Knife too smooth

In this context, free dropping with no resistance. Gravity makes the blade fall. CRKs are smooth too, but more of a hydraulic smooth and not gravity dropping.

This doesn't make sense. Free dropping is different than smooth. Maybe frictionless? Or just free dropping.

I would not consider alot of bearing knives as smooth, for instance the Anthem as it feels gritty with those bearings. And there is no detent.

But then again... Smooth can be the detent is smooth riding on the blade on open or close. Which no one really explains or understand this.

Smooth I would say is usually going to be a term used for most frame or liner lock knives on washers. Such as a CRK as an example.

But everyone just seems to say any knife is smooth regardless of any definition or traits actually exhibited.

Po-tay-toe or Po-tah-toe. Smooth is just a loosely-used adjective to describe the opening/closing action of a knife. On frame or liner locks, it's not so much the blade riding on the washers than it is the friction of the detent ball riding on the blade.

It happened the first time I was introduced to a Spyderco POLICE. I held it open, parallel to the ground, released the back lock and the fully serrated blade swung nearly 180 degrees and cut the snot out of my forefinger. Bled all over the place. I had never seen a blade on a folder that would drop past 90 degrees.
At that moment I knew that I had to have one.

A police bit me in 1996 or so the first time I held and closed one same as you. Had never seen a blade swing that far at the time and was not expecting that at all.

Whats up guys,
I recently picked up a zt 0562cf and man is that thing smooth. I know there are smoother/nicer knives out there but this is my nicest flipper at the moment. The action is so nice, its scary lol.
Before this i usually edc'd my benchmade which is smooth in its own way. I like benchmades because i've gotten used to the axis lock which i use both my thumb and pointer finger to disengage the lock to close the blade.( i know you can use either finger)
Well when i was carrying the zt the other night, i was disengaging the frame lock to close the blade. I usually simultaneously push the lock with my thumb and start closing the blade with my pointer finger. Well as I was closing the knife, I pushed the blade with my finger like i always do but since the action is so fluid, the momentum gained by my slight touch plus the blade weight, it closed while my thumb was still in the way. Luckily it wasn't serious this time but I can see how with a bit more force it can do some serious damage especially if you have a scary sharp edge. Now im always conscience about closing this knife.
Have any of you guys done the same thing? What kind of knife was it? Was the cut serious?
Thanks for reading. i just wanted to share my story about my zt0562. Its such a nice knife.

Did the exact same thing when i first received my ZT 456, it snapped so fast back on my thumb cut it not badly but it sure hurt.
 
I think most people have figured out that the way the detent rides on the side of the tang of the knife is a major factor in smoothness.

The way I see it there are two sensations we feel when describing a knife as smooth.

Freeness of action: how freely does the blade swing? On liner/framelocks the action will typically be more free if you hold the lockbar off the tang

And

Actual smoothness: how consistent is the feeling when opening in being free from any grittiness or bumpy feeling when opening? Is there parts of the opening arc where the action offers inconsistent resistance at some point of travel?


Actions can be smooth but not free, this is the famous Hydraulic action

Or sometimes free but not smooth like actions that swing freely but you can feel the bearings going bump bump.

It's something I'm aware of when closing a frame or linerlock. Even more aware when carrying the 0560, 0562cf or 0452cf, because as you have noted, they are damn smooth. I don't have a flipper on me at the moment so I can't confirm this but I believe you can place your thumb in such a way that the flipper tab contacts you thumb rather than the blade.

I keep my thumb nail under the blade until it makes contact then I Finnish closing it.

Haha I’m glad I’m not the only one. I felt like a total noob.

I think it's safe to say that we have all been bitten before. I was at Cabelas checking out a ZT 0462 CF when I got bit, bled all over the counter so I took her home with me. It was Love at first bite;)
 
I recently got the Boos Blades Hound. I constantly catch the blade of it with my thumbnail. No flesh yet but it feels like a matter of time.
 
Zero Tolerance makes some excellent knives. Most of their flippers set the bar for smooth flipping action especially at the price point. With ZT you usually get fairly high end materials/blade steels for a great price. I have to admit since this thread mentioned Zero Tolerance I just had to browse and see if a certain someone had posted any contrary comments just to be indifferent to ZT in general(define smooth):rolleyes: The definition of smooth; Zero Tolerance

To others things about ZT you said, I agree. The smoothness, however, is due more to the ball bearing than to ZT.
 
If you move your thumb closer to the blade when you’re engaging the lock bar, the flipper tab will hit your thumb instead of the blade’s edge.

I disagree with you the 0850 and the 0640 are my smoothest ZT and don’t have bearing. The 0562 and the 0801 are great flippers and are smooth but nothing like the two above .
