This new '477' has been specially developed to
replicate as close as possible to the classic Sawyer Bug tying wool. Originally
Sawyer used Chadwicks 477 and as perfectionists found other substitutes simply
did not match the original material for colour. The Semperfli team actually
got a factory to spin some Chadwick's 477 substitute especially! It comes as
a 3 ply making tying of the nice thick Sawyer Killer Bug a doddle. However
to perfectly replicate the original Killer Bug simply split the 477 Substitute
from 3 ply to one and it matches even the diameter of the original 477.
You are buying our Semperfli Chadwick's 477 Substitute not the Original Chadwicks 477 shown
on any photos on this page - they are purely for illustration to show you how close to the
original Chadwick's 477 colour the guys at Semperfli have been able to match the substitute.
The original card of Chadwick's 477 here is worth a small fortune and locked in a safe!
