a brick is not a hone.
and anything coarser than 4000 grit or ultra fine is not advisable for use unless you are restoring or setting a new bevel.
Norton 4000/8000 are good starter hones, and will last you a very long time...
and blue and yellow coticle stones are very very bad ship them to me so that I can properly dispose of them.:w:D
