I admit I am new. I use a TM 3" latigo. I have been stropping for a month or more. Recently i find that my razor "sings" when I strop. The problem or not , is that to make it sing it feels as if the spine is ever so slightly raised. May be my imagination. Now it won't sing every pass but more and more it does. Oh my 6/8 sings easier than my 5/8. Interesting. Is this a good technique to get your razor to sing while stropping even if the spine is ever so slightly raised?
