Hi,
summary, pull through sharpeners can be useful (best howto below), but dont pay more than $5
Hey guys and gals.
None of these are the one I am talking about. I already have an ACCUSHARP and it works for me fairly well. I don't claim to be an expert at sharpening....nor anything else for that matter. I am just looking for something easy that works well for someone like me that never learned how to sharpen a knife free hand.
What got me interested in it was comment after comment about how awesome it is. Everyone that bought one said it was awesome. I believe the guy said they were $4 each. If you took a flat piece of aluminum and mounted 2 wheels flat on it and left a tiny space between so you could drag your blade thru it, that's what it looks like. They claimed that it beat the pants off the Accusharp and every other one of these drag thru sharpeners that he has tried over the years. I'll try and find a pic of it and post it later so you all will know more about what I am talking about.
NOT saying anyone here is wrong, just trying to get you all the best info so you know know what I am talking about so you can comment appropriately. That's all.
Back later.
Thank you for your time.

Hi,
The rada pull through sharpener is basically like a smooth chef steel,
works for unrolling and realigning an edge, maybe even burnishing a little,
You can accomplish the same using a coffee cup or a plate,
Or if you want to kick it up a notch use the unglazed bottom of a coffee cup for extra abrasion.
Accusharp style tungsten pull through sharpeners are a better deal than rada
but they require a little more knowledge to get the most out of them ,
and most instructions are less than inadequate,
but even those I wouldn't pay more than $5 locally (again),
as on the ebay you can get a tungsten/ceramic/diamond rod sharpener for under $5.
