I disagree with buying fakes.
At the same time I see a lot of "legal terms" being thrown around like IP theft. Patent stealing. Copyrights and Trademarks....
Before you use this term...you might want to look up what it actually means and what it's limits are.
Here's a short summary.
intellectual property
nounLAW
noun: intellectual property
intangible property that is the result of creativity, such as patents, copyrights, etc.
This is just an umbrella term. Please note...unless a design has been put down somewhere on paper or registered....it is NOT officially (legally) someone's Intellectual property.
copyright

"he issued a writ for breach of copyright"
a particular literary, artistic, or musical work that is covered by copyright.

verb
verb: copyright; 3rd person present: copyrights; past tense: copyrighted; past participle: copyrighted; gerund or present participle: copyrighting
1.
secure copyright for (material).
"copyrighted music downloaded illegally from the Internet"
looks like this could be applied to knife designs. However only if it's been registered. If nothing was ever officially registered as copyrighted...then this does not seem to apply.
patent

nt,ˈpeɪt(ə

nt
noun
1.
a government authority or licence conferring a right or title for a set period, especially the sole right to exclude others from making, using, or selling an invention.

"a company has since taken out a patent on the chemical"
adjective
1.
obtain a patent for (an invention).
"an invention is not your own until it is patented"
Once again....a patent has to be applied for and registered. And even then it's only applicable for a limited time.

a symbol, word, or words legally registered or established by use as representing a company or product.

a distinctive characteristic or object.

"long hair was the trademark of the hippy"
verb
verb: trademark; 3rd person present: trademarks; past tense: trademarked; past participle: trademarked; gerund or present participle: trademarking
1.
provide with a trademark.
"they are counterfeiting trademarked goods"
identify (a habit, quality, or way of life) as typical of someone.
"his trademarked grandiose style"
This shows that yes, you can have an unregistered trademark...however in order for it to be legally applicable it needs to be registered somewhere.
To my knowledge very few knife designs and features have actually been registered as intellectual property. There are a few yes. But most are not.
Are there any in this Shiro clone? I don't know.
I however suspect that the guys at Shirogorov (and several other companies) do not hold patents, trademarks or copyrights on Bearings....blade shapes....handle materials....milling patterns and even overal design.
Some might....but I suspect a lot don't.
As such it's highly unlikely that the companies copying those designs or features are actually doing something illegal.
Morally wrong? Maybe...but that's a whole different discussion. Especially when you're having that discussion concerning a completely different culture that's being raised to "Learn by copying the master" from the time they're infants.
TL,DR: Chances are that the copying companies are not doing anything illegal. And that morally from THEIR point of view they're not doing anything wrong.
Doesn't mean we have to like it though
