I have not got a narrow hone so i have started with 1k norton to get this bevel as level as pos and i have litterly used the last inch of hone and imagined it is narrow. Using x pattern and reallyrocking or rolling stroke and marker test quite often took my time and the bevel as come up a treat right from the heal to the toe there is still a slightly thinner part on one side but the bevel panes are bang on . i have oviously moved up grits 4k 8k and bbw plus coticule and i have to say this ti is now an exallant shaver infact i would say the feel and shave is to me is perfect. Thanxs once again for the advice and it least i no how to tackle a warped blade.
