Hello,

Newbie here. Just picked up a few of my first knives:

KaBar Mini FK
SOG Mini X-Ray

I also bought a sharpener that looks like this:

It has one notch where you slide the blade through ... I've done this to both of my knives. It seems to have put a sharper edge on the kabar and mini x-ray but it's hard to tell because the xray was sharp to begin with.

It didn't come with directions or specify which way I should be sliding it. I bought it on vacation at a hunting store.

Anybody want to comment? Thanks
 
I'd get a sharpmaker if I were you. Or benchstones if you know what your doing with them
 
I agree, definitely get something better it may make them sharp but it dosen't last and you will have to resharpen fairly often, in a few months to a year of use your knives will look like a boomerang.

To use the sharpener pictured, Hold the knife handle with preasure down, cutting edge faceing up on a bench and draw the sharpener from heal to point about 3 to 4 times. I would only use this on my cheap cheap kitchen knives if i had to.
 
i use one of those with no problem at all.ever so often shoot a drop of oil on the tungsten cutter.
 
i use a set of wheels to sharpen knives with. i have been sharpening knives for about 24 years and for 10 of thoes years i used an ez sharp system which is similar to the lansky. the wheels can put a razor sharp edge on a knife in no time compared to the other systems but it takes practice to get good using them. i watched the guy i bought my first set from for almost 8 hours at a gun and knife show. then i practiced on a hacksaw blade until i had it down which took a few days of practice. they are all good systems but i wouldnt trade my wheels for anything else.
 
Thanks for the replies. Here is the exact one I bought

Do I bare down hard with the sharpener? Or use it lightly? Thanks
I understand that I go from the base of the blade to the point, but which way do I hold the sharpener? Does it matter?

I'm sharpening a X-Ray Mini (which has small amount of blade + tanto ATS-34)
It did my ka-bar up real nice though
 
light pressure only

doesn't matter how you hold the sharpener sol long as your fingers can't slip onto the blade.
I can't think why going from point to base would be worse then base to point either
 
thats not the ez sharp. the one i had was a clamp that held the blade, similar to a lansky. it had a guide that clamped to the back and 2 slots that a rod passed through which had 3 stones on an aluminum block. you chose which angle you want and start moving the stone across the blade until you work up a burr, switch to the other side and repeat. i finished the edge off with a single ceramic stick.
 
Aww man, once a thread like this is moved, there will not be anymore responses...

Just like mine the other time :(
 
I really don't recommend this type of sharpener, for a couple of reasons:

1) The carbide cutters tend to snag on the larger carbides in some blade steels and break them out of the steel matrix instead of wearing them down to form the edge.

2) The relative motion between the cutters and the blade is parallel to the edge. This means you are cutting microscopic grooves in the edge bevel which will act as stress risers, weakening the edge and allowing it to bend or break away. With a whetstone, you still cut grooves in the edge bevel, but they are perpendicular to the edge, so they act as micro serrations.

Think about a piece of corrugated sheet metal. If you run the ribs parallel to the ground and push down, it flexes and bends very easily. If you stand it up with the ribs perpendicular to the ground and push down, it is very rigid and will not flex or bend easily.

That is why the edge you put on with those pull-through sharpeners never seems to last long. I wouldn't use one for anything but emergency field touchups.
