Should it increase once or everytime when kill knife ??

You could look this and remove "health gaining" by set cvar to 0
[CSS] ES->SM "Knife Gaining" request

One current round

And if you done two kills with a knife in a row, increasing the speed will be doubled?

Example: one kill — 1.3 speed, two kills — 1.6 speed, three — 1.9 speed etc.

If you mean that plugin what I posted, no.
It set speed when get first knife kill in that round.

You can do that speed for one kill was 1.3, for two kills in one round in a row - 1.6, for three kills in a row - 1.9, etc.

Here
added new cvar
knife_speed_increase_percent "30"
and change two other cvar by default
knife_health_gaining "0"
knife_speed_gaining "1.3"

PHP Code:

Thank you very much.

All works fine, but the speed increases even if to kill a teammate =)

Please also add the output to the chat messages:
one kill - [SM] Your speed increased by 30%
two kills - [SM] Your speed increased by 60%
three kills - [SM] Your speed is increased by 90%
etc.

[Bacardi]

updated.
it will show firsts lower speed percent from chat less... example player get speed 30% but show it 29%
but when percent value get bigger it show right

[cssnik]

You can change a little — in the first kill with a knife - increase speed by 30%, and for each subsequent kills increase speed by +10%, i.e.:
one kill - [SM] Your speed increased by 30%
two kills - [SM] Your speed increased by 40%
three kills - [SM] Your speed is increased by 50%
etc.

[Bacardi]

Try
knife_speed_increase_percent "10"
