Looks like Boker is taking things a step further. Check out this blurb for one of their neck knives:

At Boker, we have always been committed to innovation. In the past one and a half decades, we opened up our Boker Plus brand for many new ideas without losing sight of our traditional values. With the Urd 2.0, we are taking yet another big step forward. Dirk Hofmeister founded Midgards-Messer in 2017, where he and his daughter did pioneering work. We partnered with him to present the Urd 2.0, much more than just a neck knife. Though the sturdy all-rounder is great fun and very useful in its original state, the greatest joy of the Boker Plus Urd 2.0 comes after the purchase.

Customers can download files of handle scales in various shapes and sizes, spacers, sheaths and gift boxes and print them in many different shapes, colors and materials on regular 3D printers.

Use it with a handle ring or as a three-finger knife, design it with various man-made materials, wood filament or glow-in-the-dark- materials. There is no limit to the design and playful experimentation- , drawing from a wealth of color- and material combinations. A range of different handle shapes also offer customization options based on your needs and preferences. This knife redefines the concept of modular design for the knife market.

Customers who don't have a 3D printer can use the Midgards-Messer print service to order customized handle scales based on their ideas. The Facebook page of Midgards offers plenty of inspiration and support. The Urd 2.0 comes with black G10 scales and a Kydex sheath with a ball chain, which means that the knife is fully functional even without a 3D printer at home. The sturdy blade is made from D2. Despite its compact construction, the Urd 2.0 offers a firm grip so that you will be able to tackle tasks that require more cutting force. We are very happy to offer this knife honoring our commitment to being an innovative knife manufacturer.
 
That's pretty cool actually.
But how does the knife look?

Not sure I care for the knife itself, but good on them for doing something different.
 
At some point soon you'll just buy the file for the whole knife and print it at home.

Given that 3D-printing steel is considerably more complex and costly than plastic-printing, it's pretty unlikely. And there are a number of reasons that 3D-printed steel would be inferior to traditional processes.

That's why I said "soon". Kids in elementary school are using 3d printers in shop class; the future is coming.

That said, there are a few different 3D deposition printer / sintering machines which can create fully functional knives from steel powder, including materials like D2, for instance. Terribly useful technology, also very expensive. With all that is possible with a machine like that, it is somewhat a waste to develop knives with it, IMO. Not like I'd let that stop me if I had access to one!

From what I understand, porosity of the finished objects isn't as much a concern as it once was with this type of technology.

Sintering machines do significantly reduce porosity compared to CNC welding-style additive manufacturing, but you still have a coarse surface finish and increased flexibility compared to machined goods, as well as greater susceptibility to fatigue stresses.
 
Definitely an innovating idea, although I do agree the knife itself could have been better. If they would do a simple 3” clip or drop point they’d sell a lot more.

I planned on getting a cheaper 3D printer with my return this year, thinking that whenever someone has a birthday or a wedding, I’ll print off a little statue in my likeness and give it to ‘em. It’d appease both my vanity and my frugalness, haha.

There are certainly still limitations! But it is exciting to see this type of tech develop over time.
