Summary

Dealer listings describe the Daiichi 1530 as a Heavy Wet Fly Hook in 2X-heavy wire V. It is made in even sizes 4 through 16 V.

Photographic record

2 photographs

Bronze fly hook with a straight shank, down-turned eye on the right, rounded bend, and barbed point on the left, photographed flat on blue grid paper.

How to identify it

No maker name or size is stamped on the shank or bend of the photographed hook P. Identification of a loose hook therefore rests on its packaging or the seller’s labeling I. A pack or box showing the model number and size is the firmest identification.

Uniform glossy bronze over shank, bend, point, and eye, with no bare steel or wear-through visible P. Dealer listings give a bronze finish V.

OBS-6SRC-2SRC-3

Dealer listings describe the 1530 with a Sproat bend, a down-eye, a bronze finish, 2X-heavy wire, and a 1X-short shank V. Sproat names a bend family in which the wire leaves the shank in a gradual curve.

On the size 6 specimen the shank is straight and plain, with no ridges, slices, kinks, or bait-holder barbs P. The wire runs in one continuous arc through the bend P. The point is a long, evenly tapered cone with no flat spear facets visible P.

One dealer listing states that Daiichi hooks use a 12-degree constant-taper ground needle point V. That statement covers Daiichi hooks generally, so its application to the 1530 is inferred I.

On the site’s catalog scale, the specimen’s shank proportion falls in the standard group and its wire in the heavy group I. Dealer wording for these two points is 1X-short and 2X-heavy.
