Recently Got my Edge Pro in hopes that I could learn to sharpen knives. Watched a bunch of videos and tried out a couple cheap old knives and then ventured out to sharpen my ZT 0566. This was my first complete sharpen and polish. What do you guys think?

looks ok but it looks like the edge starts thin and gets broader as you go towards the tip,there is a method to avoid this.Go to youtube and watch some of apostleP's videos,he is a big fan of using the edge pro.Really nice guy and good teacher in his videos.
 
Just from the image, I feel that the apex has not been polished. Or, did you put a micro bevel?

No Micro bevel. That pic is not doing it any justice. For some reason, Photobucket is not allowing me to access my photos and I have a few more that show the mirrored edge alot better.
 
If the edge is polished to the apex, you have done a good job! What was the finish? Polish tape at #3,000?

Looks good ... for a beginner. ;)

In addition to the critiques already offered, I still see scratch patterns along the edge that would not be visible on a mirror edge.

^^^ This.

The top (?) edge of your bevel (furthest from the cutting edge) has scratches. This is a classic rookie mistake. Well, at least, it's one of my classic mistakes. This comes from your first stone being a shallower angle than the rest of the stones you used. Since the media of the course stone is so much... coarser... bigger... it's up higher off of the stone ever so slightly. When the next stone in the progression is used, if there is even the slightest change in the angle it will then miss these scratches because the media (stones, diamonds, etc.) isn't as course (so shorter).

Make sense?

I could be totally wrong, because I'm still a newb to the Edge Pro and its clones, but it seems like a reasonable explanation.


Now on to the important question... is the knife actually sharp or just pretty? Ha!


(By the way... every picture you've like ever taken is available to be viewed, might want to lock that down)

I appreciate the feedback guys. I am still learning and really want to become good at this. What are some tips? I basically Sharpie the edge and find the right angle and keep the angle set the entire length of the process. 220, 400, 600, 1000, 2000, 3000, and have some 6000 tapes in the mail.
But yes, the knife is super sharp.

I have a kershaw shuffle that I am trying to experiment with and want to try my trial and error our on this knife.

What I want to understand, is how can you have 20dps on a knife if the angle of the original edge is 24 or so? Work your way down as you re profile?

I have had some good discussions on Edge Pro sharpening recently. FYI.
http://www.bladeforums.com/forums/showthread.php/1450834-Edge-Pro-sharpening

Since then, I have obtained diamond stones for reprofiling, which replaced the stock #120 stone. The Edge Pro 120 silicone carbide stone is OK but thins pretty fast. Though it might be sufficient for 8Cr13MoV.

Common issues I have had with Edge Pro sharpening so far are:
(1) Stones not being flat. You can correct this using silicone carbide powder on a glass plate (Edge Pro provide them in their stone flattening kit).
(2) Stones with different thicknesses. If your #400 stone is thinner than #600, for example, the #600 stone may not grind the very apex because a thinner stone makes a deeper angle than a thicker stone. You can correct the angle using either a correction collar or an angle cube (or grind them to the same thickness).
(3) Knife not being held consistently. This also makes the sharpening angle inconsistent. Convex or Hollow ground blades are little bit difficult to sharpen on Edge Pro for this reason.
(4) Foil burr or wire edge not being removed. Because it is very thin, the edge with a foil burr may feel very sharp. However, it deforms easily, and the sharpness is gone just with a single cut into cardboard. There are a lot of discussions on how to remove it on the forum. You may want to review them.
