When it comes to knife sharpening I've been up, down & back!! I have tried many of the store bought knife sharpeners, many of the systems sold on websites, and everything in between. A bunch of years back I decided to master the
art of properly sharpening knives without ruining them or prematurely grinding away metal.
I purchased 3 high quality Arkansas Stones 2" x 10", one medium, one fine and one extra fine and a quart of food grade Norton Honing Oil. It took me hours and hours but one day t just clicked in! I can now sharpen any knife shaving sharp in no time at all!
For Kitchen knives I use the Fine Stone to quickly bring back a very sharp edge unless my wife has really dulled them. For Workshop and garage knives I just use the Medium and for my good pocket knives, vintage fixed blade Scalpels, Hunting knives and tools I use all 3 in progression.
It takes commitment, patience and perseverance BUT once you "get it" it stays with you and knife sharpening becomes a snap!
I have NEVER found any electric or store bought sharpener that was worth anything and if you have fine or expensive knives I'd NOT want to ruin them in such a devise. BTW, sharpening knives by hand is not only highly effective & efficient, it will also allow use of your favorite knives for lifetimes to come since it won't waste the metal by unnecessary grinding.
I suggest looking into Arkansas Stones and check out Dan's Whetstones website (I am not affiliated with them in any way). They have excellent Stones and the will last your lifetime in normal use with proper care.
I have also followed the same path sharpening Drill Bits. No more Drill Doctors or Jigs that never work very well. I do them by hand on a Bench Grinder checking my work with a Drill Gauge. At first - very awkward, but after a while it becomes pretty easy.
