Great deal on knife sharpeners

Do you have a knife sharpener in your prep supplies?  I had an electric one.  No use in a big emergency.  And we may be using our knives a lot!  Recreation Outlet has these ceramic knife sharpeners this week for $1.99!
Ok these probably aren't as good as more expensive ones.  But if you don't have one, go spend $2 until you can get a better one.  It will sure be better than nothing!  I know from butchering my rabbits how quickly the knives get dull, & how big a difference a sharp knife makes!
