sanelli and dick knives (always makes me chuckle) are good. Just try walking into a shop and asking for a 6 inch Dick boning knife and keeping a straight face!!
I have 3 sanelli's and all can be made razor sharp in seconds and keep a good edge, although i have snapped a small paring knife blade being a bit rough, so maybe not for really heavy carcass work (for that i use my fallkniven PHK which is perfect)
