I gotta say, this is a really neat little knife. I had to tap on it a bit to get the wobble out of the clip blade, so it doesn't have the walk it did before, but it's all good. I know it was there, and since I'm the one who took it out, it's ok. I'm letting this one get a patina on it's own. I was reading a post on another forum the other day that got me thinking. I carry a Leatherman Wave on my belt at all times. Not only has it saved the day more times then I can remember, it was a gift from my wife when we started dating, so it not only has functional value to me, but also sentimental value. I'll probably be buried with it when I go. Anyway, there was a thread about rust on Leatherman tools, and how they have a bad reputation for it. However, the rust is very superficial, and can usually be wiped away using nothing but your dry finger. Besides, ANY tool develops rust on it, without reducing functionality. I thought about this with my CV blades. I'm letting my Case Pen knife get a patina on it's own. No vinegar or anything. If a little rust develops, I'll wipe it off right away and go on about my business. I'm still new to the carbon game, but I have noticed that when I put a deep dark patina on my knives, they start to rust. Isn't this the exact opposite of what's supposed to happen? Maybe I'm just doing something wrong (leaving it in the vinegar too long?) Also, my soddie has started some slight pitting. Anyway, I'm letting mother nature take it's course with this knife. I've been cutting pears with it, and after just three days it's already completely dark, but there is still a slight bit of shine to the blades. I guess it's not completely sealed yet. However, it's been in the 90s here in Florida, and I've been sweating pretty heavily at work, and the rust has yet to make itself kniwn, so maybe this one will work out for me.
