I like that Moore Maker, but I have not really used it - haven't had it too long. It's less pocket friendly than that jack is. I generally pack an old case folding hunter when we go off to the camp, and I figure I will pack that one next time instead. I like the little sheath it comes with.
The red trapper in that picture is a brand new kissing cranes - pretty inexpensive. I bought it because I have a black one just like it that I carry and use a lot. It's a good value knife.
I have two moore makers on the way - one is an even end trapper and the other a moose. Their moose looks like a sowbelly trapper with the blades on opposite ends. I tend to accumulate out of the ordinary trappers, not really on purpose, but because I can hardly ever find, much less afford the one I really want - which is a 1965-1969 case stag handle one (it's what my Dad carried when I was a kid). So I get on there looking for one, and I generally find about one, and 29 wealthy people want it way more than me, so I end up seeing a good deal on another cool looking trapper, and so I have a large variety of not-your-everyday-trappers.
In fact I bought that jack because.. I had been eyeing it... I got a fairly good deal on that one, and it sorta resembles a trapper. I think of it as a city slicker's trapper... well suited for skinning those annoying clamshell packages.
