I prefer the Pen over the Peanut.
The Pen is a fantastic pocket carry yet the main blade is well up to a range of tasks. Fruit cutting is better with a Pen than a Peanut. Then, I like single spring knives, it's a demanding thing to get 2 blades to close&snap properly on the one spring. I have two CASE Pens, one cv the other ss and I can certainly recommend them. I just wish CASE would offer some different scales on the Pen, nothing rong with yellow mind, but Red Bone,Chestnut,Antique, would all look well on the knife:thumbup:
Böker do Pen knives but they are smaller than the CASE and not so useful in my experience. Other single springs you might like to consider for the future: Queen Muskrat, Norfolk pattern,certain Canoes,Half Whittlers and Half Congress,plus others. Good luck.
