Folding knife breaks

Reading through with it translated was funny because occasional words weren't recognized.

That said, this is why a folder is used for EDC, and fixed blades are used for hard use. It doesn't matter how strong the folder is built, a well designed fixed blade will ALWAYS be stronger.

Especially if it has a dohickey. :p
 
Looks like the knife fell apart exactly like I thought it would. Washers to blade tang clearance created the space needed to turn blade tang into a lever that pried the knife

apart. Duh.... The G10 compressed, liners deform, pivot pin breaks, simple ! Looks like he needed to do more with the only knife he had at the time. Probably not just a video

on how to make kindling from a 2x4 in your back yard. Idk....a dohickey might have helped.
 
Why in the world are you giving us that link ???

You think we've never seen broken knives before:confused:

And you could've found one from here at least. They've been many fixed blades broken here as well.

I don't get it.
I guess you're still trying to push the knife you've designed.
You will never convince us a problem exist that doesn't.
 
Interesting pics though...?

Ummm... No. They're really not.

Since the only example of this "problem" you've dug up is 15 years old (and it happened in another country), I would say it's not even a small issue.

We've been to this rodeo before, so I'll just say it now so I don't have to post it later... This doesn't prove why anyone needs the FFK... Sorry, I know... We aren't talking about the FFK- until you bring it up later in the thread and tell us all how the FFK would have avoided this "issue". Test your design alongside other designs, then come back and tell us what happened. Don't waste our time with posts that are 15 years old.
 
Tough crowd man. He really isn't selling anything as his knife isn't for sale yet. I don't understand why people are getting their panties in a bunch. How many knives have you designed?

Mostly because he starts thread after thread after thread on the same subject or manages to cause it to migrate to the same point. Just folks getting tired of it. He would find a much more forgiving crowd if he would just comment on a few threads honestly about whatever subject in it. Instead its a feeling of oh good grief here we go again.
 
cricketdave,
I have made comments on other threads. Every person has an interest or two . It's to be expected that people start threads on what interests them.

The thread topic is very clear...."Folding knife breaks". If you don't like it then simply scroll past and pick a topic that your interested in.
 
Yep thats the charming attitude I expected and also why you get very few serious comments or actual interest.
 
A knife that fails under abusive lateral strain is a safety feature, imo: glad to know the knife will break before my arm does... ;)

The knife in question is a Buck/Strider 880SP and it is built like a tank. I just can't imagine what was done to it to cause such damage.

I don't know about the built like a tank. By today's standards for overbuilt folders, the hardware is pretty skimpy looking.
 
Opinel. Generally the blade will break before the pivot does when you apply lots of lateral stress.

Don't try closing stress. The lock isn't made for that.

But laterally, the joint is much tougher than the blade.

The Opinel locking ring is a pretty fantastic design. It would be interesting to see it used with a beefed up blade, pivot pin, harder handle material, and maybe thicker Ti hardware. I would bet that it'd beat out a fair number of more complicated and finicky designs for strength. Of course the change for the lock material would require a completely different method of manufacture so I doubt it'd happen.
 
FFK,
I understand that you’ve come up with a locking mechanism that you believe in. And you have apparently gone to a lot of trouble to patent it, and work out the kinks. That is good for you, innovation and creativity is good for the knife world.

But if you want to market and sell your knives, you need to realize that people often buy the maker just as much as the knife. Obviously, the quality needs to be there, but assuming it is, you need to present yourself professionally on the forums. I don’t know you, and maybe you feel you are, but it seems pretty apparent that people are getting burnt out on these threads about your knife. You’ve proclaimed everything about this knife you can, I believe. Time for the rubber to meet the road.

You need to do some tests, preferably videotaped live, so no accusations are made about doctoring it. Even if the tests aren’t to destruction, show what this mechanism is capable of. What it can do that other knives/mechanisms can’t. That is what will be convincing. If you look back at Bladeforums history, tons of people have come on here making extravagant claims about knives. To set yourself apart, you need to show proof. Not talk about proof, not allude to proof, not extemporize or pontificate about proof, SHOW PROOF.

You face the additional problem of possibly inventing a solution to a problem that practically speaking, doesn’t exist. So far, you’ve shown one (1) failure of a folding knife that was laterally stressed. One which came from a much, much smaller market than the U.S. You haven’t shown one failure that is familiar to us here. That doesn’t mean they don’t exist, but it certainly doesn’t seem to be a common issue.

People keep telling you that most responsible people aren’t going to subject their folding knives to the type of lateral stresses your lock is designed to withstand, and you don’t want to hear it. Listen: That is your market telling you they don’t want your product in its’ current incarnation. Force feeding a product to consumers doesn’t usually work. Not to start on the seemingly inconvenient deployment process for the lock.

I hope some of this helps you out. If you don’t lay off the incessant threads and snarky replies, you won’t be able to give these things away once they’re finally ready for market. When will that be? Another good point, give your potential customers a target release date.

Sam :thumbup:

PS: Since you mentioned the thread title to my friend Cricketdave, as of this point, it should be amended to Folding Knife Break, not Breaks. Unless I missed one somewhere.
 
Tough crowd man. He really isn't selling anything as his knife isn't for sale yet. I don't understand why people are getting their panties in a bunch. How many knives have you designed?

And he keeps pointing at a non-existing problem that he has the solution to, and yet the only proof he has of this "solution" is telling us that his computer program says his knife is probably better at being a pry bar than other knives, but he hasn't tested those either.

Until he starts showing actual test results and actual physical models to back up the claims of his one-sided sharpened wonderbar, all he is doing is trolling.

As for that abortion that he called a "prototype" in past threads, he never really did explain why the "prototype" that was specifically designed to handle lateral stress also had a blade the same thickness as an Opinel...and he never explained why this rough and tumble $6000 "prototype" was painted and finished like it was ready for market.

Five.
Three of them were good. :)
 
Sam Wilson....."Folding knife breaks" some slang, I admit. Idk....maybe "Folding knife falls apart" would have been more accurate. I thought it was interesting that a folding

knife would break like that. I am happy that some made comments on the topic of the thread. Seems like bolsters are a must for increasing lateral strength.

Also a flexible HT..56-58RC. You and others keep bringing up my FFK, and yes the FEA results are very impressive, and yes I understand why they mean nothing to those who

comment negatively. How about a design suggestion or two on how you would prevent what happened to the "Folding knife that fell apart".
