I've often wondered at the pony jack, I like the look of it, but there are others much higher on the list.
(But it would seem my surprise was not ungrounded, as your Pony Jack has yet to cross the 'carry' line? Lest my tone be misunderstood in text, I intend no snark in the question. I've learned for myself that the true test of a knife's "place" in my selection is not initial enthusiasm, but whether or not I carry it over and against other choices, over time. Plus, we do tend to remain true to ourselves, though it might take some working out to understand what that means.)
I agree Pertinux. I think the test of time is the best evidence of all. There are knives that I own that I was sure would be frequent pocket dwellers, but have not for whatever reason, lived up to my expectations.
Let's use GEC as an example; shortly after their release I bought a beautiful #92 eureka jack which ticked all the boxes for me, it should have been ideal. When it arrived it was beautiful and surprisingly for GEC, sharp out of the tube. A very pleasant snap to the blades, spear and coping (great combination of big slicing belly and small scalpel point), gorgeous coloured calico bone, and the eureka shape itself excellently done. I hardly ever carry it, I don't know why, it just doesn't work for me.
About a year before that, I bought a #61, purely because I didn't have a half congress pattern at all. It's a stupid shape, really, with a sheepfoot main which is very short, and a squat pen blade which doesn't have as much point as it should, and is too thick for comfortable slicing. I use it all the time, and it is probably my most carried GEC, and I don't know why. It just works for me. Over the last couple of years this has rekindled my congress affection and I carry them often, mostly this teal bone #61.
Strange isn't it.
