My favorite boning knife is the Dexter V-lo® 6 inch boning knife. No matter how slick and icky your hand gets, the grip feels solid. I did sharpen the back side of the tip for about 1/2 inch , though and round the tip just a tiny smidge. That makes it much easier to work your way around to de-bone a small bird or follow the bones down to clear the tendon and pull it out along with the bone for de-boning legs to stuff them. I do a lot of stuffed chicken legs. . . my kids have always loved them.
Here’s a picture . . . isn’t it pretty? It holds an edge very well, sharpens easily too.
And it was under $25.
