The average golf club can last for 10 years.

The average golf club has a lifespan of three years. Thanks to the continuously advancing technology that we have, modern-day golf clubs are now sturdier and come with a better grip.
However, when these tools are not handled properly or misused, they can still be bent and misaligned.
Golf irons are estimated to last between eight and 12 years. This is a decent average, but if you play golf quite often, your irons will probably wear down a bit sooner.
“I should have won the tournament he won,” said Brown. “I was leading and guys like (Lee) Trevino said, ‘You better quit playing so good or you’re going to have to go to Augusta. You know what they’ve got waiting for you there?’ ”
Over their lifespan, golf irons will likely allow you to play over 300 rounds. Various factors can raise or lower this number. For one thing, irons with graphite shafts aren’t going to last as long as those with steel shafts. Graphite shafts tend to get splintered over time that causes the shaft to deteriorate and eventually break. Iron heads are built to be incredibly durable.
Apart from worn grooves, it’s difficult to find a damaged golf head. When your irons have worn grooves, you won’t be able to get the same spin on the ball. As such, your irons will feel slightly dead when striking. If you find six-year-old irons that have only been used to play about 20 rounds of golf, you can consider these differences. The age of the irons, the number of rounds played, and their all-around condition are all things that have to be considered when estimating the remainder of their lifespan.
