Thanks, I believe you are correct that the "width" is being measured at the very wide lift area. I'll check out those blades. I also ran across a site with tons of blades on Amazon - the Rotary store. A lot to chose from for all brands. The one thing missing from most all sellers is a edge profile image of the blade. (Edge on/narrow side view. I sharpen my own blades and these high lift blades have some extensive curves in them that make sharpening a lot of work even with a grinder. The image attached shows a lot of the curves in the blade but it would still be helpful to see a full side -edge on view of the blade. Notice that this one has a center section pressed upward and that means the cutting edge of the blade is actually going to be below that of a perfectly flat blade even if the flat blade had the curved trailing edge.
