Of the three listed in OP:
Case , yellow handled, chrome vanadium (CV) Barehaead Slimline Trapper.
I am 53, and all my life this Slimline Trapper and the Case Peanut, also with CV , have been "my" knives.
Slimline pocket carries easy, is light, and is a proven workhorse by me, ranchers, farmers, timber folks and countless others.
Stockman is no longer made in YH with CV, it is a big knife and heavy.
Boker , MooreMaker and Hen&Rooster do still offer this 4" plus knife in Carbon steel.
Sodbuster, as the picture shows in comparison to the Slimline Trapper is big.
Sodbuster Jr, on the other hand is easier to pocket carry and will fool one as to how that knife carries so well
Again, I recommend the YH, with CV blades for the Sodbuster Jr.
I have nothing against other patterns, just for me, a Peanut and Slimline Trapper covers everything I need to do.
I have used these for weeks on end in the Wilderness such as in Canada, and canoeing and portaging, survival classes for a few days, to weeks, hunting, fishing, and down on the property doing farm, and ranch duties.
Slimline will handle whatever task needs doing.
