i have an old straight imported by G.Fralick Wichita, KS. the razor is made in germany. i have honed, stropped, done everything i can and while the edge feels very sharp, it simply will not shave hair! i sharpened it exactly like all the others i have using spyderco stones, red and black strop paste etc. this works for all my others (old dubl ducks, dovo etc), but this thing will just simply not work. anyone else had this problem? do some razors just not do what they should? dont understand how my technique works on 8 other razors perfectly for me, but nothing works on this one. any help would be appreciated!
