Most of my hand tools are Veritas, which I really like. Some pre-date the introduction of PM-V11 and I replaced most of the irons with that steel as I like it more than A2 or O1. I have several LN planes (#4, #3, and #2) with A2 irons. I would like to replace the irons with Veritas. I see that Lee Valley as PM-V11 irons for Stanley planes, but I am not sure if they also fit LN planes without modification. Would appreciate insight from someone who has done this before.
