Anybody tried these sharpeners before?

I have the diamond version of this sharpener - paid $2.99 for it at Gander Mountain. It works okay. They are what they are - rods at a fixed angle - whether they are ceramic or diamond. For them to work they need to be at a greater angle than the existing bevel angle of the knife or you need to remove a lot of steel.

I wouldn't use them on my good knives because I wouldn't want to destroy the bevel angle I put on them with my Gatco sharpener. But for my cheap knives and my Mom's kitchen knives, they work just fine.
 
They are OK but won't put as fine an edge as a real sharpening solution. You'd never get me to run my EDC's through one though.
 
I have a Lansky Quick Fix, Smith's Two Step, and a Rapala Single-stage fine sharpener. These are all similar to the first one on that page.

The fine ceramic crock sticks in these are set at about 23 degrees. They work OK in a pinch.

I wasn't really happy with the results from any of those, so I bought the Lansky Deluxe Turnbox Crock Stick sharpener set. That is giving me better results.

I am also looking at getting the Lansky Sharpening system to provide more options, especially for our really dull knives.
 
I have the Gerber Diamond Pocket Sharpener.

Quite compact, takes up very little space. Mine is currently part of a small emergency kit that I put together for use in a car. It'll put a working edge on a dull knife in short order. If you want a finer edge, you'll need to use a different sharpener.
 
I have one made just like the pocket diamond sharpener (pen shaped.) I don't remember the brand but they can be had at walmart for about the same price as county comm, sans shipping of course. It is defintely handy and I can get a pretty sharp edge with it.

Like Monocrom said It's good for an emergency kit or taking with you when space is an issue; hiking, camping, hunting, etc...

I don't know if the Gerber one is like my walmart one but mine on the other end is tapered down to about 1/16" to deal with serrated blades and has the same "fish hook grove."
 
I have imported about 200 to Denmark over the past 8 yrs. The only complaints I'we had is:

1) When a dull knife is sharpened in the corace slot and the user gets impatient then they press the knife to hard and one of the ceramic sticks gets chipped.
2) When a fileting knife is sharpened and pressed to hard aganist the stiks then the edge gets bent and destroyed.

A tip: Get the knife wet before/under sharpening, then the metal gunk wont stay on the ceramic stiks.
 
I pref a stone to sharpen my knives but on the go things like that are great for a quick sharpen if you are going to cut something tough but small is not a good thing because it is dangerous so I highly suggest you purchase something bigger with a finger guard.

I shop at CountyComm and they are a good site but I would steer clear from a few things on the site. Small isnt always good.

When using those sharpeners I set my finger on the back side of the blade to keep from pressing to hard and just pull 3-5 times which is usually enough to insure a nice edge. More than that and you are going 2 thin and could bend or put in a crack or chip in your blade.
