wife, a coworker had one and I liked the easy of use, one handed opening versus the knife I had been carrying at the time. I had a screw fall out of mine and bought this as a new carry knife. My old one will be good for parts. Few drips of gun lube and they open super fast. I even bought my wife one. You won't be disappointed with this knife and it's a great addition to your EDC.
It was sharp out of the box and has held up nicely. Arrived right on time no hassles. The serrations are tough and work well to cute any rope. It was a little smaller that I thought it would be and is a little difficult to hold in my hand comfortably but it is indeed a great knife for it's price and in general.
Answer: yes
