Mandolin slicing blade?

[mysharpener]

I have a restaurant owner who's asking if I can sharpen a madolin slicing blade.  Their mandolin looks like this:

I know I wouldn't do the grooved blades, but the straight slicer?

The straight blade shouldn't present too much of a challenge.  Match the bevel carefully, grade your stone carefully so that the cutting action is very controlled and watch your progress closely.

Those blades are so delicate I would not attempt it with anything other than the SJ 250 or equivalent. Keep in mind that there is little margin for error on this device. you could easily change the cutting angle, cutting edge or who knows. In fact, as a beginner I would leave it alone. Speaking for myself of course.
