Thanks guys, believe it or not I have been using a reef knot on some of my larger sized hooks 2's and 1's.
For the smaller sizes 8's I simply use tying thread because there are less fingers and thumbs in the way and with my tying style obtain a neater finish.
The confusion came about because an angler I met in the Bahamas told me it was not a reef knot but a totally different knot.
In the UK many of us call the uni-knot a grinner knot and have seen our blood knots called by another name in other countrys.
Maybe someone out there should make translation books on knots and tackle.
Thanks again.
