Yeah I'm unsure of what to think of this comparison. I have mainly used the edge pro the last few years and gotten pretty proficient with it. I prefer it over a wicked edge because of the extra freedom in blade positioning. The learning curve goes a bit higher then the wicked edge which I find the most fool proof method but with enough experience I find I can manipulate the edge pro to a great variety making all sorts of tasks like sharpening to the base of the ricasso on spyderco blades a breeze where I would find it more difficult with clamped systems for example.
I'm not sure what to make of these results neither. Perhaps it's his level of experience with the edge pro but when I finish my blades on the high grit diamond matrix stones or shapton stones (depending on what material I'm working with)and a quick strop I end up with a wicked sharp and durable edge far surpassing 'original sharpness' (what is this benchmark anyway? If you aren't getting these results you're doing something wrong I would think?).
Now I wish I could speak for freehand, but due to an injury from being hit by a car I've lost the finesse in my right hand to get results after going up to the finer grits which.. Is okay due to the edge pro being a middle ground in clamped and freehand but still a shame nonetheless. I love seeing Michael Christys work and the man is a legend. I wish I could put in the years to get on his level but it'd be pointless.
Also, I love the custom options the edge pro comes with. First of all a variety of stones to work with, things like the small knife attachment and for bigger blades the knife slide guide combined with a magnet effectively holds the knife in in a place of your preference or required place to work on exactly that part of the blade you need to.
So I'm not sure about any of this. I guess as a basic comparison between how barebone systems compare in their workings it's okay but I feel this is not nearly telling the entire story between how to get the most out of a certain system and therefor the results are pretty out there imo. I'd suggest looking up experienced users of each method of sharpening and hear their views on the matter.
I think (though never experienced) the apostlep used the edge pro with great results but for a better explanation and use of this system I'd recommend the channel of spadeknifeworks. Hugely under appreciated channel because this guy knows what he's doing for sure.
Here a video on his reasoning behind the edge pro and I concur with his findings: https://youtu.be/fHyhHwQ1TnI
Skip to 4.30 for the real vid, the start is a comparison between the apex and the pro model. If you're interested in the edge pro or debating on whether a kme or wicked edge is more your thing this provides a good argument for the edge pro I reckon.
Oh and this video highlighting what I mean by freedom of positioning and making things like sharpening to the base of the plunge pretty 'easy' https://youtu.be/E1Y6EAHAtEs
For people learning the edge pro I recommend watching through his full videos of 'refining the edge', sharpening the native 5 and the slyz Bowie as it comes with great tips walking you through the process of getting to where you want your edge to go and manipulating the system.
