Manly Wasp. S90V for 65 EUR is very good deal, but a few years ago when they were available everywhere I couldn't decide because I disliked slipjoints. Now I want it, but they completely disappeared from local stores and I prefer to avoid international shipping.
Kershaw Junkyard Dog 2. I liked this quite unique composite blade, but back then I wasn't sure about spending that much for a knife.
Kershaw Skyline. Back then I thought a handle without 2 full steel liners can be a problem and before I changed my mind, bearings flippers with the same steel for the same or lower price already appeared.
Ontario Carter Prime. I liked it when I first saw the pictures and was waiting for my local stores to get it. It took so long that when they finally did, I already lost interest and moved on to other knives.
Rat 1/2 in D2. I don't know if they are all like that, but my country had only versions with coated blade or fake carbon fiber handle. I dislike both, but I was thinking maybe D2 is worth it. Before I could decide D2 became more common and I got other knives without any of these design flaws.
Kizer Feist. I read earlier models had quality problems that supposedly were later fixed, but since there was no different name, box or other way to easily identify improved series, I wasn't sure if I want to risk getting a bad one. And soon after I found Real Steel G5 to try a front flipper.
Spyderco Dragonfly / Delica. I still think about it, but probably won't get any of them. I want to get it for ZDP-189 steel, but every time I go to a knife store site, I can't decide because of plastic handle for that price.
