There are tool marks and there is damage. I would have to see them to know if they are actually damaged or compromised, of it it’s just the tool mark from bending. Sometimes it’s not easy to tell the difference. Generally, if it looks like a crease, it’s damaged and the hosel is compromised. If it looks like a slight dent or impression, it could be just a surface mark on the chrome and not a problem. If it is compromised, we would have to strip the chrome, break and re-weld the hosel, then rechrome. After this process the loft and lie can not be adjusted due to the weld. If it’s just tool marks, the chrome may still have to be stripped and then, depending on how deep the dents are in the raw carbon steel, we could attempt to remove some of the dents. Then, the head would have to be rechromed to prevent rusting of the carbon steel. If the dents are very shallow and barely noticeable, it might be possible to buff them out some. Only way to know is see the heads. If the stripping of the chrome and re-chroming is required, you’re looking at probably 6 – 8 weeks and $60.00 per club. Removing the dents, etc. can be more, depending on how much is required. For budgeting purposes allow for an additional $16.00 for cleaning up the dents and if welding is required, another $16.00 per head. So, it cold be approaching a $100.00 per head if all has to be done. The main thing is to determine if the heads ae damaged or if it is just tool marks.
