Customers are mixed about the ease of opening. Some mention that it opens so easily, you may not want to risk it opening in your pocket. They appreciate the unique SOG locking mechanism and the smooth blade opening action. However, others say that the knife didn't seem to open smoothly with the flipper, the blade didn' t fully open to the locked position, and it was very difficult to close the blade with one hand as the lock release.

quite robust
4 Stars
quite robust
The blade locks in the open position. Unlocking the blade to close it requires significant pressure on the blade release on the back of the knife - see picture. No instructions came with the knife, but the purpose of the lock release is obvious. However, it took me a while to get the release to work. Trying to push the serrated release down far enough with my thumb was painful. What worked was using the side of my index finger - see picture. People with battle-hardened hands will no doubt laugh at this review, but just saying.. Promotional videos showing the blade effortlessly snapping open and close are a little misleading.When I unpackaged the knife there was a tiny screw loose in the package which I was able to re-attach. The knife is well constructed and for its size has a definite heft to it.

5.0 out of 5 stars Nice little assisted flipper. Shaving sharp and great size for easy carry.
Reviewed in the United States on June 28, 2019
Style: Twitch II - Aluminum HandlePattern Name: KnifeVerified Purchase
Overall this pocket knife is perfect for the office or when I don't want a bulky carry. While still dangerous (be careful) it is too cute to appear threatening.

Open: it is about 6 and 1/4" long (157mm)
Closed: it is about 3 and 1/2" long (90mm)
Weight: ~2.5 oz

What I like:
1. It is very sharp! The AUS-8 steel is fantastic.
2. It deploys reliably and quietly.
3. It has a lanyard hole
4. It fits well in the coin pocket of my jeans
5. Solid Thin Design. Not counting the clip and Axis bolts, the knife from scale to scale is less than 9mm thick. (~1/3 inch). Including the Clip to scale it is 12.8mm thick.
6. It has a Safety lock to prevent accidental deployment.
7. Low level of play in blade & hinge.

Neutral feelings:
1. The Spine lock enforces safe two-handed closing. It can be unlocked and closed with one hand but that is only recommended for experienced chainsaw jugglers.

Minor gripes:
1. I would prefer the spring steel to be a little snappier, however it deploys reliably.
2. blade centering when folded is slightly off center. As far as I'm concerned this is cosmetic only.

This seller provides outstanding customer service and they stand by their quality. I will buy from them again. They quickly sent me a replacement after I experienced an issue with my first shipment.

5.0 out of 5 stars Best EDC folding knife I have ever owned!
Reviewed in the United States on February 10, 2024
Style: Twitch II - Aluminum HandlePattern Name: KnifeVerified Purchase
This one is the second one I bought... I still have the first one, more about that in a minute. I should qualify something first. I have a CRKT M21-14 tactical knife I got while in Iraq which is equally as good, just for a different purpose.

I bought my first Twitch II also when serving in Iraq but for a another purpose. A colleague, who I worked with, brought this knife to my attention. In many parts of the world and in some states in the U.S. it's illegal to carry a knife with a blade over 3". Being under 3" and with an unassuming lower profile makes it a perfect EDC carry knife. It's quick to deploy in a life or death situation but still legal in length (the assisted blade isn't legal in some states). If you had to defend yourself in court... an unassuming small knife shown to a jury is much better than six inch silletto blade or Rambo knife.

Why I own two... I keep the new one (never carried or used) in my shaving kit for when I travel and packed in my checked luggage. This way the knife is as sharp as when it was manufactured, razor sharp in this case.

For the size, toughness and reliability it's an all-around great knife.

