These tubular fids make burying lines much easier. Part of the secret to this clever tool is the line snare on back end that holds the line in place while you thread the line in and out.
Extremely well made from stainless steel and are suitable for use with not only 12 strand line, but 3 strand and even double braids as well. No pusher needed.
To choose which Fid is right for you, simply match the size of the Fid to the size of the line that you are splicing.
