Lee Valley has offered tapered plane irons for awhile. I finely got around to ordering a couple and yesterday I made a Krenov pattern plane with a Beech stock using one.
They're pretty slick. If you are like me and hate powered routers the cutting of the mortise for the double iron screw is the most time consuming step in making a Krenov plane. A single iron doesn't need one so there is one less step to screw up.
Anyway, the first is out of the clamps. I tried it on some Cherry scrap, works beautifully, easy to set and holds the set. About the only down side is the iron is a little longer than the Hock Krenov irons. I can live with that.
It's not the best stock I've made, the mouth is a little loose but it works so I'll add it to my user shelf.
