High quality wedges but I don't know much about wedge grips. I bought this for my SNAW1105 Viking ax when the wood was shrinking leaving the ax head loose. When these wedges arrived I immediately repaired the handle. I removed the head and began driving a wedge into the top of the shaft, and unfortunately the wood snapped when the wedge was not even an inch deep. The wedges are great quality but make sure you know what you are looking for when it matters most as I now have 3 useless wedges and a broken axe.
