I grew up usingmostly stockman's because that's what my dad and uncle usually had and I thought it to be a good design-3 blades= 3 knives, very useful tool.
A few years ago I purchased 2 Case knives from a big retail knife store and one of them was a yello cv peanut. My gal saw it and said, "oh is this little one for me?"
I let it go at that, she carried it a little as she did with my tiny UH stockman and she keeps them in her jewelery box with her dad's 6375 XX and a couple baby butterbeans she bought for herself. Speed forward a couple years and I saw a great deal on a pocket worn red bone true sharp peanut as I really wanted to try one too for myself finally. I find it to be just as other peanut enthusiasts have.... just a very useful and carry friendly companion. Speaking of companion, I hadn't been captivated to carry one particular model as I always have more knives than I can wear out in a few lifetimes, but, I do have a Buck 309 companion that has the same qualities and useable characteristics as the peanut, only without the same thickness or the neat curves of the peanut. For me it's better than a pen knife (love those too)I like how they disappear in my pocket and just pop out when needed. A couple weeks ago I purchased yet another 3-7/8" yello Buck 301 and it is fun getting to know it and use it, but the peanut keeps getting in the way like a small child saying "me, me pick me"... it's just so darn perfect in size and has good handling and I love the small pen blade.
Some other useful jacks I have are an Old Timer 33OT that has almost the same going for it, and my Case 6244 that I dug out of a flea market for $2 is almost there too, but the peanut is still in it's own niche-kind of an enigma for me.... great experience and fun thread.
