Frank B is not wrong

The 618 is an outstanding knife. The detent however is not consistent. I own two 618ís. One all black and the other black blade with non finished grip. The all black 618 detent is Extremely stiff and canít be opened with one hand. The other 618 opens smooth and quick with a flick or the thumb. Iíve been trying to figure out why the detent is so hard to get open on the all black but I canít figure it out. Hopefully it works loose with time.

This is a wonderful slim gentleman's style knife. To the guy who gave it 1 star, I think you are opening it wrong. You have to push straight up on the thumbstud. It will then fly open no problem. But remember that the tolerances on this knife are amazing and you have to break it in. I opened and closed this knife over 2500 times to break it in smooth. Also, the part of the frame where the blade meets has zero signs of wear and absolutely no blade play. Check you tube videos to see how easy this thing opens when broken in.
Unimpressed--the detent is way too stiff...STILL

I normally prefer flipper knives, as they typically have far greater purchase on the blade-opening mechanism. But the styling of this knife appealed to me, and other reviews indicated that the snappy detent afforded rapid blade deployment. I hoped that by proper lubrication and working the knife, the detent would smooth out. Nope...it's still almost impossible to open the knife with one hand.

Also, I am not confident about the lack of a blade stop pin. The knife uses the titanium frame for this purpose. I wonder if repeated blows by the blade shank would loosen up the fit over time, with resulting blade play.

Now for the follow-up. BladeHQ's customer service team did an excellent job processing the return of this knife. The company is excellent and I will continue to do business here.

But I had hoped that this problem was an anomaly, so I ordered a replacement. The second knife was only barely better than the first one. Because this knife has a frame lock, the lock bar is exposed. It turns out that if any finger makes even slight content with the lock bar, the knife becomes impossible to open with one hand. The proper hand position is difficult to achieve consistently, and this negates the advantage of rapid blade deployment.

To the fellow who offered thoughtful suggestionsó
Thanks. I looked at all the youtube.com reviews before making the initial purchase. Itís true that others seemed to be able to open the blade by pushing the thumb stud towards the pivot pin. But in one newly-posted review last week, the reviewer indicated the same problem as I hadóthat the thumb stud was sharp (proprietary star-shaped screw), it tore his thumb, and the knife was difficult to open. He pointed out that other reviewers may have had more calloused fingers (mine are not). Iím glad that you were able to smooth out your knife by opening it 2,500 times. If I did that during the first three weeks of ownership, my right thumb would be a bloody stump.

So I have kept the second knife in the hopes that in the next several weeks I can open it enough times to get it to smooth out. If I canít, Iíll seek out a friend with tougher fingers and sell it to him. That would be a shame; itís a pretty knife. But for now, Iíll maintain my one-star rating:

For this price point, I expected better engineering and design. In the meantime, I'll stick to liner locks, with either assisted openers or flipper openers.

To Chris B--
I feel vindicated to find that someone else has run into similar problems. Please pay attention to the position of your other fingers when trying to flick open the knife. My problem has always been that my knife is difficult to open if any of my fingers make the slightest contact with the lock bar. It remains difficult to place my hand consistently to avoid this problem.
