i just started using one of these. WOW! nice system :thumbup:

got a quick question for y'all who have been using one, already: it's pretty simple when a knife has a full flat grind, but if it has a saber grind, which portion is supposed to lay flat on the little table/tray? the portion of the blade that is ground? or tilt it and lay it flat on it's grind?

i'm guessin the part that is NOT ground is what i should be trying to keep flat, right? i mean, as long as there's enough of it there for stability, right?

You've got it!! :thumbup:
You want the knife to be stabilized. If it is, you can set any angle you need with the guide arm.

cool, thanx guys :)

i'm really liking the EP, finally worked up (after several knives) to doing my Rodent. it's still far from a simple job (for me), but the EP makes it more doable and consistant than anythingelse i would've used for a blade that size.

here's one odd thing that came about, though: the Rodent Waki is full flat ground, so there wasn't any deviation between the areas i was asking about resting the blade on. however, after i finished, i noticed that the sharpened area was a little wider on one side than the other. i used the exact same angle (obviously) on both sides. could this have something to do with the way the blade was ground? i don't count strokes (like on my Lansky), but i'm having trouble believing i spent so much more time, on one side, that the bevel(?) would be noticably wider on one side. what could cause this?

thanks
 
the bevel may look taller because the grind wasn't as deep as the other side of the knife.

This is a common problem I have with the EP on most knives, FFG or not. The only knives not susceptible to this issue are the ones with a large flat 90 degree angle on the blade, or the ones with blades so thin that you wouldn't notice any wider edges on one side. Despite how perfect it looks to the eye, even a deviation of a few degrees on one side would cause this issue.

Because of this, I have a newfound appreciation for my paper wheels and vow to practice on them more so that the edges on the wheels look as pretty as the edges off the Edge Pro. I'm getting fairly good, and I think I'm just about ready to work on knives with coatings on them:thumbup:.
 
Another possibility might be the angle you are stroking to blade on one side vs the other. I'm referring to the angle the stone arm makes in relation to the knife platform. When I sharpen, I'm very careful to keep the stone arm right in the middle of the platform for every stroke. If I move towards the corners of the platform I notice a difference in the bevel. For uniformity, I keep right in the center!
