>Joe, I've got a Oneway system with the #1 and #2 knives and it works well. That said, I've also watched Bill Grumbine core with the McNaughton and he sure did make it look easy and a number of folks at his demo tried it as well and had no problems. I wish I'd taken the offer to give it a try at that time.

The Oneway has removable cutters that can be sharpened and replaced at about $30 so you may wish to examine the sharpeming process with other tools.

Still, Russ has given as good an answer to your question as there is.
