This new ‘477’ yarn has been specially developed to replicate as close as possible to the classic Sawyer Bug tying wool yarn. Originally Sawyer used Chadwicks 477 yarn and as perfectionists found other substitutes simply did not match the original material for color. The Semperfli team actually got a factory to spin some Chadwick’s 477 substitute specifically! It comes as a 3 ply making tying of the nice thick Sawyer Killer Bug with ease. 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 in the comparison photo at the top of the page. The Sawyer Killer Bug has been a very popular subject in the Tenkara world and now you can tie your own with a yarn that is as close to the original as it gets.
