3d printable wave mod

Looks very Effective, How robust will the plastic be with regular use?

I have no personal experience with 3D printer plastic, honest question.

I am sure though, a similar design CNCd out of Aluminum with a screw fastener would be plenty strong.

Not very, unfortunately. 3D printer plastic becomes progressively more brittle over time. As neat an idea as this is, I think a thick leather one would be more durable if you'r looking at a snap as a fastener. My $0.02.
 
It needs a slip clip to squeeze it or a screw through it to tighten it in but it is the same basic principle as those we used when Spyderco first hit the market in the 80s. I remember because I was a young airman in the service at Scott working in the Oral Surg. clinic watching the ER techs flip off these blades open off their pockets. I of course had to check it out and they had these bright stainless knives that had big holes in the blades! They wrapped para cord and another one had some contraption of rubber tubing he fixed in the hole both so they'd whip the blades open. Both these had pocket clips but neither were being used.. It was like they didn't quite get it yet that it went on the pocket I guess or it could but it probably was cause they were tip down carry. Anyway, that was the first waves I knew of and I know it was at shows cause I saw it later and that is where the guys with the knives told me they learned about it because the Spyderco guy selling the knives showed that to them with his own knife! That was at Fairview Heights in Illinois right off I64 there at the mall exit where they always had a flea market up on the way toward O'Fallon and I was there all the time and somehow missed those bright shiny things! Needless to say I had my first Worker shortly after that and was doing some pocket ripping too and others did that as I've seen others post about it. Honestly I was surprised Spyderco didn't have something patented for a device of this type long before Emerson knives existed. Of course the quillion was the first but so long as Spyderco can come up with a device to work they can patent another one. Its the device that is the patented part, not the process of opening it off the pocket and not the idea. Abstract ideas cannot be patented. A new device could be though and be perfectly legit.

I would put a rounded but textured edge where your thumb will contact the wave when manual opening

Yeah I can see that working. Someone could patent that themselves and just name it clever. Something like, the Spiderclaw or Spydiehook or any number of names relating to what it works on. I would imagine being the material it is you could easily market it as the 'kindest to pockets' and only available for Round, Byrd or select other shapes for opening holes but you could probably mold that to fit thumb studs and over thumb plates as snap on attachments also as a SFO. Okay okay, my own experience of late has me still off in fantasy land but you get the idea. Why wait for Spdyerco just do it and start selling them.
 
Sorry if this has been covered, I admittedly didn't read the whole thread...

You would need to custom make these for each model since all the holes, material left around the hole, and thickness of the blade are all different on each model.

Cool idea though.

I was waiting for someone to point this out. I'm not much into waved knives but this looks like a fun project. Maybe screwed together with spacers is an adaptable idea.
 
You have a good point there , i think if the concept worked the numbers and values could be re tweeked for any knife
With a hole . The beauty of printing is the lack of re tooling .
Ive based this deign on the tenacious being so popular , im kinda hopeful it might fit on other modles ?
 
As far as I know all the printer plastic is the same and has a tendency to become brittle with time. Idk that for a fact though. It's my dad's word on it, as he does 3D printing at his job, but I have no first-hand experience, so fwiw...
 
right now I'm using a zip tie backed but black wax rope. it's a little loose but I heated it up before putting it on so it's holding fine. it's been on for months and waved a couple dozen times
 
looks like there are sturdy industrial choices as far as plastic goes , there are even some metal technologies out there .
heck i just heard the japanese have printed a liver from actual living cells .
i rustled up a sketch that would fit on the military 2 also suggested a couple of screw locations for some T6's .

Sazbo has a very round part there , looks like it would have
To be longer for that knife . So it wouldnt slip back ?
Looks like every case is different .
Dang what an awesome grind !

I think I recall seeing something like this made out of kydex or a similar material. I'll search and post back.

Could have sworn it was on one of the craftsmen's home pages but I couldn't find anything.

Looking forward to seeing the finished product though.

I've seen this in ebay!!!
 
So it's not an Emerson Wave, cause it's slightly different? Is that like the companies that have opening ovals instead of Spyderco holes? :(

It's not an Emerson wave because it isn't an Emerson wave and a Collins bolt lock isn't an axis lock and an axis lock isn't a CBBL lock.

Don't feel bad for Emerson, he patented his wave, before Emerson "knives that caught on clothing to open the blade" had already been around for decades.

I'm all for innovation and invention, maybe this design will be cost effective, maybe it will be available to the public, maybe the inventor will make some money.

Seeing this made me think of my own design for a pocket opening device make of steel, clamped on both sides allows holes to line up and a steel pin gets inserted to hold it together... Not that it makes sense without illustrations and not that it would be practical, BUT it would not be an Emerson Wave. :)

I don't know why you couldn't put them to a DXfile and have them laser or waterjet cut out for you from titanium, or aluminum or G10 or Carbon Fiber for that matter.
