The Midge size is perfect bobbin for tying small flies, standard is the universal bobbin good for just about anything and the bass is a long tube bobbin that really helps tie the larger flies. These superior ceramic bobbins are well made. They have ceramic inserts in top and bottom of thread tube. This makes thread grooving of this tube next to impossible.
This is one of those tools that every tying bench should have. Owning one of these devices eliminates the frustration of tying to re-thread your bobbins after an accidental breaking of thread while tying.
Every fly tying bench will have one or more of these tools. They may look different but they all work the same - yes even the wine cork and needle version. However this one looks better and has a half hitch knot tying opening in the other end of the brass handle.
Proper use of this tool will increase tying productivity and more importantly durability of finished fly. Some materials are just very hard to hold onto and wrap snuggly around the hook shank. This easy to use pinching plier type tool holds the material securely while you wrap them on or around the hook.
To dub normally is much easier but dubbing with this tool makes for better results. The bodies of this dubbing method are plusher and will hold together longer. The actual dubbing is trapped between two strands of thread and then twisted together to make a dubbing rope. You can use wire instead of thread and now it is a dubbing brush strand. Make sure to get this demonstrated to you at your next visit to fly your favourite shop - you will definitely like the results.
