Honing hard steel razors and russian razors

[RusenBG]

Hi guys i have a question for the old and experienced honers . I have some dificultys wih the very hard steel razors and especialy with the russian blades . usualy when i hone a razor , the edge gets fantastic , very sharp and very smooth .This is with most of Solingens and 90 % of the razors .
Still the russians straights make me mad as i cant get that fantastic edge on them watever i do on the stones .
Ive read some hide statements that there is a trick or something that is specifis to deal with those razors and the tuff steels , witch are hard to hone .
Please if you have experience , share it .
