I'd heard a lot about Civivi, and had experience with WE Knives, owning the Deacon and the Massdrop Gent Select. However, I was not prepared for how awesome the little McKenna is. The Damascus is gorgeous and perfect, the action is amazing, perfect detent. One of the best out of box experiences I've had. Thus far the 9Cr based Damascus is good edge retention, though the size of the knife does not dictate heavy duty use.
I've purchased a lot of knives off of the exchange. Spyderco Manix 2 foliage green CTS-XHP was probably the BEST I've purchased off of the exchange. The steel spoiled me. I love XHP. The ergonomics, style, etc made it the first knife I customized. I'm actually carrying it today for Manix Monday.
Now, here is an interesting twist on this topic and the topic of most disappointing.
The first Spyderco Southard I bought I was very disappointed with. Probably did not give it enough of a chance. For years I hemmed and hawed over whether I should give it another chance. I still hadn't made a decision and then it was discontinued. THis past March while perusing the forums, one came up for sale with a custom scale. I decided to try again, knowing I could sell it no problem. Well, its fantastic. I really really like it. Going from extreme disappointment six years prior to elation made it even more sweet.
