Technical profile and measurements
| Feature | Recorded | Evidence |
|---|---|---|
| Eye | Looped Eye, Turned UpShow noteHide noteClosed wire loop; the free end tapers to a point alongside the shank, probably the seam near the eye PI. Dealers list a tapered-loop up-eye V. | OBS-1OBS-4SRC-1SRC-4 |
| Wire | Fine (1X Fine), Round | |
| Shank | 2X Long — Curved / humped | SRC-1SRC-4OBS-5 |
| Bend | Sproat, Narrow gapShow noteHide noteSmooth round bend with a short, nearly flat lower run; point nearly parallel to the shank P. Bend position is closest to the site's Viking group I. | |
| Point | Standard / SpearShow noteHide noteSmall, short barb cut on the inner side of the point, angled back toward the bend and set back from the tip P. | OBS-8 |
| Finish | Blued — stated on packagingShow noteHide noteDealer listings name a blue finish V. The specimen's coating is glossy, deep navy-blue to blue-black and smoothly applied P. The coating process is not documented. | SRC-1SRC-4OBS-9 |
Dealer listings offer sizes 2 to 8 and describe a slightly curved shank and a slightly offset point V. They do not state the direction of the offset or give dimensions.
The size 6 specimen measures about 30.6 mm (1.21 in) in length, with a 25.0 mm shank, a 7.7 mm gap and 0.8 mm wire, all by caliper P. The recorded gap value does not state where it was measured from. Its shank proportion falls nearest the 2X long group and its wire thickness nearest the fine (1X fine) group in the site catalog I.
In the flat photograph the shank reads straight P. A curve or offset out of that plane cannot be judged from the images.
