Doc Griffin: Blades vs. Cavity Backs

Wed, 10/31/2012 - 19:05 -- Don Trahan

Have you ever wondered what the difference is between a blade iron and a cavity back iron and which one would better suit your game? Craig Morgan had this very question so I enlisted the help of our Director of Club Fitting Operations, Doc Griffin to explain it in detail.

I love your intructional videos and have a question regarding what type of irons I should buy...cavity or blades. I have been looking around and love the look and feel of the blades, but keep getting put off by the salesman stating you need to be a low handicapper to hit them. My handicap is 15, I would love to hear your thoughts on this please.
First of all, Doc states that taking the advice of most salesman is kind of like a pencil with no lead...it's a little bit pointless. Most of them are just reciting whatever it is they've been told to say. As far as what club design works best for you, there's different variables that will determine what fits you best.
 
A blade refers to the profile of the club which would be the top line and the sole. But, not all blades are muscle back. We have to be careful that we're talking about the same thing and meaning the same thing. Mr. Morgan is probably referring to the muscle back design not the cavity design. Nevertheless, elements such as where the weight is, the length of hozel, offset, length from heel to toe, and length from sole to top line are the real measurements that matter.
 
The slower we get with our clubhead speed, the more help we need getting the ball airborn with the right trajectory. For players who need that help, a low deep center of gravity offset from the face would be more beneficial to help them play better golf. But, in order to find that kind of club you're going to be looking primarily at the larger head cavaity back clubs. It's all a matter of preference but the clubhead design that matches the need of the player is the most critical aspect. 
 
Of course, this is all irrelevant if you don't have the right shaft to go with the club. If you really want to get what's best for you and understand the ins and outs, then get to a certified professional club fitter that will help you understand the process more clearly.

Doc, right on the money with your response to Mr. Morgan. You simply can’t walk in to a golf super store and purchase a set of irons from a salesman who might or might not know what he is talking about. Granted there may be some competent salesman in some golf stores (hard to find) but if you are not fitted properly for a set of golf clubs then you are wasting your money. You cannot have someone sell you a set of clubs without going thru a proper fitting process. Additionally this process must be handled by a professional and qualified fitter. Most in store salesmen know how to handle a launch monitor or simulators that will give you spin rates and launch angles. But in true a term that’s all they can give you and then they really don’t know what to do with this minimal information. This is not a completed procedure to be properly fitted for a set of clubs. In you next blog you might want to remind-review with everyone what is involved in a proper fitting process.

Thanks again , I enjoy your Doctor’s House Calls.

Good to hear from you Lynn. Hope you and yours are well. I know you've been out west in Arizona to do an outing/fitting (or was that yet to happen, I lose track). Any how I may have attended had my shoulder(s) been in golfing form.
Nice piece on club heads. It seems the lines have blurred a bit on which are blades, cavity back, muscle back, composites or a combination of various aspects of all. You may know my scoring clubs are Japaneese forged Vegas. I consider them to be in the sort of blade with a mild cavity back class. Sure love em any way. Then my 4-6 are the Redline Adams hybrid irons A composite cavity back with low COG and provide great length on long iron shots. Really comes down to feel and results. i am with you 100% on the need for a professional fitting. Preferably with a certified PPGS fitter in your class:)
