Both my peanuts are Cases…I bought them both after reading numerous posts on the Peanut Cult thread on this forum. They are the perfect 5th pocket knife, bar none.
What do you mainly use yours for? Since I work at a public school, mine are limited to opening envelopes or cutting the occasional box or string (traditional knives are usually frowned upon in a public school…a multi-tool or SAK is more accepted…the small size of the peanut is an exception). I live on an acreage, so I always have a knife with me outdoors. I find the peanuts a little undermanned except for cutting twine. Right now, I carry an older 3 1/4 " Kershaw lock back instead.
My favorite thing about the peanut is that the pattern reminds me of my grandfather's jack knives. His were a little bigger, but still the two bladed jack design.