I like this knife. I almost love it, with only 2 complaints. The quality and finish look great. Its really good looking. The blade is sharp. It flips open quickly and smoothly. What I don't like (but other reviewers do seem to like) is the safety catch. I kinda understand it for when the knife is open, if you're worried you might close it on yourself by accident but I hate that a few times I've pulled the knife out to use it and somehow I'd inadvertently turned the safety catch on, so i gotta flip that little safety lever off. It's easy, but annoying... the only other thing I CANT believe is other reviewers like the size..??? WHAT?? For a dude I have small hands. Not smallish - i mean small. I wear small gloves. My wedding band is pretty small. I have small hands.... this knife feels like I'm holding fingernail clippers when im cutting something open. I wish it were about 20 percent larger. It's tiny. But I don't regret buying it.

5.0 out of 5 stars UPDATED to 5 stars, read updated review.....Was stiff to open
Reviewed in the United States on May 15, 2019
Style: Twitch II - Aluminum HandlePattern Name: KnifeVerified Purchase
This aluminum knife was stiff to open and difficult to grip. The aluminum side panels are slick and don't allow a good purchase on the knife when trying to flick it open. Returned and purchased the rosewood one....much better.

UPDATE 5/20/19: Seller ProMark sent me a couple of emails after my purchase and I corresponded with them regarding the knife. I noted what I thought was wrong with the knife and informed them that I had already purchased a Rosewood handled version rather than take a chance on another of the same aluminum variety. I was/am happy with my Rosewood handled purchase and thought nothing more of it. Then on the 5/17/19 ProMark contacted me and asked me if I would reevaluate the knife if they sent me another. I said yes and received the new grey colored aluminum handled knife in the mail on Sunday the 19th.

I opened the sealed box and went right for the flaw in the first one. I flicked it open using the "kick" and it sprung into action and locked into place. Then the knurled stud on the blade (I like this better than the kick as it is a more natural feel) and it also sprung open and locked. The replacement knife was working just as good as my rosewood handled version and did not feel slick to me at all and was easy to grip. The only thing I can figure out is that the reason I could not originally get a good grip on this small and smooth knife was because I had to exert way too much force to get the original knife to open and lock. Anyway, I am not encountering any of the original issues.

Just for information, the aluminum bodied knife handle thickness is 8.5mm. The Rosewood version is 9.8mm. That extra 1.3mm from my perspective makes the rosewood version a little more comfortable but that is just personal taste, hand strength and hand size...everyone. will be different.

I did buy this specific knife after a lot of shopping because of its size. I wanted a small knife. That however comes with trade offs. The biggest negative of the knife is that you need two hands to unlock and close it. I personally would prefer being able to move the lock aside with the one hand to release the blade like most of my cheaper knives but the cost of that would have been a thicker body which would make this knife less attractive to me.

In summary I think that the Twitch II is a great little pocket knife. Had the first knife I received been like the replacement I would have rated it at 4 stars , mostly because of the unlocking feature. The customer service was outstanding, communicating early and often and I give them a 5 star rating and because of that I'm going to rate this knife as a 5.

Stichwortartig meine sehr guten Eindrücke zum Twitch 2:

* ist ein quallitativ sehr hochwertig
* sehr angenehm zu bediendende Mechanik
* Bedienelemente sind sehr griffig, keine scharfen Kanten
* Kompakt, kurz, trägt nicht auf
* sehr scharf
* sieht 'zivil' aus

Zusäzliche Hinweise:

* Bedienungsanleitung fehlt, ist aber für durchschnittlich intelligente Benutzer auch nicht erforderlich
* Vorsicht beim Öffnen mit den Daumenstiften: Geht wegen dem federgestützten Öffnen sehr schnell auf. Unachtsame können dabei vom Stift abrutschen versehendlich in die sehr scharfe Klinge packen. Empfehle zum Öffnen den Flipper zu benutzen.
* Messer hat Lockback Sicherung
* das Messer hat eine Schiebe-Sicherung hinter dem Lockback-Riegel, die ein unabsichtliches Öffnen des Messers verhindert
* Das Messer ist nicht Waffengesetzkonform und darf in Deutschland nicht 'geführt' werden.
