A rodbuilder can fix it functionally "good as new" if he's willing to do the work. I'd ask how much it would cost to see if it's worth the expense. Per Tom Kirkman, a premier builder in High Point, NC, a good repair will use 3 pieces of blank, a graphite piece epoxied to the inside to maintain the backbone and sensitivity of the blank, a second graphite piece over that, cut to length so you maintain the length and original taper of the original rod, and a 3rd piece, fiberglass not graphite, which is epoxied over the repair area to insure the integrity of the repair. Most rodbuilders have a box of rod blank pieces saved to do repairs and to extend rod lengths. I have a 7' Rogue rod I did this to and have used it continuously for 5 yrs with no problems whatsoever. If a repair is not feasible, I'd certainly harvest all the guides off the blank to use as replacements in case you need them.
