I got myself a carbonsong Thiers 5/8 a few weeks ago .
Thiers recommend their own graded Diamond Pastes in order to get the best out of this new steel .
I have been experimenting with my own hones at the moment & I have found that this steel responds very well to the Spyderco homes I own.
This week I decided to go back a bit away from the spyderco ultrafine hone.
I took the razor to the fine hone to give the edge a bit more bite & I must say that the edge it has given me is a great edge for me.
I have used it for three shaves so far since this & the shaves are great.
So I will continue with this for a while but this experiment may help others who have had issues with the carbonsong blades .
I will keep posting my own findings with this.
Cheers Paul
