I think price and availability may have a factor also. Peanuts, 2 bladed jacks, sod busters, stockmen and trappers are all pretty available locally in most places and can be had for under 30$ to what ever price some one is willing to pay. Plus they are very utilitarian, and easy to pocket pluss you can still find all of them in synthetic, bone, or stag, and in carbon or stainless. so the materials and price have something to offer to every one. Muskrats, toothpicks, doctor knives, newer scout knives, folding hunters, fishing knives and others, are harder to find locally at least around my area, and seem to be more expensive with less materials available. combine that with the nostalgic stories we read and recommendations from here and I think that what gives them the hype.
