Abstract

A fly tying tool can include a base and a shaft that rotates relative to the base. The shaft can form a fly securing portion that includes a magnet by which a fly can be secured to the shaft. The fly securing portion can also include a hook feature spaced from the magnet to form a recess in which the fly may be placed. The shaft can include a threading structure in the form of a spiral to facilitate threading a line through the eye of a hook.

Claims (31)

1 . A fly tying tool comprising:

a base; and

a shaft coupled to the base, wherein the shaft is configured to rotate relative to the base;

wherein the shaft includes a fly securing portion having a magnet for securing a fly;

wherein the shaft further includes a threading structure positioned on the shaft adjacent to the fly securing portion, the threading structure comprising a spiral defining a central channel, wherein the spiral is configured to guide a line through an eye of the fly while the fly is secured by the magnet.

2 . The fly tying tool of claim 1 , wherein the shaft is rotatably coupled to the base about a longitudinal axis.

3 . The fly tying tool of claim 1 , wherein the fly securing portion includes a hook feature that extends outward from and is spaced from the magnet to form a recess configured to receive a portion of the fly.

4 . The fly tying tool of claim 3 , wherein the magnet is positioned at a face of the fly securing portion facing the threading structure.

5 . The fly tying tool of claim 4 , wherein the magnet is positioned within an opening in the face such that the fly is seated within the opening during use.

6 . The fly tying tool of claim 1 , wherein the spiral has a bottom end and a top end, the central channel extending from the bottom end to the top end, the central channel being sized and shaped to receive and direct the line toward the eye of the fly.

7 . The fly tying tool of claim 6 , wherein the top end of the spiral forms an eye receiving area for aligning the eye of the fly over the central channel such that the line is guided through the eye by movement along the spiral.

8 . The fly tying tool of claim 7 , wherein the eye receiving area is positioned adjacent to the magnet so that the eye of the fly is aligned with the central channel while the fly is magnetically secured.

9 . The fly tying tool of claim 1 , wherein the threading structure is formed on an extension from the shaft projecting from the fly securing portion.

10 . The fly tying tool of claim 1 , wherein the threading structure is integrated into the shaft along a longitudinal portion thereof.

11 . A fly tying tool comprising:

a base; and

a shaft coupled to the base, the shaft being rotatable relative to the base;

wherein the shaft includes a threading structure comprising a spiral having a bottom end and a top end and a central channel that extends from the bottom end to the top end;

wherein the central channel is configured to guide a line through an eye of a fly positioned at the top end of the spiral;

wherein the spiral is configured such that, as the shaft is rotated, the line is routed through the central channel until the line is freed from the top end of the spiral thereby threading the line through the eye of the fly.

12 . The fly tying tool of claim 11 , wherein the top end of the spiral forms an eye receiving area configured to position the eye of the fly in alignment with the central channel.

13 . The fly tying tool of claim 12 , wherein the shaft includes a fly securing portion having a magnet for securing a fly positioned adjacent to the eye receiving area.

14 . A fly tying tool comprising:

a base having a first end and a second end and a channel that extends from the first end to the second end; and

a shaft comprising a first end forming a fly securing portion and a second end forming a coupling portion that inserts into the channel in the base to secure the shaft to the base, wherein the shaft is rotatable within the channel in the base, wherein the fly securing portion includes a magnet for securing a fly to the shaft, wherein the shaft further includes a threading structure comprising a spiral positioned adjacent to the fly securing portion and defining a central channel configured to guide a line through an eye of the fly.

15 . The fly tying tool of claim 14 , wherein the fly securing portion includes a hook feature that extends beyond the magnet and cooperates with the magnet to position the fly.

16 . The fly tying tool of claim 14 , wherein the spiral has a top end that forms a fly receiving area, the fly receiving area being positioned adjacent to the magnet and aligned with the magnet to position the eye of the fly over the spiral.

17 . The fly tying tool of claim 16 , wherein the spiral has a bottom end that is formed on an extension from the shaft and is configured to receive a line prior to guiding the line toward the fly receiving area.

18 . The fly tying tool of claim 6 , wherein the spiral is configured such that the line enters the bottom end and exits the top end through the eye of the fly without manual threading of the eye.

19 . The fly tying tool of claim 11 , wherein the spiral is configured such that the line enters the bottom end and exits the top end through the eye of the fly without manual threading of the eye.

20 . The fly tying tool of claim 17 , wherein the spiral is configured such that the line enters the bottom end and exits the top end through the eye of the fly without manual threading of the eye.
