I found this thread quite annoying as nobody has said what magazine you are talking about, what the plans look like & it was only until I could see a picture (the 1st one had a broken link) that I knew what you were all talking about. Perhaps it would be better to give a bit more detail in the opening post for things like this, as a lot of readers will probably be in the same position as me, wondering what was being talked about..
I can see what you mean about the skill level required, as some of those notches are amazing & i would find then quite hard to do on a workbench. This seems be be several levels up from carving a spoon, which is a daunting enough task for newbies. Time I got myself a spoon knife & got started on this wood carving stuff.
