The Rebate router set for guitar bindings is really good. I've previously cut the bindings channel by hand, but this tool makes the task so much easier. I used it on a tenor guitar (so quite tight bends), with walnut sides and a cedar soundboard, using a Triton JOFOO1 router. The router might be considered quite heavy, but I opted for stability over manoeuvreability. This router bit cuts like the proverbial hot knife through Butter! The cut was extremely clean on the walnut, with only a little furryness in a couple of places on the cedar - easily cleaned with a bit of sandpaper (that might be avoided using a higher speed, I had the router set at its slowest speed). This router bit is well worth the price, if you're thinking of getting one I'd highly recommend it. The time from ordering to delivery is very quick too.
