Oh, you mean the double edged blades (as in, they sharpened the lifts and formed the blade so it could just about be installed upside down or right side up and still work) ...
KE4: Hanz's "Sails" appears to mean what you and I may call "Lifts"
When I first started getting those it was pissing me off because of the inventory changes and stock tracking problems I had to fix manually, it was rare for blades to even last long enough to really experience any problems beyond getting bent or massive chunks taken out of the edges from hitting rocks, and it was sorta irritating to me on some blades where there was no way they could be installed upside down - those still only go on one way but the lifts were still sharpened for some stupid reason... Then I realized it was simply the manufacturing process - cut out the flat metal blank, then they sharpen the edges first, (not that they were THAT sharp) before sending the blade through the forming & stamping process followed by heat treat & temper, then powder coat or paint.
I saw no problems reported as far as any changes in lift design, but then in my market, most people are like "long as it cuts, I don't care" and most of the owners concerned with cut quality would buy OEM blades which meant going to the local dealer that sold them anyhow.
