As the Flare is worn down from sharpening, the bite angle doesn't change. It's still the same 6 degrees.So your turning advantage doesn't get lost. The total height of the Flare is 6.5mm and most people replace when it's about halfway down the Flare. Because the bite is better at 7/8" on a Flare than 1/2" on traditional steel, sharpening as often isn't necessary. If you are using a 7/8" hollow when the Flare is new, you could switch to a 3/4" as they get lower. I never have. It's all personal preference.The worst case scenario is you leave them too long and they just turn into traditional steel.
