Tri-Ad Rip-Off?

I like the knife but can't help but wonder what the US retail will be. Especially considering that it sports Sandvik 14C28N blade steel.
 
It's kind of like the stg44 and the ak47. Whatever inspiration they had they won't admit.
 
Stop pin between the blade tang and lock bar. IMO it's a blatant patent violation no question about it. CRK better have a deal with Cold Steel or the cease and desist followed by a big azz law suit is coming quick. And in this case I would not blame Cold Steel one bit.

There is a degree of similarity, except the new spring design is better. Doesn't look like an issue that can be settled on this forum.
Probably best to take both designs down to Lennys' meat dungeon and get the boys a whackin.

One thing to note is that patent law is territorial. A patent needs to be filed in every country you seek protection from.

I'm not doubting what you're saying but didn't the US have to pay Germany (a country it was at war with at the time) royalties for the production of the Springfield rifle because it was a rip off of the mauser? How does that work?

its possible that the patent was filed in both Germany and the united states. Its common for large corporations and companies to seek patent protection in all territories in which their products will be seeking distribution. I don't know the particulars of that deal and its possible the laws have changed since then.

They are not CRK knives.
CRK is hosting these knives on their website to help a friend of the company get some public notice.
 
I'm not the one to cry on CS shoulder.They should take comfort in the Golden Eye,if they fell someone has wronged them...

That makes sense. I did not see CRK making something like this. Still that being said, the stop pin location makes these knives a blatant copy of the most important and absolutely unique feature of the Triad lock. I have little doubt if any quantity of these are sold in the US Cold Steel will put a stop to it.
 
The retail price will probably stop it before Cold steel ever could.

Plus, no pocket clip. That could kill it.
 
I don't think the locking mechanism is enough like the Tri-Ad to be a legal issue and the price I think is off putting to most as well making this knife a non-threat to CS anyhow.
 
I don't think it's a patent rip off. The triad lock is self adjusting due to a slightly oval shaped pivot pin hole in the lock bar as well as the shape of the blade locking cutout (deep and slightly hooked.) As a result this lock will not have as long of a life span nor be as strong. It will have the same wear pattern, for the most part, as any regular non-triad design lock back.

Again the triad lock is not a simple lock back knife with a stop pin stuck in it. It is not as simple as it looks at a first brief glance.

This is basically a lock back that uses a stop pin. This method is probably more expensive to manufacture but it does prevent the blade from buckling backwards when a lot of force it applied while cutting. The stop pin can also prevent lock rock in the backwards direction due to imprecise manufacturing, common problems on a lot of lock back knives. Most manufacturers settle for a precision lock bar to blade setup and figure it's good enough.

The Klecker lock uses the same principle without an actual stop pin or lock bar pivot pin and the newer Tighe Nirk folders (real Klecker design principles not just in looks) use an actual round stop pin. The Klecker except for the blade pivot uses zero pivot pins and I would argue that because of this it is a great knife for filthy, gritty, and/or salt air (with the right kind of stainless) conditions. You don't see Klecker suing Cold Steel for using a stop pin because it happens to be one necessary element in their design system. Push button locks and automatics as well as axis lock knives and likely others I don't know about all use blade stop pins. This is not a new principle and using a stop pin on a lock back it does not make it a triad lock.

No this does not share the same design principles of the triad lock even if they chose to use a standard lock bar setup instead of a spring integrated into the lock bar. Lock bar springs are simple, common, inexpensive, easy to manufacture and change if they wear out or break. This integrated spring lock bar setup is very proprietary and requires precision manufacturing because it is also the locking bar which is why I would prefer a standard lock bar set up.
