The Konosuke HD's are going to be very nice. A hard to beat knife really.
The Richmond Artifex is a great budget level knife but not in line with the HD's from Konosuke.
Other than that, the Richmond Addict is nice.
The Richmond Laser is a great knife series.
Suisin Inox Honyaki's are hard to beat, but they've gotten spendy.
The Kikuichi TKC is a killer knife for the price...but Western handled.
With a budget like that, you've really got a lot of options. Maybe, can we narrow it down with some other requirements? Damascus or no. Kind of mighty or super thin? Anything else come to mind?
