Emerson wave patten?

I'm in one of those places. Open carry only here. I just don't care what other people think. At one time, I EDC'd a ZT bayonet on a drop leg rig.

Unfortunately, I have to care what people think. I own a small business and open carrying a fixed blade would be a no no. I much prefer to carry fixed, but I'll wait until the business gets to the point where I can lounge in the sun, check the books, sign the checks and put out the occasional fire before I strap one on.
 
You should open a knife shop; then maybe you could wear it and expense it.

Some day. ;) As is, it's a dog grooming salon, which is happily thriving. And, while I hate to stereotype, I think I'm gonna make a few customers very uncomfortable if I'm hauling around an 8" blade on my hip. :D
 
Get a jumpmaster and tell them it's in case a dog gets tangled up in a leash and you have to cut it free.
 
Oh, and if you trademark something hoping to protect the utility of it? Yeah, you're the one abusing the system, no way around it. That explicitly not what trademarks are for.

And yet, the the USPTO still issued a trademark to E.Emerson for a patented design. I guess they like being abused.

They issues a trademark for appearance, not utility. Make a wave that looks like a dinosaur head or a big toe or whatever and you're fine. Heck, as previously pointed out, you could probably do fine just by omitting the jimping.

That would be horrible IMHO... ;)
 
Ernest Emerson is a fantastic knife designer and his knife formula is perfect, imo. That's all I care about.
And, he seems like a nice dude.

I agree man. And he is super nice. I was parked out front of the Emerson building waiting for a buddy to show up and he just walks up to my car and starts talking to me. I love the designs and since he worked on the designs with many special forces units I think his knives are built properly and to the specs the units wanted. I'm pretty sure the SAS uses the CQC8 still.

Here's an interesting derivative:

Patent or trademark infringement? Debatable if you go look at the Emerson patent. This is just a removable stick, after all. But, alas:

Protruding from the top of the blade's spine is a removable Emerson Opening feature.
The device popularized and patented by Ernest Emerson of Emerson Knives, functions by catching the back of a pant's pocket when drawing the knife, opening blade in the same motion.


It's about integrity and respecting other people's Intellectual Property.

Wait, are you claiming that someone using technology that had a now-expired patent is not respecting someone's intellectual property? If so I have some very bad news for you about, well, everything you own.
 
Spyderco licensed the feature from Emerson.

If you're smart you can even estimate how much it cost by comparing plain vs. wave Spydercos.

There's this little thing in the world that not many folks are aware of called "Mutual Respect" that helps agreements like this come into play.

You're forgiven if you've never experienced it.
 
The Wave patent isn't expired. :confused:

Yeah, but Spyderco licensed it for the model in question. I'm really and truly trying to get to what, exactly, the issue symphonyincminor is complaining about. My interpretation from earlier posts is that he thinks patents should be respected in perpetuity, which strikes me as deeply odd.

Side note, the model pictured would definitely violate Emerson's patent, but would in no way violate his trademark.

Considering that folks here get revved up about knives that look vaguely similar when there are absolutely no intellectual property rights and never were, it isn't surprising.

But I would assume that if he takes that stance the only liner locks he owns were made by Walker.

You mean Cattaraugus, right?

Patent # 825,093 issued on July 3, 1906

Walker popularized it. And you're sorta, kinda correct; the only liner locks currently in my collection are from Spyderco (who openly refers to it as a "Walker Linerlock" on their website) and Emerson (who credits Walker with inspiring him to get into custom knifemaking).

So if credit is given a person can wave & sell knives without repercussion or having to pay any royalties? Sweet deal.

No, I mean Walker. All the previous liner locks (there were others) relied on a slip joint spring spine to keep the knife closed. Walker combined those functions into a simpler, easier to open mechanism that is one of the main reasons you can flick open a blade so easily on today's knives. Walker set the bar to where other mechanisms needed to follow.

I owned a liner lock Cub Scout knife in the '70s. It was a much sillier way to lock a knife instead of simply using the spine to make a back lock. The Walker Linerlock is a great leap forward.
 
I'm guessing you take all the pocket clips off your non-Spyderco knives as well. Must make the wave harder to use, though.
