it took me forever to find this for my gamemode "Haunted" you want to change from "knife_held_mp" to "knife_mp"
call it like this
self giveweapon "knife_mp";
as for the camo and the glitched knife at the same time do it like this then
self giveWeapon("knife_mp",0,true(38,0,0,0,0));
See Where the "38" is you change that to change the camo. all the camos go from like 1-50 depending on how many camos are in the game.
go to create a class and go to put a camo on your gun, and count from the first camo to the camo you want so say if the camo is 3 camos away from the first you put 4 instead of 38.
1 is dev gru and 15 is gold thats all i can remember.
Hope this helped
