Well I will agree on the little cement bottles i LOVE em!!! and yes I have had problems with the glue drying up but whatever the bottle are only like 3 buck each!!!
Whip finisher dont use it just use fingers instead, might not be doing it right but oh well it works and besides i cement all my heads.
bobbin threader dont use em the ole feed an suck LOL works for me!!! roflol!!!!
And finally Hackle pliers i dont use either i find the hackle just breaks when i use em better lucks with fingers. Although having said that they can be useful when the thread breaks mid tie.
