The double-ended Park tool was 23mm (TA) and 22mm (almost everybody else), not Stronglight. Stronglight is 23.35mm, and while the TA end of the Park tool will engage the threads on a Stronglight arm, it does not engage them fully and can actually strip the threads in the arm if the arm is at all difficult to break free of the axle. Sutherlands actually explicitly warned about this in their ubiquitous Handbook:

@blackcannon If you haven't found a tool you can borrow yet, when my Stronglight puller comes home (on loan at the moment), I can make it available to you. OTOH, just saw this on Classic Rendezvous:

To remove the crank without buying yet another single use tool, I have used wood wedges (building shims) inserted behind the crank between it and the bottom bracket then gently tap them in. 2 sets are needed opposite each other so you can alternate taps and extract the cranks uniformly. Not much more hassel than finding that stupid Stronglight extractor.

Seems like a cheap experiment, even if it proves unsuccessful.
