I made a plane using the large single iron several weeks ago, for how I use wood stock planes it was too big. This one at 48mm wide is just a couple of mm wider than the Hock double iron I usually use. Functionally not any real difference in size between the LV and the Hock iron. The LV is a little longer than I like but I can get use to it. I wish LV made a little smaller iron for making a "Block" plane sized wood stock.
Use will tell but it seems to hold the set better and is a little easier to fine tune the set.....Could just be first impression or wishful thinking. Did I mention how much easier the build is :-)?
The new LV irons are really flat, about three strokes on the 3mu diamond stone and the back was polished across the cutting edge. Three or four strokes on the "fine" diamond turned a burr on the bevel, a couple more on the 3mu to polish, a fast strop and the iron was ready to go. Not bad for a new out of the box iron. I'm use to irons taking an hour or more (sometimes days) getting prepped for first use, These new LV irons are the flattest I've found, I'm not sure what they changed but what ever they did it's working.
