Amazon has the Gatco 6402 sharpeners for $1.83!Yes the shipping is $5.98 but all together that's still well below the regular price.My last one lasted many years.

That is a good deal. I've got a lot of knife sharpeners, from electric to Lansky to a lot of stones.

Don't use most of them, what ever is simple tends to work best.
