Ok, may I put some comments?
First problem -- we have Russian knife laws. The worst part of them are called GOST's (State standarts) and are real pain under the tail. If shortned they mean that your blade should either be under 90mm, or be thinner then 2.4 mm, or knife must have no hilt or deep finger grooves. Or you must haver firearm license to buy one.
Problem two -- majority of sales are made to people, who don't want to spend too much. Result -- not too good.
Now to companies.
SARO -- foget them. Things can be worse, but they'd rather not. Poor steel (something like 425) Interesting, yet not too functional desighn, and poor quality.
Southen Cross -- Have good reputation. Well-desighned, fine steel.
ROSorujie -- Another good brand. Solid, old-fasioned, well made. I've got their damascuss blade and pleased.
NOKS. Controversial. Really. It has some fans, yet many people curse it. It's nearly only company wich makes "tactical"-styled knives. Won't lie, being original is not easy

. The most common problem -- QC and prices too steep for their quality.
