I've used shims with good success, however, they do shorten the life of the handle,hence, it's only a temporary fix... If you throw as much as I do,it's not too long before it starts to crack where you jammed the wedge in, and I'd used a saw prior to installing that wedge. Two Hawks has the best method, I've never replaced a handle on mine, I have four of his hawks. In fact, none have ever come loose. I've replaced so many handles on the 'hawks made in India and my Canadian Blackhawk that I couldn't tell you how many. It's a real chore getting that one degree taper in the eye, but well worth it in the long run. When the fit is right, and the head is pressed on, it won't come loose.Good Luck!
