Rimnshvstr8,
Thanks for the reference and word of caution. I'll be sure to pay attention and avoid the higher pitched sound, if my edge sharpness starts to fall. But in my case, I think the duller sound indicates that only the first bevel is making contact; the higher sound, the second bevel (the real edge). I double taped the spine today, and stropped with no problem at all. HHT worked, and the shave was great. Seems to confirm my double-bevel suspicion. Nonetheless, your point is well taken! - Bill
