I got a sharpmaker for the first time and followed the directions and realized that 2 things aren't clear in the directions: Does it matter which flat side you use? and does it matter which corner you use? I use the corner between the flat sides and use any flat side that comes first.Am I doing this wrong? Plus I went back and back beveled a 1095 old hickory kitchen knife to 30 degrees then hit it on the 40 degree side 50 or 60 times per corner/flat on the medium and fine stones.Did I do that wrong? The knife feels sharp,sticks to my finger nail, but will not make a clean cut on paper.No matter what I do it has a wire edge.What do I do about that? or is that just a thing with old hickory knives?

Just use the side that's cleanest. And switch when it gets dirty.
Try using very light pressure and see if that solves your burr-problem.

It's kinda floppy but some what strong.I will run it down wood and use the fine side again tomorrow and will post an update to see if that fixes it.
Does the burr just flop around from one side to the other when you alternate strokes?
No,it's consistant.I'm starting to think that when switching from back beveling at 30 degrees to the utility edge at 40 degress I didn't take enough time to hone it.I'm going to try the wood and then hone it alittle more.If that doesn't work I'm just going to leave it be until it dulls and pay more attention next time.

If the burr is on one side, and doesn't change to the other side with a stroke or two on the side with the burr, you are probably not holding the knife straight up and down. One helpful trick someone came up with (and I keep passing along) is to prop a mirror up behind the SharpMaker so you can see the reflection of the knife and your hand as you make each stroke. You might be surprised at what you see.
From what I have seen with the SharpMaker, forming much of a burr is usually a sign that you are using way too much pressure. It only takes a few ounces of pressure to remove steel, especially when using the corners of the stones.

I say it's a pressure thing. The Sharpmaker is the system that taught me pressure DOES matter. Don't remember ever getting results like yours but I did form a few very small burrs and my edges did make leaps when I slowed down and lightened up on pressure.
As a point of reference I use progressively fewer strokes and progressively lighter pressure until I'm alternating left side to ride and basically just letting the knife balance in my fingers and slide down the rods with it's own weight.
Yes, probably lighter than necessary.
Yes, it works for me. (no burrs)

Update: Took everyone's advise and used it wisely and I have no more burr.It's not shaveing sharp,I can't sharpen it shaveing sharp due to my mom haveing problems with blood clots and thick blood so she is on blood thinner and can't get cut or she will bleed really bad so I put a safe edge on it.Sticks to the finger nail,cuts paper,but is not scary sharp like some of the higher end knives such as spyderco.Thanks for all the advise guys!!
I find super sharp cuts heal faster and hurt less, the cut usually only feels like a needle prick and it stops bleeding much faster than cuts with my knives that are sharpened with a low grit.
