No - Brainer!
I bought the Worksharp Pro Precision sharpener when it first became available. It has always done an amazing job - especially for those of us who simply Can't keep a consistent angle freehand.
These finer grit stones really make a sharp knife Sharper. As easy to use as those that come with the original kit, they simply snap on magnetically to the sharpening arm and you're ready to go.
I honestly can't think of a way that Worksharp could simplify, or improve this sharpener. I own dozens of sharpening systems. But the Worksharp Pro Precision is the one that stays set up on the table - ready for a quick fine tune or a deep resharpen.
( I DO wish they would give those of us that have already bought the original, a discount on the carry-box/foam upgrade. I feel a bit punished for buying early!)
If you own the kit, you wont be sorry when you start using these finer grit stones. You'll only wish they had been available when you first bought the system!
