Unsharpened Sgian Dubh

[bjproc]

I know you need at least an eight inch better ten inch wheel to sharpen a chizel, but wouldn't a smaller wheel work alright for a dub?

i've sharpened plenty of chisels & plane irons on a 6" wheel.

slow wheels (water fed) gives a good non-burnt edge, but still need to be sharpened with a hone
