Yeah, that's a Boker I'd buy (now dreads email from BladeOps et al :) )

To OP, there are any number of times where you are committed to something that cannot be let go of with the one arm, and that opens-with-one-press knife is the exact right thing to have.

And, I do have to admit to a bit of a Boker addiction.

My only one is a Boker as well. It was a gift and I considered it a novelty until I got to use it a couple times. Now I'm a believer.
 
The spring in my Blur broke, I replaced it in about 10 minutes.

It didn't change the operation of the knife, just wasn't assisted anymore.

So your ZT should be fine if the spring breaks.
 
the knife is as useful as a slip joint.

Ummm, the locks (liner or frame or even button) are not part of the opening mechanism so wouldn't be affected by a broken spring. Opened manually they lock like "normal" and have to be unlocked like "normal". Only difference is they don't spring to lock until you replace that busted spring.

(just a...) flipper lever
Stud, hole, lever, or hump on the blade base... I categorize all those as "assisted" opening rather than "automatic" opening.

Re definitions
In 2009, there was a federal effort to clearly define and limit the number of restrictions that could be placed on knives that were determined to be of the open-assist and one-hand-opening variety, as opposed to those categorized directly as switchblades. 15 US Code 1224 Exemption 5 states that:


“A knife that contains a spring, detent, or other mechanism designed to create a bias toward closure of the blade and that requires exertion applied to the blade by hand, wrist, or arm to overcome the bias toward closure to assist in opening the knife.”

In other words, this defines an assisted opener as a knife that is designed to remain closed until acted upon, whereas a switchblade could thus be assumed to be a knife that is biased to remain open unless retained.
 
Buy one--if you buy quality and don't mess it up, you can sell it and probably get nearly all your money back out of it if you decide it's not for you. Carry it for a week and see what you think.
But what do I gain from having one? Is having an auto opener or an assistant opener a necessity or an aesthetic?

I want to be really clear if somebody else wants an auto opener or an assisted opener great. I have no problem with that.

I just don't see what I'm gaining from having one. I had a CRKT igniter assisted opener and it was more of a pain in the ass then it was worth.

I like the Benchmade Freak but I could never bring myself to buy one (Assuming SWMBO we'll even authorize the purchase) because I just couldn't come up with a single application in my life where an assisted opener would be necessary. Cool to have? Sure but not necessary.

I'm not trying to criticize other people's choice of an assisted opener or an auto opener.

I started this discussion hoping that somebody could explain to me what makes an assisted opener or an auto opener necessary.


I know this is going to sound insulting before I say it but that's not my intent. One thing I noticed is it nobody that's responded to this discussion has been able to say well my assistant opener or my auto opener was useful for this specific function and that's why I bought it.

I'm going to ask you a silly sounding question, but bear with me. What are you calling an "assisted opener"? A knife with a flipper fin?
No I'm talking about something like a Benchmade Freek


Or a CRKT Ignitor


I'm not saying you shouldn't have one. I'm just wondering if there was something I missed when I decided I have no use for one

I always advise finding out for oneself when you're sure something isn't going to be to your liking without having experienced it. I guess that makes me an enabler, but in a positive sense. ;-)

My points are still the same. The mechanism adds a bit of safety, it can be useful if your hands are stiff or lack dexterity due to age, infirmity, or gloves, and it doesn't detract anything if it fails. The flipper versions are the handiest in my thinking (and that's in spite of the fact that the original Ken Onion Random Task is one of my favorite AOs).

You will find out if you gain something or not by using one for a few days.

Of course it's not necessary to have an auto or an assisted opening knife--it's not even necessary to have a folding knife. People got by with fixed blades for a very long time before folders were invented.

I'm not sure what you mean by 'an aesthetic'. I've seen knives in all forms that I considered very handsome--including some assisted openers and autos.
I had a CRKT igniter assisted opener and it was more of a pain in the ass then it was worth.
The way the OP was worded, it sounded like you had never had one. If you've had one and you didn't think it gained you anything then I would say you've already found out that it didn't gain you anything.
I just couldn't come up with a single application in my life where an assisted opener would be necessary...
I guess I'm not really following. Did someone tell you that AOs or autos are necessary? Who told you that? I would ask them why they believe such a thing.

That's an answer that makes sense to me.
Thank you.
 
