to 120, lost 30 points, still the sharpest of all 8 knives after this test, though 3 other sharpeners (Lansky, Work Sharp, Wicked Edge Pro Pack 1) ended up tied at 125

to 125, still extremely sharp

to 130, lost 25 points, held up really well

to 125, lost only 15 points, still very sharp, and had the LOWEST percentage sharpness loss of all 8 sharpeners at 13.6%

to 125, still very sharp

transcript 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 fact

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 edge

to 470, a loss of 120 points; some osage-orange residue built up on parts of the blade but not directly on the cutting edge

same as the Pro Pack 1

its sharpening stones are about 50% wider and 50% longer than Work Sharp's and Lansky's, which speeds up the process, and changing stones is quick

not including setup time; slower than the pull-through sharpeners but this is expected for a guided-rod system

about 2 minutes longer than Lansky, attributed to having more sharpening stones starting at a less aggressive grit

score of 90, the best (sharpest) initial result of all 8 sharpeners tested: 'when it comes to initial sharpness the wicked edge gen 3 Pro came out on top with a sharpness score of 90'

score of 100, tied with Work Sharp for 2nd-best initial sharpness of all 8 sharpeners

score of 105, very close to Work Sharp

score of 110

score of 100, tied with Wicked Edge Pro Pack 1 for 2nd-best initial sharpness, sharper than Lansky
