  others = 5
}

hook.Add( "PlayerDeath", "ExtraPointsForKnifeKill", function( victim, inflictor, attacker )
  if not IsValid( inflictor ) or not IsValid( attacker ) or not attacker:IsPlayer( ) then
    return
  end

  if inflictor.Category and inflictor.Category == "CS:GO Knives" then
    local pts = ptsMap[inflictor:GetClass()] or ptsMap["others"]
    attacker:PS2_AddStandardPoints( pts, "Knife Kill", true )
