got a hone from invisible edge Chinese 12k grit hone
Although new to Sr's took the edge off the shave ready one i had bought by buffing up the blade after taking it apart to replace the scales.With the use of above hone and home made balsa strop with red and green paste on it brought back the edge a treat.In fact the first shave after touching it up was the best so far,out of the 8 i've had!
