Are pull-through sharpeners that bad?

    I haven't seen one thread recommending these types of sharpeners. Are they really that bad for putting an edge on a knife? Are the other options really that much better?

    I found a SOG pull-through sharpener for cheap, is it crap?

    Would you classify the Spyderco Sharpmaker as "pull-through"?

    They're good for touchups and nothing else. The ceramic ones would be my recommendation, while the carbide ones will chew up your blade.

    I personally don't find any use for them, as I've never managed to dull my edge that significantly in a single day of use.

    yes. . . Unless the intent is to mangle your edge, then they are wonderful.

    No, it's a sharpener you use by coming down on the rods, you don't merely pull it through straight at all.
    This is a "pull through" any of the rod in block sharpeners aren't.

    yes. they are built to be idiot proof. it is really simple, but it takes a ton of metal off. probably good for reprofiling.

    Personally, I wouldn't even go that far. The angles on these sharpeners are so obtuse, you'd be doing yourself a disservice.

    An emergency field sharpener is about all they're good for but there are much better options for field sharpening.

    Reprofiling is usually done at a thinner angle, the pull throughs tear tons of metal off the edge at a blunt angle.

    You see a lot of people using the pull through in kitchens. Where the knife wouldn't get any sharpening unless it was something simple and quick to use. I haven't seen one yet that would give a satisfactory edge, so I think they are nearly useless.

    I use them for my kitchen knives. I use the Chef's Choice Commercial to get my primary edge, and then use a pull thru whenever it starts to dull. This system works very well for me.

    Those sharpeners are great at ruining blades. Typically what some of my friends use, followed by me fixing it. I would recommend a sharp maker or something similar. You have more angle options and alot more control over the results.

    I only use them from time to time on my cheap Friends knives that are soooo screwed up they give to me to fix, they are thrilled with the so-so results that I give them. I would not use them on my personal blades, but I know how to take care of my tools.

    Those electric "sharpeners" are even worse than the carbide notch type.

    They are great if this is how you like your edge.

    OUCH! I think this picture pretty much sums up the answer. :D Thanks, everyone.

    Ive found that the Benchmade sharpeners aren't too too bad, I only use it for very bad edges and I find that I can do better work with tips on my sharpmaker after I use the pull through, I don't have a nice enough camera to capture the edge it puts but yes it does take off a lot of metal.

    I hate carbide pull through sharpeners with a deep and abiding hatred for what they do to an edge.
