The Edge-Pro uses a continuously adjustable angle adjustment. With an angle cube, I can set the angles to previsely 12.5 or 17.5 degrees or any other angle.
You can do the same with the WE in a couple of ways... either by turning the angle bar around, or using the screws on the back side where there's no indents. I think a better comparison... you can achieve lower angles (below around 12-13 deg.) easier on the EP than the WE.
There are far more useful accessories available for the EP. From el cheapo stones to Shapton Glass and Chosera, ATOMA diamond, DMT diamond to polishing tapes and Kangaroo strops that fit the machine.
These same accessories are also available for the WE (probably from the same person you're getting them from for the EP).
I only need one stone per grit with the EP. The WE requires two, making extra stone grits twice as expensive.
True... although you get twice as much which should also (theoretically?) last twice as long. But the initial cost is higher, as well as the cost for most accessories.
By holding, rather than clamping the blade on the blade table, I can move it around, compensating for curvature and getting excellent results on the tip.
The flip side... there are some users of the EP who have found it necessary to clamp the blade or have installed magnets to hold the blade. But for the most part this is true... although you can set up the knife in the WE to correctly sharpen the tip, it is easier to adjust the knife on the EP. You do have to take greater care not to scuff the sides of the knife on the EP vs. the WE, since you can move it around.
Long blades require re-clamping on the WE, but the EP allows you to just slide it along, maintaining the same angle.
The WE will sharpen a 17" long knife without moving, which should more than cover the majority of knives most users have. BUT, you do have to set the knife for the tip area, so it can be a bit more limiting... but will still cover most knives.
I've used both extensively. They are BOTH fine systems. I would never "bad-mouth" either of them.
Me too, and I agree with this. I think the comparison should be made more on cost - the WE costing more (especially the initial outlay), ease of use - the WE has a shorter learning curve, and is a bit simpler to use, speed - it's quicker to work both sides of the blade at once. I think portability might also be something to consider... the EP is easier to tote around and setup/teardown.
But after use, I find that the EP fulfills my needs better, and IMHO is far easier to use, and more economical.
