    tied for second place with the Irwin and Wilde Tool, behind the Tsunoda

    first place overall

  • 2Crescent
    196 in lbs2nd

    second place behind the Tsunoda, and held up nearly as well for wear

  • 3Harden
    134 in lbs

    teeth described as more pointed than the Olympia Tools, which the narrator says explains the higher score

  • 4Olympia Tools
    113 in lbs

    did not perform as well as the Harden; the narrator attributes this to less pointed teeth than the Harden

    158 in lbs

    tied with the Wilde Tool; teeth held up about the same as the Olympia Tools

  • 6Kobalt
    135 in lbs2nd

  • 8Urrea
    99 in lbs

    last place; teeth not as pointed as other brands, though they held up fairly well despite the low score

    teeth described as offering less bite than some other brands but holding up fairly well

  • 10Stanley Proto

    no explicit numeric figure for this brand appears in the large-bolt-grip section of the transcript, unlike every other brand; a genuine gap rather than a stated skip

  • 11Wilde Tool
    158 in lbs

    tied with the Irwin; teeth held up really well

  • 12Martin
    175 in lbs

    better than average; teeth held up really well

    fifth place (behind Tekton 168, Martin 178, Crescent 203, Kobalt 206)

  • 2Crescent
    203 lbs3rd

    third place behind Tekton and Martin, though the cutters experienced more damage than some other brands

  • 3Harden
    228 lbs

    survived the cut but with quite a bit of damage to the pliers

  • 4Olympia Tools

    not mentioned in this section of the transcript; a likely skip given it already failed the smaller six-penny nail cut test, though no explicit reason is stated

  • 5Irwin Vice Grip
    232 lbs

    cutters held up quite a bit better than the Harden's

  • 6Kobalt
    206 lbs4th

    though the cutters experienced more damage than the Irwin's

  • 7Channellock
    226 lbs2nd

    briefly second place behind the Kobalt at that point; cutters held up really well

  • 8Urrea

    was not able to cut through the 16-penny nail, only bent it; handle developed quite a bit of wobble after the attempt, though the cutters remained in good shape

  • 9Tekton
    168 lbs1st

    first place overall, moving into the lead over the Crescent

  • 10Stanley Proto
    225 lbs

    not enough to take the lead; cutters remained in great shape

  • 11Wilde Tool

    the rivets stretched during the attempted cut and the pliers were not able to cut through the 16-penny nail; a small amount of damage to the cutters

  • 12Martin
    178 lbs2nd

    second place behind the Tekton; cutters remained in great shape

  • 13Vampliers
    not tested

Wear Resistance Assessment

    teeth experienced quite a bit of wear from the impact-wrench exposure

  • 4Olympia Tools

    no separate wear commentary beyond the grip-strength comparison to the Harden

    named in the closing subjective summary as one of the best brands for wear resistance, alongside the Wilde Tool and Vampliers

  • 11Wilde Tool

    named in the closing subjective summary as one of the best brands for wear resistance, alongside the Stanley Proto and Vampliers

  • 13Vampliers

    teeth held up the best of all brands at that point, with very little wear; named in the closing subjective summary alongside the Stanley Proto and Wilde Tool as among the best for wear resistance

How it was tested

  • grip strength on a small bolt clamped in a fixed handle-spacing jig applying about 100 lbs of squeezing force, measured with an electronic torque adapter, in in lbs
  • grip strength on a metal roofing screw gripped from the front of the pliers, in in lbs
  • force required to cut through a 6-penny nail using a hydraulic press applied to the pliers' handles, in lbs
  • grip strength on a larger, harder bolt using the same jig methodology, in in lbs
  • wear resistance of the teeth after 5 seconds of impact-wrench exposure, assessed subjectively
  • force required to cut through a 16-penny nail, in lbs
  • overall subjective damage assessment of each brand's condition after all tests

for fourteen dollars i really like the snow to brand

From the test video verdict.
Data notes and caveats

13 brands tested (Vampliers, Kobalt, Irwin, Stanley Proto, Channellock, Tekton, Martin, Wilde Tool, Urrea, Crescent, Harden, Olympia Tools, Tsunoda per the description). Several brands are consistently phonetically mangled throughout this transcript (Tsunoda as sonota/sonoda/snow to/cenote, Urrea as urea/yuri/erie, Tekton as tecton/tekken/technique, Vampliers as van pliers/vamp pliers/vampire's/vampires, Wilde Tool as wild tool/wild two); all resolved against the description's product list with no ambiguity since each phonetic variant is used consistently for one brand throughout. The video's closing verdict is a casual list of personal favorites (Tsunoda, Channellock, Crescent, and a caveated Vampliers) rather than a scored average-finish ranking like some other videos in this channel; Tsunoda is treated as the winner since it is named first, most enthusiastically, and won or tied for first in three of the five graded tests. Stanley Proto is missing a numeric large-bolt-grip figure despite being tested in every other category, a genuine transcript gap. The verdict quote's stated price ("fourteen dollars") does not match Tsunoda's own introduction price of $12 earlier in the transcript, though it does match the price given for Crescent, Urrea, and Tekton; kept both prices, flagged as an unresolved discrepancy rather than corrected.