1. On principle I believe a person should be able to buy a Light Saber (assuming they ever exst)if that's what you want.

I also believe that an auto/assisted opener is just one more moving part to break.  I don't see any practical use for one and it's highly unlikely that I will ever buy one.

My question is "Is there something I'm missing?" "Is there a practical reason to pick an assisted opener over a similar knife that isn't an assisted opener?"

Say for instance a Benchmade Barrage V. A Griptilian.

What advantage does the assisted opener give me?

The question you ask comes across kinda off-kilter to me, as if this method might be considered "wrong".

The point of this is to "assist" in opening the knife one handed. As you, and others, have stated, there are more than one way to do this.

There are advantages and disadvantages to each particular method. Some will be better suited under certain circumstances, and many are well suited for a diverse set of circumstances.

And let's not forget simple preference, because that's important as well.

I can open my three bladed Old Timer with one hand...but that involves a bit of digital dexterity, a smidgen of time, and a potential compromise on safety when handling a sharp tool. I have a greater chance of cutting myself this way than opening via a normal two handed means. And certainly more so that I would with a knife designed to be opened one-handed. Plus there's a greater than zero chance I could fumble and drop it in the process.

The whole point of a folding knife in the first place is to be able to safely and conveniently carry around a bladed tool in a more compact form, in a safe condition, but which can be readily deployed for some task at hand. This, in itself, offers many advantages...but at a compromise in knife strength and durability.

Likewise, the many means of opening provide options which people can pick and choose from to best suit their needs and desires.
 
I have two "high dollar" knives, (I put high dollar in quotes because I know people here carry knives worth about what my car cost - :) ), and I really am not familiar with the term, "assisted opening". My first is a Benchmade Resistor, which was a gift. It just has the thumb stud, assuming that is not "assisted opening"?

Now this one I found. Seriously. It has seen some hard use and it went back to Benchmade for fluff and buff, and is a great knife. This is what everyone here calls an "automatic knife" because the term switchblade comes loaded with "bade vibes, man". Benchmade Auto Stryker.

Which one rides with me? The Resistor. Why? The dadgum spring clip on the Auto Stryker is WAY too tight, very difficult to slide it on anything. But both are equally functional. And free. Hard to beat free.
 
In my understanding an auto opener is basically a switchblade.

An assisted opener is a knife where you have to start opening the blade and then a spring takes over and snaps it open.

From Wikipedia
An assisted-opening knife is a type of folding knife which uses an internal mechanism to finish the opening of the blade once the user has partially opened it using a flipper or thumbstud attached to the blade.


As I said in my opening post I see it as one more moving part to break. It's highly unlikely that I would ever buy one.

I don't care if you do. I don't care if you buy one just because you think it's cool. as far as I'm concerned that's a valid reason for you to spend your money on it.

The only reason I asked this question is because I thought there might be something I was missing in the equation.

What you are missing is the ability to use the knife. having only one hand available.
If you are always going to carrying a fixed/long blade, no problem.
 
One hand is good so long as the blade can be operated the way you like be that auto, assisted or manual. Some of the autos I dislike due to the force of their opening and abrupt stop. Current ones are made to take that pounding though I've seen some loosen up due to this. I look at the cutlure of some users that fling their knives open and see it like flinging the revolver cylinder closed. Then in a year they are complaining how the knife doesn't open-close the same.

I still like the manual liner or Benchmade "Axis" type lock. More challenging to be discreet with an auto and assisted variants without using two hands to slow the blade opening.

He has one hand openers with thumb studs so he already has the ability to open the blade with only one hand available.

The question was whether he was missing some benefit of assists or autos vs his concern over the more complex mechanism.

i gather his concern is the spring that might break in assisted openers or switchblades causing some problem with use, but we've explained a broken spring won't interfere with opening the knife (at least not in the fin, stud, or disc equipped ones).

Night Rider can correct any of that if I've gotten it wrong, but that's my summary of the points.
 
I own a Barrage and a Violi. Lost a mini barrage somewhere in the yard. I find AO handy indeed. I've owned the referenced AO knives for a lot of years and they've definitely seen a lot of use. Not a single problem ever. The nicest thing about AO is how fast and positive they open with either hand, gloves, awkward spot, you name it. One handed close goes without saying. Certainly not restricted to AO knives though. Axis lock is great in that role.
