Yeah, I know what you mean.Cedric & Ada Gear and Outdoors --I used to like this channel, but eventually I just realized the whole methodology and comparison was wrong on many levels--one of the biggest mistakes is how he ranked all the knife steels' edge retention performance based solely on how many times an edge can cut thru ropes, while ignoring geometry and other factors.
For example, one could say Spyderco FFG Delica in VG10 is able to make 5 more cuts than a Mora Survival in Carbon steel, but it is just wrong to conclude that all VG10 can make 5 more cuts than all Carbon steel, since Spyderco and Mora are so different in geometry.
Don't get me wrong, I do have nothing but huge respect for Pete, all the great work for complying the data and doing the tests over the years, but the way the data is being interpreted contradicts with I've learnt from Larrin's article about geometry affecting the edge retention.
Pete himself says he's not fully scientific and I've seen him test same steel several times but on different knives. While he does try to sharpen some knives to same angle - you can't change entire geometry. So, yes, exactly as you said. Full flat grind Spyderco will cut longer than some other knife in saber or scandi grind despite using the same steel.
As opposed to pure edge retention videos, his reviews about knives do serve the purpose if you want to buy that particular knife. Because you don't just see edge retention of that same knife, but you also see him use it for some general purpose tasks.
