Just make it give knife... and no

Edit: It works with knife, I just tested it with this: give_user_weapon( id , CSW_KNIFE );

However, you should prevent the give ammo natives from being called:

give_user_weapon( index , iWeaponTypeID , iClip=0 , iBPAmmo=0 , szWeapon[]="" , maxchars=0 )
{
    if ( !( CSW_P228 <= iWeaponTypeID <= CSW_P90 ) || ( iClip < 0 ) || ( iBPAmmo < 0 ) || !is_user_alive( index ) )
        return -1;
    
    new szWeaponName[ 20 ] , iWeaponEntity , bool:bIsGrenade;
    
    const GrenadeBits = ( ( 1 << CSW_HEGRENADE ) | ( 1 << CSW_FLASHBANG ) | ( 1 << CSW_SMOKEGRENADE ) | ( 1 << CSW_C4 ) );
    
    if ( ( bIsGrenade = bool:!!( GrenadeBits & ( 1 << iWeaponTypeID ) ) ) )
        iClip = clamp( iClip ? iClip : iBPAmmo , 1 );
    
    get_weaponname( iWeaponTypeID , szWeaponName , charsmax( szWeaponName ) );
    
    if ( ( iWeaponEntity = user_has_weapon( index , iWeaponTypeID ) ? find_ent_by_owner( -1 , szWeaponName , index ) : give_item( index , szWeaponName ) ) > 0 )
    {
        if ( iWeaponTypeID != CSW_KNIFE )
        {
            if ( iClip && !bIsGrenade )
                cs_set_weapon_ammo( iWeaponEntity , iClip );
        
            if ( iWeaponTypeID == CSW_C4 ) 
                cs_set_user_plant( index , 1 , 1 );
            else
                cs_set_user_bpammo( index , iWeaponTypeID , bIsGrenade ? iClip : iBPAmmo ); 
        }
        
        if ( maxchars )
            copy( szWeapon , maxchars , szWeaponName[7] );
    }
    
    return iWeaponEntity;
}
