Hey I own this knife now. Let me tell you what I think about it.
I own the petty knife since I needed a smaller knife for slicing through chicken and stuff. I saw this and bought it. There was no premeditation so I can't say I made the best choice for the price but I like the knife.
Steel
Ok so this is sandwiched steel and I didn't really know what to expect. It was my first kind of this type of steel. When I first got it I did the tap test where you tap the knife to hear if there is a ding. It usually says the amount of chromium in the knife. Most good knives have at least a small ding because all stainless steel has this. I tapped the petty knife and there was no ding. This made me worry of course. So next I ran the knife on a strop to see how sharp it would get. It got insanely sharp. Arm shaving sharp and could even cut hair if you hit it with a knife. I felt better about the steel after that. I've used the knife for a little less than a month with moderate use (3-4 times a week) and it's still sharp.
Build quality
This knife is light. Like really light. I thought my knife was missing from the box that's how light it was. I would say this knife is more handle heavy than blade heavy, it sure isn't balanced and I would be surprised if it was for such a small knife. The handle is well built and of a decent size. The hammered parts look weird, like they used a machine with too small of a head. You only notice it if you look at the knife for along time though. The clay pattern on it was pretty good in comparison though. I like it.
Final thoughts
It's a unique razor sharp knife that I got for like 40 dollars. I would buy it again for someone else. It has good edge retention and looks nice.
