EdgePro copy sharpeners

Good point that the difference in price with the KME is not very big.

What weaknesses do you see in the design?

Not inherently stable (need to bolt or clamp to workbench vs. flipping a suction cup lever).
Stone looks very short (OK on small knives, but hard to hit full blade in a single stroke).
Clamp is very narrow (unless it really locks onto that blade, it might be easy to knock it out of alignment).
Golf ball handle for stone is in wrong place. Should be at the "open" end of the stone.

I DO like that ball-end that they use for the rod. Very little chance for slop there (as long as the tolerances are good).
But honestly, it's little more than Lansky attached to a base.

At this point, it seems anything new is going to take the core idea of a movable stone that can have a fixed angle of traverse.
Clamp the blade, hold the blade, magnetically grip the blade, you're still going to slide a stone back and forth.
Maybe the next real innovation will be in the sharpening medium?

First of all, it does not offer any improvement over existing systems which have proven designs and customer support so that alone would make it redundant in my opinion.

But besides that.....

Not very stable
The clamp does not have any provision to make sure that the blade is clamped at the same position each time like for example the depth key of the Wicked Edge.
The clamp is tightened with just one screw and I think it will only work well with some knives.
I do not like the rotation system of the clamp
Can only use proprietary stones and just a few types will initially be available

In fact.... the only thing I do like about the design is that they use a ball joint bearing.

Saw the Viper on kickstarter as well. Stopped reading when I saw their claim of innovative and great design.
Also as others have said not really better than existing and proven designs.
