After years of on and off trials to learn free hand sharpening (and still trying) I find I almost always revert back to my Lansky system. It seems like this is the only way I can keep a consistent angle and get reasonable acceptable results. I need to replace two of my Lansky stones but when I went to a local outdoor store, they had the KO on sale. For about $65 more than my Lansky replacement stones, I could get the WorkSharp. I am asking any of you with experience of one or both systems, do you think it would be worthwhile to upgrade and go through another learning curve ( lots of kitchen knives to practice on 
). Thanks.
