1. A blade for a bladed rotor, the blade having an attachment, the attachment having concave and convex flanks and proximal and distal ends, the proximal end having a chamfer feature in the form of a single chamfer proximate the convex flank.2. The blade of claim 1 wherein the attachment has a lateral width and the chamfer feature extends substantially the entire lateral width.3. The blade of claim 1, wherein the chamfer feature has a maximum depth proximate the convex flank.4. The blade of claim 1 wherein the attachment has a lateral width and the chamf...
