If I’m right in thinking please correct me if I’m wrong, but isn’t the 60 1/2 designed to be used mostly on end grain because of the low angle of the blade I’ve got both and over the years I’ve had Stanley and the Irwin equivalents which are cheaper and in my opinion just as good!! But I prefer the 9 1/2 as it seems to work better on the face or sides of the timber.........😀
