frustrated with e.a. berg 4/8 frameback
I'm on my third? failed attempt to hone this razor. Three times now I've honed it up to where it's just barely shy of shave-ready, then bam. The thing's dull as a butter knife. Happens about the time I start fine tuning with diamond on felt. I haven't had any problems with any of the four other razors I''ve worked on since I got the diamond. Seriously, it went from almost there to blunt in maybe five laps on the felt, and that's after 10 laps that made a noticeable improvement in sharpness. I'm not using any pressure to speak of and I've tried to be very careful about keeping the blade flat. I don't think I'm rolling the edge or anything, so what n00b mistake am I making here?
Any help would be appreciated. For some reason I've taken quite a shine to this little thing and would like to shave with it.
