Is "flinging" a folder open with inertia abusing it?

I've got a 12 yo Delica that has been flicked open 10 of thousands of times and it is no worse for wear. Its not like dry firing a Glock ( broken breach face).

Perhaps because the blade has so little mass?
A light blade produces less force and deformation; the knives I screwed up had fairly massive blades(especially compared with a Delica:)).
 
a large blade is harder on the lock if ya inertia open them, a rekat SIFU w/the 5.5" blade would break the lock about every other time ya inertia opened it, of course the rolling lock hardly needed to be abused to have problems, a very poor design imho (lock of the 21st century my rear end lol).

as far as a cuda maxx i inertia'd mine lots with no probs, and darrel ralph (the designer) says all his CUSTOMS are plenty strong to shrug off inertia openings, i have had probs with the stops coming loose on both the cammilus and ths custom versions of the maxx, but a little loctite fixed that right up.

sometimes it would & sometimes it wouldnt it depends on the scenario, its certainly an option i wanna have available to me if i should need it. as far as being fsater/slower that just depends.

same thing with waving a knife open, some scenarios wont allow ya to wave it, some will,

ya lost me on speaking text message though, WTF are you speaking of??

Well, since you asked me. I don't usually read posts where the poster has taken as little effort as you, and others, to express a few thoughts. Because I do a lot of reading, posts like yours with little to no capitalization, run on sentences, lazy spelling mistakes, and little regard for punctuation are just too hard to read, so I don't. I see this mostly from the crowd who "text message" a lot – an effort to economize thumb movement perhaps. I sometimes wonder if it is the "text message" syndrome or if English is not a person's primary language. ...and I don't particularly like to be sworn at, even if it is an abbreviation (WTF).

Back to the topic, can you identify a set of circumstances where flicking your blade open is quicker than just using the tumbstud or hole? One can use the opening feature while removing the knife from the pocket. Any other movements, dramatic or not, just seem to be wasted.
 
Knife clipped inside front pocket. I grab it use thumb stud to open. How is "inertia opening" faster?

How would I inertia open it?

It seems like to flick a knife open I would have to take a pinch type grip on the handle and then I would have to flick it and then readjust my grip to hold the knife normally. It seems like that would take more time than opening it as designed.
 
Don't many knuts flick their knives just for the effect? And then there's that resounding Click, when the blade locks. ME?---No flicking.

ohhhhh so sorry i didnt know this was english comp 1.

sure i can come up w/a scenario or 2 but since i dont have my copy of english as a second language handy i better refrain lol.


oh by the way bruce, would spelling "thumbstud" as "tumbstud" be a lazy spelling mistake??? just wondering..........i'm not familiar with a "tumbstud" FWIW??

i just LOVE IT when folks criticize others then make the same mistakes, lol, lol, oh my i am LMAO.

if i had a nickle for every one who posts criticisms of other folks spelling/etc, then has a miss-spell or something in that very same post, i could buy a knife, you would think folks who do that would be a little more carefull in that post, but they never are, happens almost every single time, lol.

thanks bruce, i was in kinda a funk this AM, i needed a laugh, thank you very much, sir.
 
With the 'Spydie Flick' I can get the handle to just glide into place and snap it in for good lock up with the last little snap of the swing. My old Gerber 'Bolt Action' lock utility knife would 'swing' out when you released the bolt but you had to time the re-engagement of the bolt to catch the blade when it was fully open or it would bounce back or if you let off to soon it would stop short. I think 'cracking' one into place with a quick powerful wrist snap has to be detrimental over the lifetime of a knife. Your term 'flinging' sounds less damaging than 'snapping' a blade open so somewhere in there the amount of force and control cross the line from acceptable to excessive force.
 
Just as a side note, in almost all the 50 states, a knife that can be flicked open is considered a gravity knife or switchblade by definition. This is the FEDERAL defintion of a switchblade :(b) The term ''switchblade knife'' means any knife having a blade
which opens automatically -
(1) by hand pressure applied to a button or other device in the
handle of the knife, or
(2) by operation of inertia, gravity, or both.

The reason I post this is the following: flick it open in a Post office or other Federal Controlled area and it is illegal, so forget about the wear to the blade....lol

I do think most liner locks and lock backs are worn down by flicking them open as I had done that for years growing up in NYC in the 1970s< and it did wear down the locks on all those knives for sure !!!!
 
i would imagine opening any knife in a post office is gonna raise eyebrows FWIW..........

if your definition is correct why arent all knives that can be inertia'd tightly controlled like a auto knife(ie the shipping laws)?? IIRC its because the definition is a little more entailed than that & because most knives dont actually fit the definition, IIRC. i think i have seen this argued out before FWIW.

It isn't an english class, and I make mistakes also. Yes, it was a lazy spelling mistake. If you look closer, you'll notice I also made some mistakes in grammar. I have a tendency to change "tense" in mid-sentence. But at least I try. In my job, I have to do "technical writing", write laboratory experimental designs and evaluations, prepare material for refereed journals, and comunicate with process operators through vice-presidents. I won't apologize for starting as a kid from a poor family and fighting my up through a graduate degree. ...and I won't apologize for believing that we should try to improve our situation and not allow others to "dumb" us down.

Now, a question. Do you know of any serious self defense techniques that teach "flicking" as an appropriate, and "best use" method for deploying a folding knife?
 
Speaking of which, the knife I own that seems to lend itself to and almost begs to be opened this way is a cold steel grande vaquero. No damage detected yet on mine in 8+ years.

I've owned a (used ) Grand Vaquero for 6 years now, never a problem yet, and almost always opened that way.

LOL! I know what you mean!
All my friends knew how to open that way and also to use "chucks"
did you use those old "007 knives"?
 
SIFU1A I am just qouting the law. It is not often enforced on the Federal Level, but it does exist. In NY, the gravity knife (flicking open) will quickly get you arrested.

wow no fooling, i minored in tech writing FWIW,I dropped outta high school myself in '74, then got my GED, then the military, then on to associates, BS and MS so perhaps you arent the only person in this old world to try and better themselves, i dont worry too much about about grammer & such when posting on the net, i guess to be honest i just dont care lol, i dont really see what difference it makes if the parties reading it get my drift, and that doesnt seem to be a problem. but thats just me.

and yes i know several serious techniques involving "flicking".

ooops i doubled that, how did i do that lol?????
 
Haven't read the whole thread but to answer the original question........

Two bits of metal hitting against each other hard and fast is never going to lead to anything good.

I say don't do it unless you have to, or get yourself a cheap beater that you can flick to your hearts content and then chuck it away when it shows signs of damage (because you won't / shouldn't trust it after that)
 
I have several ZT 300 series knives a ZT 0400 and several Blurs. All these knives are equipped with assisted opening. I just assumed it was all right to use this feature. I would think they would design the knife to be used this way, no? In fact the only way to open them without using the assisted opening feature would be to use two hands as at a certain point the torsion bar just takes over. What do you guys think? I'll tell you on the ZT 0300s it's the thumb stud that takes the impact and it looks real tough. Everything about those knives seems super tough. Please tell me your opinions.
