I thought that this would be very simple, but it was a long time ago since I have removed a knock from a 2216 (2117) arrow. IF I remember correctly, we just used the flame from a candle to heat the knock then pull it out. I have 2216 factory arrows (excalibur) with the black knock. Is there a newer trick to do this, or do I just need to add more heat (longer time over flame).

I just received my tracer knocks and I want to exchange the knocks on a few arrows to be able to test them.

Thanks.
