The Ninja Foodi NeverDull Essential knife set is a pretty decent knife set.  It is a 9 piece knife set with block.  The block has a sharpener that is a fine rolling sharpening stone.  It will keep your knives reletively sharp for a while but if they go dull it will take more then that to re-sharpen them.  The knives straight out of the box are sharp and have kept thei edge for the last month or so.  over not a bad set.  Would make a nice starter set for someone getting their own place for the first time.
