I have all 3 and was looking for opinions on them. The Pika II I just got yesterday, and I'm not sure about it yet. All three have solid lock up, with no blade play in any of them. All 3 will shave above the skin with a proper sharpening, and the Benchmade Pika II would do it out of the box. The others may have as well, but I dont remember. Fit and finish on the Cara Cara and Pika II are about the same and what you'd expect of $25 knives. The Delica is better in the this area. The other 2 have small visible gaps where they bolt/screw together. No problems, but the fit is a little less on the cheaper knives. The Delica carries easier, and is smaller by about an inch, than the other 2. The Pika and Cara Cara weigh about the same, and the Pika is slightly (1/16") longer than the Cara Cara when closed. With only one day of carry for the Pika, it seems to carry the same as the Cara Cara. The 3 feel good in hand, but the edge here goes to the Delica. The Cara Cara feels good with the textured G-10, and the Pika feels good in a saber and choke up grip. The hump on the handle in front of the pinkie is noticable and tends to guide my hand to a saber grip rather than a hammer grip, though this has posed no problems in the limited use so far. One thing I like about the Pika is the more pointed blade shape. The long clip point is more akin to the earlier, pointier Delicas than the Delica 4, which is the one I have. I prefer a pointier blade for a folder, since I frequently use them for removing splinters. My old Schrade Peanut has been retired from that duty for a while, so whatever folder I have will get pressed into service. This weekend while the wife is out of town, I'll try some edge holding tests on all this cardboard we have from the holidays. I wonder about the clip on the Pika, since it has only 2 screws, and a slot in the center that seems like it would be weaker. However, I do like the low carry fold over design, where the bend in the clip catches the pocket, rather than the area just in front of the screws, as on the Delica and Cara Cara.
