Question: Can this device use the original Edgepro Apex sharpening stones ?
Document: This thing will get your knives sharp. It's a knock-off of the Edge Pro Apex Professional edition sharpener. I hate to buy knock-offs but when the original is $400+ and the knock-off is $40 sometimes you just have to go with the better value.The Good:-Sharpens knives very nicely. Best system on the market.-Regardless of what anyone says I have this version and the the other smaller version and I have no problems with the stones.
Other reviewers have remarked about the quality of the stones. These are OK, but the plastic backing leaves a bit to be desired.The concept, I think is designed by EdgePro but that costs about $250. This is a Chinese knock off but the implementation of the EdgePro concept is quite good. I had previously looked at the &#34;Professional Kitchen Knife Sharpening system&#34; from TomTop. That implementation was very poor and I sent it back.
I would suggest buying a small bag of 60 grit silica carbide (edgeproinc.com offers a 1/2lb bag that is very inexpensive). Get any piece of glass or a flat mirror, sprinkle it with a bit of water, then sprinkle a good pinch of silica carbide. Rub your stones on the glass in a circular motion to flatten them out. This will make them nice and flat removing any bow or  wear from use. This will get you even better results when sharpening.
I would be interested to learn how long others are taking and any other hints.I will probably order some of the EdgePro stones to see how they work.
This unit is not even close to the original. Its a piece of junk and going back to amazon. Spend the extra money and get the real deal, don't waste your time or ruin your knives with this. This is not nearly as stable of a base or even close in quality. The stones are junk and the motion is wonky when raking the blade.
These stones are fine.-Will sharpen knives with wider blades than the smaller version.The Bad:-Fit and finish is bad. Not terrible but bad. It works though. Again, $40 vs $400-The only real complaint is not with the stones but their backing - it's plastic (The Edge Pro Apex uses metal.) If you tighten the stones into the machine too tightly they will strip off the backing and/or break.
And, it keeps your edge nice and even. I am very impressed. ****Many people have posted reviews stating that the stones are low quality. After a good deal of use this is what I have found; the stones will put on a keen edge. The only real issue I found with them is the bow in the center of all of the stones ie.
If you know how to use a tool without breaking it, you'll be fine. I lived in China for a couple years, and the whole country gets by very well on things like this.The suction cup on the base stays put and holds the product steady. Smear a little water on the counter first. The stones that came with the set are perfectly adequate.
It's almost robbery.Go to Congress stones website and buy equivalent grit and size moldmaster stones. High quality hones and they're cheap, about 3 bucks each. Find a metal ruler or something as the stone holder, cut it to size and use an adhesive for them. Then go to town and get a great edge.I'm glad I bought this instead of paying MUCH more for a marginally better version. Hope this helps.
I am a regular consumer of AMAZON, the comments stated below is to ensure problems  don't happen again.Fast delivery. I received the item in good condition, However, it was packaged very poorly. The original box containing the knife kit was damaged and there was no cushion or tie straps to prevent movement of equipment. There was no tape securing the original box. Next the original box containing the knife kit was inserted into another box that was twice the width of the original box and it was packed upside down!
Answer: yes
