In what areas specifically have your neck knives helped you out? That's what I'm most curious about because the Eldris would be new territory for me. If I think about how I've used small blades before, I can come up with some examples. But since the Eldris blade is basically a chopped down full width blade, I'm eager to learn where it fits in from a survival/hiking standpoint. The fire starter option is clearly one example.
If I am working on multiple things at once, like say, camp kitchen food prep as well as getting a fire going, it's useful to have multiple knives. In specific, on my last campout, I had a folder (CS Ultimate Hunter if I recall correctly), an Izula II around my neck, and my Rodent 9. I had been using the UH to cut up some chicken for a dutch oven stew I was preparing for the group. Then I needed to open a couple packages, and chop up some veggies, so I was able to quickly set my UH down, pull the Izula II and dice up some potatoes, carrots, and peppers without having to stop to thoroughly wash/clean my UH (I did that later). The stew turned out great, and I was able to prep it all quickly because I had the two knives.
Also, I've camped a few times in the very short winter we get here, and being cold, I was wearing a coat and gloves. Having various cutting tasks, fire prep, food prep, whittling, etc. was a lot easier with a fixed blade hanging around my neck (in this case it was one of my customs) than in trying to get a folder out of a pocket, or to have to hitch up the tail of my coat to get at a belted fixed blade.
I have even had situations where I was doing something by the fire (whittling, firesticks, etc.), and was called to come help one of my group, so I set everything down and come over to help, and a cutting need pops up. So, I just yank the knife out of its sheath hanging 'round my neck, and I was good to go. It's just nice to have options, and I expect this Eldris will be a great small, light one. I'll be getting one for sure.
