The Griffin Fly Tying Bobbin comes in two styles of bobbins, standard and ceramic tip. The standard bobbin is very similar to a Matarelli bobbin, but has black plastic spindles instead of brass spindles on the legs that fit into the hole through a spool of thread. This is a very good bobbin that will last many years. The ceramic tip bobbin is the same as the standard, but has a flared tip that contains a ceramic insert.
