Handle: Very comfortable to hold the knife because the design of the handle. It has a tear drop design so it fits in your hand smoothly, and also it is just very attractive, in my opinion.
Blade: Comes very sharp out of the box, and maintains its sharpness for about a week and a half (based off of heavy usage). My knife came with a knife sharpener that was specially designed for this knife, although, I wouldn't recommend using it unless you've used a knife sharpener like the one provided before. The reason being is because this isn't a cheap knife, and when it came time to sharpening it, I used the sharpener it came with, and I ended up chipping the blade (thank Goodness for the lifetime warranty).
Performance: Performance wasn't bad. I definitely loved how smooth it was when I first got it, but I didn't enjoy it as much as I would have liked because I just prefer a larger belly of the knife, and this knife doesn't have much belly to it. So unfortunately, I find myself using my $15 knife a lot more often than this knife because of that.
Overall, though, it's a great knife, I recommend it to anyone looking to buy this knife. It's certainly the most beautiful knife I have ever encountered and am proud to own it. I think it definitely deserves more recognition, but you definitely won't be disappointed with this purchase.
