6Orange Ninja$36pull-through sharpener with 5 sharpening angle slots (12/15/18/21/24 degrees), usable on kitchen, pocket, and hunting knives, made in Chinanot testednot testedtranscript states a result of 45, described as producing the sharpest, most polished edge with no osage-orange residue buildup on the blade unlike Gordon and Kitchellence; FLAGGED as an almost certain dropped-digit caption error, since a durability-test score this low would mean the blade got sharper than brand-new (baseline new-knife sharpness was 140) after 40 abrasive hardwood passes, which contradicts every other knife's result in this same test (all became duller); kept as literally stated rather than silently corrected, most plausible reconstruction given the shared trailing digits would be a value like 445, but this is not asserted as factnot testedsharpness score 410 (transcript renders this as '$410,' a stray dollar-sign caption artifact before a plain sharpness reading, not an actual price), worse than the $2 Gordonimproved to a sharpness score of 240 (transcript renders as '$240,' same stray-dollar-sign artifact), narrowly beating Kitchellence's 265not testednot testednot tested
7Kitchellence$1 for the sharpener as stated in the transcript; this price seems implausibly low for a widely reviewed (~30,000 Amazon reviews) three-stage sharpener and may itself be a garbled/dropped-digit figure, but is kept verbatim per the no-invention rule rather than correctedthree-step pull-through sharpener (diamond rod to repair/straighten a damaged blade, second slot to restore the V-shape, third slot for fine polish), includes a cut-resistant glove, made in China, roughly 30,000 Amazon reviews and described as the most popular knife sharpener on Amazonnot testednot tested265 to 575, a loss of 310 points, described as really struggling in this test; some osage-orange buildup appeared in the blade's bevel but not directly on the cutting edgenot testednot testednot testedsharpness score 265, described as 'by far the best yet' among the sharpeners tested up to that point in the videonot testednot tested

How it was tested

  • initial sharpness after sharpening (Best Certified Sharpness Tester score, lower = sharper)
  • time to sharpen a knife (excluding setup)
  • blade edge durability after 40 passes across Osage orange hardwood with 15 lb of weight
  • percentage of sharpness lost in the durability test
  • ease of setup and use

the wicked edge knife sharpeners are very nice but they're also very expensive for that reason I really like the Work Sharp or the ly [Lansky], both of them are very good knife sharpeners that create a super sharp edge

From the test video verdict.
Data notes and caveats

This video declares a clear category winner for initial sharpness (Wicked Edge Gen 3 Pro, score 90) but its closing overall recommendation is an explicit EITHER/OR between two different, cheaper sharpeners (Work Sharp or Lansky) on value grounds, not a single named 'best overall' product; winner/runnerUp/budgetPick are therefore left null rather than forcing a single pick out of that tie, per the same principle used for other explicit-tie videos in this corpus. All 8 products from the description's Products Tested list are covered. Several brand names required resolution against the description and chapter titles due to heavy caption garbling in this transcript (a noticeably lower-quality auto-caption pass than most videos in this channel): Kitchellence appears as 'kitchenin'/'kelant'/'kence'/'kelin', and Lansky appears as 'lansi'/'lansky'/'lancey'/'lcy'/'ly'. Two numeric anomalies flagged rather than silently fixed: Kitchellence's stated $1 price seems implausible for a ~30,000-review three-stage sharpener and may be a dropped digit; Orange Ninja's Osage-orange durability-test score of 45 is wildly inconsistent with every other knife's result in the same test (all got duller, not sharper, and 45 is even sharper than a brand-new blade's baseline of 140), almost certainly a dropped-digit caption error, kept as literally stated. Wicked Edge Gen 3 Pro's price is never stated in the transcript (the narration moves from the Pro Pack 1's $600 straight into the Gen 3 Pro's specs), so priceMentioned is null for that product rather than assumed equal to the Pro Pack 1.
