The biggest advancement in clubs is the enlarged faces for more forgiveness and not the horrible results on old blade irons when you miss. Cavity backed balanced clubs made a huge advancement for amateurs.

I would only hit a pure shot off my old Hogan blades about 3-4% of the time. It still is the most incredible feel. No cavity back club comes close to a pure blade strike. Problem was they were so ****ing hard to hit, miss hits were ugly as shit, and the worst was trying to muscle a 5 or 6 iron out of deep rough. I could NEVER get good contact. Lastly, hitting a 2 or 3 old tiny blade iron was the most difficult thing to do. Maybe a good strike was only 1 per thousand for me. Hated it and used a 5 wood whenever possible. Hybrids and cavity backed clubs to replace the 1-4 irons were a huge help for all amatuer golfers.
