I have a worksharp 3000 and absolutely love it. I have tried regular stones, diamond stones, grinding wheels, sandpaper on marble/glass (scary sharp system), belt sander......and nothing compares to the work sharp. It will sharpen almost any tool you can think of.
I primarily only use a few chisels which are Sorby skews and gouges and when they get dull about 10 seconds on the worksharp and I am back in business. They keep my skews so sharp that plugs hardly need sanding, and I consistently get nice long shavings.
The 3000 is the higher end unit and a little pricey, but well worth it in my opinion. they make a smaller unit that would do fine but not as versatile.
Christmas is coming
. It is one of the best presents I ever got. I've had mine several years. It is I am sure good for another 10 - 15 years or longer. I haven't even had to replace the abrasive yet. It came with some Norton sheets to start with. They seem to last forever.
