I bought one of these a little over a year ago. I already owned another knife in the Bohler N690 Cobalt steel and love it based on my own experience with it. This one hasn't let me down, either. In a year of sometimes hard use, I haven't had to re-sharpen it once...only quickly run a ceramic across it or strop it every now and then.
As much as I like the knife (and it is my EDC folder), I wouldn't necessarily consider it a "steal" at $90. You can get a good knife for less and probably be happy, especially if you aren't a TOPS fan. You can also pay a lot more $ for a lot less knife and end up with something nowhere near as universally functional as this little pocket puukko. Your $; your call.
