is the lock ring steel of some kind of ally? most are steel. sometimes on dutch bikes they're plastic and you have to go to someone with the correct dutch bike tool, but it doesn't look like it's the case here.
tapping the hook bb tool with a rubber or wood mallet often does it. the hammer and screw driver meathod does work but it will damage the lock ring inserts the more you do it. i use that as i last option.
