Need variable speed belt grinder?

[SHARPCO]

For light-duty work, the WorkSharp Ken Onion Edition with Blade Grinding Attachment is a convenient and capable low-cost option which offers variable speed.

Hello Cyrano. 

I sharpen knives with Tormek and Work Sharp Ken Onion Blade Grinding Attachment. But I need belt sharpener that has platen so I ordered Viel S-5-M. The Work Sharp BGA is good personal sharpener but I have to use better machine because I'm professional.
