If you want to sharpen your own knives, rather than rely on the service that you seemed happy with, my best advice would be to first learn the theory behind sharpening knives. Any sharpening system will work well, if you know what you're doing. Any system can fail to give your knives a good edge if you don't know what you're doing.
It will help you if your know enough about your blade geometry and steel type to choose an edge profile that best fits your needs. So you may need to reprofile the edge and then settle into a sharpening system to maintain a sharp edge at that profile.
One thing to remember is that no one here can guess what will work best for you, just as we can't guess what knife you'll like best. Some people prefer to freehand on expensive or inexpensive stones, others prefer guided systems, others prefer power systems, such as paper wheels, belt grinders or the WorkSharp.
Freehanding takes time and practice to do well. Guided systems, such as the EdgePro or Wicked Edge, can produce incredibly sharp and properly profiled edges, easily. An inexpensive Sharpmaker can give you good edges if your edge profile matches the stone angles and you know how to raise and remove a burr.
I personally, like the Wicked Edge system, backed up by a Sharpmaker for quick edge maintenance. Others prefer the EdgePro, which is also excellent. The Lansky can give very good results, and is a lot cheaper, but it won't match the Wicked Edge or Edge Pro.
It's easy to tell you a system that can make your edges very sharp, but it's impossible to tell you which one you will like. I had an Edge Pro for a short while, and while it is an excellent system, it was too messy and required too much maintenance for my tastes. But for lots of people here on the forum who really know their stuff, the EdgePro is what they prefer. Personal choice is extremely important, but not predicable.
Lots of threads here on sharpening. You'll want to know how to reprofile an edge, which means deterring what the profile angle is. You'll want to know how to raise a burr the full length of both sides of the edge and how to remove it. You'll want to know how to recognize a burr. You'll want to know whether to add a micro bevel.
We have thread after thread asking what's the best system to buy. Invest in yourself first, by which I mean learn the basics of the art, then invest in a go-to system.
