With this in mind, let’s get started with some general tips on spotting the differences between a counterfeit and authentic club. How to Identify Counterfeit Golf Clubs The first thing you will notice about a fake club is the quality doesn’t compare to the real deal. If held side by side with an authentic club, it will be easy to identify the counterfeit golf club because of the inferior quality. Since you normally don’t have a known authentic club to compare to, let’s get started with some detailed analysis of the differences starting with the grip. Counterfeit Grip Details • May have a strong rubber odor like a swimming pool float or a bicycle tire. • The grips logos may also not be aligned properly when the club is sitting at address. • If there is a brand logo, many times the paint fill will be coming out and the font will be slightly different.

• The design of the grip may not match. Sometimes the grip design will be from an older model club. See our post for an example or look at the image below. • Many of the counterfeit grips we have seen on counterfeit clubs have also been smaller around like a ladies size grip. This counterfeit grip was a design used on TaylorMade Irons from several years earlier. Counterfeit Ping Grip on the left. The paint fill is not solid and the grip is smaller than the authentic one on the right.

The counterfeit Scotty Cameron grip on the bottom is totally different than the authentic. This was a design used on older models. Counterfeit Shaft Details • Counterfeit shaft bands tend to peel up and are not straight on every club. Also, they could be in a different place between clubs for an iron set. • Many of the shafts will feel flimsy or not as stiff as the flex stated on the shaft. • The colors may be off on the shaft bands or the graphics if the club has a graphite shaft. Check out our counterfeit Iron Set Post as an example of counterfeit Project X steel shafts.

See our post on a we received to see an example of a graphite shaft. • Many of the major manufacturers have started putting a holographic sticker on the shaft. As a result counterfeiters have followed suit, but they are not putting it in the same location. Most stickers on authentic clubs are placed on the underside of the shaft up by the grip or down next to the ferrule. Counterfeit clubs usually have this sticker near the shaft band on the top of the shaft so it is easily visible.

They figure it will make it look more authentic I suppose. You can check our post for a good example.
