The chart is not complete. Some hooks are still on back order. Two tests remain to be completed. Quick summary - Test results so far show that pre-tied assist hooks using a Mustad jigging hook are the weakest hooks in this entire list.

Bend tests are reported by how much the gap opened at increasing weights. Numbers shown are in millimeters. Hooks that stretched badly are marked where they failed with a RED "S".

Hooks that survived the initial bend tests at 100# went on to the next round of Tip Test torture. There are a bunch of bent hook pictures in Post #14.

The hooks 7/0 that still looked like hooks at the end of the day included AGOOL, ANIBBY, Bearkin, JShanmei, Mustad 7691 (barely, see pix in post #14), Owner Gorilla, and SENYUBBY (the hook that looks like it could tip a gaff in the lower right corner).

Check this out. All 7/0 hooks are far from equal when it comes to overall size, weight, style, or price.

The difference in size from the largest, JShanmei, Mustad Sea Demon, and Senyubby, to the smallest, Derkerl, Mustad pre-tied, and Blue Wing, is remarkable. The middle hooks, top and bottom, are both Mustad 7/0.

Every package reads 7/0 but some of them are a LOT bigger than the others. Trying to order the same actual size for next time.

Downsize the really big hooks to 5/0 - AGOOL, ANIBBY, JShanmei, Mustad 7691, Mustad 7731, Mustad 9174, SENYUBBY
Upsize the small hooks to 9/0 - Bluewing, Centaur Classic, Centaur Penetrate, Derkerl, Eagle Claw 118Mag, Mustad 10881, Mustad Pre-tied, Owner Gorilla

BEND TEST
The hooks were loaded with weight, 35#, 45#, 55#, 80#, and 100#, and the number in the chart reflects the increase in the gap. Results were reported in millimeters.

When the hook point was 90˚ to the line of pull, it was considered to have failed, and marked with an "S" for "stretched" in the chart.

DERKERL 7/0 (Amazon) testing 55#

The starting point was a 35# load, the approximate drag used on a 100# rod and reel. The 45# load simulates the max drag on a 120# rod and reel. Loaded with 55# of weight is beyond the capacity of most gear and most fishermen, but might occur during the course of a fight. The bend tests at 80# and 100# put the hurt on most of these.

Hook loads were compared using both a single point of contact and with the weight spread out in the bend. Single point of contact is shown below.
BlueWing55.jpg

The picture above is a BlueWing 7/0 hook, one of the smallest of the 7/0 hooks tested, under a 55# load. Its gap opened 3 millimeters.

The picture below shows the weight spread out on the bend. The two methods, single point and spread-on-the-bend gave similar results. There was little if any difference.
BKK55.jpg

This is the BKK Jigging hook. It was one of the hooks that opened up the most at 4mm. Most of us are never going to put 55# to a hook, but here's what it looked like. I don't see it anywhere near pulling out.

ALL the hooks passed the test at 55#. The best of the hooks only opened up ONE millimeter under 55# of load. The lightest of the hooks opened up FOUR millimeters under 55#. When the load was released, for the most part, they returned to their original shape.

Two things that haven't been accounted for include the hooks' sharpness out of the box and the eye construction. While two of the Mustads are welded similar to the trebles, the rest are only bent closed. Some of them are tight with no sharp edges to cut a snelled assist-tied hook, but others are a bit crude and the end of the wire seems sharp.

I got of few of the 7691’s with the closed welded eye, I can send you a couple 7/0s in the name of science if you want

will you upload any video of the test?
What's your opinion on tipping rude crew members? How do you tie a Surgeon's knot? How do you feel about last minute fuel surcharges?

Videos are for YouTube. I'm not getting paid enough.

    Don't tip the rude crew members. And as for youtube, you can share YouTube link here, would like to support your channel if you have any.

    Interesting that the Mustad Pre-tied Assist hook was the FIRST TO FAIL out of the seventeen hooks tested.

    The chart in the first post has been updated a bunch. Looking at pix of hooks holding up 35-55 pounds and not doing much is really boring. It's more fun looking at the trashed hooks with some real weight on them.

    Some pix of Bend Tests @ 100# below

    Centaur Classic Jigging (Tackle Direct) @ 100# and getting ugly

    Mustad 10881 Jigging failing @100#
    IMG_4836.jpg


    Mustad Pre-tied Assist Hook failing at 80#
    IMG_4838.jpg


    Hooks that were still looking good after success @ 100# on the bend went to the Tip Test for ultimate torture. A tip test, shown below, @ 45# is much more than the bend test @ 100#.

    AGOOL (Amazon) @ 55# Survivor
    IMG_4817.jpg


    Bearkin 8/0 killing it at 55# on the tip. This is one of the smaller, less expensive, stainless hooks that always finishes near the top. The right size for green mackerel too. The eye is a bit crude, but we'll get to eyes later.

    BKK 10881 dying a slow death @ 55# in the Tip test.

    Centaur Classic Jigging (Tackle Direct) retiring @ 45# on the Tip Test. It was already ugly at 100# on the Bend.
    IMG_4824.jpg


    Centaur Penetrate Jigging (Tackle Direct) failing at 45# on the Tip Test
    IMG_4829.jpg


    Eagle Claw 118 Mag @45#. You decide. I wore safety glasses. The hammer is about to slip.

    Mustad 7691 Southern Tuna Ugh @ 55# Tip Test. The gap has widened 17 millimeters.

    Considering the size disparity in different brands and styles, some hooks could have been 5/0 or 7/0 or 9/0, and they would have been the same actual size.
    Outstanding scientific work! We need more work/study like this in fishing. The thing that really gets me is that there is no standard hook sizing. So when fishermen talk about their hook size, it means nothing. I am glad you were able to shed light on these issues.
