Givory is plastic. G10 is Fiber glass.

I'm sure someone will give a more detailed response.

Grivory is a 50% glass-filled Nylon-based plastic polymer. It's considered to be a "metal-replacement" material, meaning that some of its strength characteristics are comparable or superior to some metals. I believe aluminum is the closest comparison. It's injection molded in our applications.

If you really want to learn more, you can dig up an MSDS and a data sheet on the google machine.

Haha thanks to everyone

So would the good-better-best be Versaflex-Grivory-G10, or can't they be compared that way?

They can't really be compared like that... Haha.

Different uses for each material.

Is Versaflex kinda rubbery?

Too soft to make entire handle scales out of?

The only drawback of Grivory/Valox/Zytel (FRN) is that it tends to be a little slippery when wet. Is the idea of adding a Versaflex inlay to provide more grip?

As far as good better best, it would depend on your priorities. G-10 is pretty close to indestructible, but so is FRN. The only advantage G-10 has over FRN is melting temperature, as far as I know. The advantage of FRN is it can be molded into any ergonomic shape or texture. I've got a knife with molded Valox handle scales that you cannot tell from Anso grooved G-10 without scratching it. It's great stuff. I have a really hard time telling my G-10 and Valox Barrages apart.

People mostly complain about the hollow sounds the FRN handle scales make - that's 'cuz they are hollow...to save weight. But they are not much less durable. A G-10 handle scale won't melt as easy, but it is heavier...and more expensive. So good-better-best, I don't know...I would say Micarta-FRN-G-10, myself, but the difference between FRN and G-10 gets a little blurry depending on how you mold it, and how much you want to spend.

Have you had a chance to handle the 167/169? Those have Versaflex overmolded onto Grivory substrates, same as the 560/590. The Versaflex is rubber, essentially, so it's grippy and soft. It improves ergonomics and grip, while the Grivory provides the "exoskeleton" or structural component.

Versaflex would likely not work well for a folder handle by its lonesome.

I haven't had a chance to check out any of those yet. Sadly we don't have a dealer nearby. I think there's one on the way to my family's cottage - I'm going to find out and check that out when we re-open it in the spring. 781 is first on my list anyway.

Every time Jason gives his explanations of material makeups for knife handles and hints at looking up the MSDS and data sheets for further info, I always do. And I always find some interesting stuff in my searches. Anyone else doing this too? It gets pretty in depth, and you can learn a lot. I must not be the only one nerdy enough to follow through with further searching out info on knife materials, because there's obvious interest here from a decent number of guys who want to know exactly what it is they are holding in their hand when going ahead with a cutting task.

Also, Po, I've been meaning to put the bug in your ear (stop me if I have already) that you should definitely try out a Protagonist. I think you could chalk that one up to the 'awesome sauce' category. Give it a go, my friend.

Not per recommendation, but I have also looked further into the makeup of the materials. It interests me as well. Is it better or worse that I've done it on my own? lol.

Thanks, Marty. The Protagonist looks like a great knife to me, but just seems like too much overlap with my Nimravi. The big Nim is the inspiration for the overall design of the Protagonist, of course, and my Nim Cub has Grivory (Valox?) handle scales, which I think are brilliant. So I just feel like I've got Protagonist territory covered.

Speaking of my Nim Cub II...that's a perfect example of brilliant use of Grivory/Valox handle scales. I bought the Cub thinking of tossing the handle scales and using it as a skeleton handle neck knife. But the scales were so cool, and so virtually weightless, I kept them. I love that knife.
