carbon nano tubes / cutting steerer
I'm about to cut about 5mm off the steerer on my Look HSC5SL fork. I know I have to use a special untoothed hacksaw blade. I've heard about the potential health risks from carbon nanotube dust, and while I'm not going to get in a panic about it (I'm sure any risk from a single exposure is tiny) it doesn't do any harm to be careful. Any tips in this regard? Wear a mask? Do it under water? 
On the other hand, perhaps the HSC5SL doesn't contain CNTs anyway, as it is a fairly old design? I know the dropouts at least are "Very High Modulus" but I think perhaps they predate the use of CNTs in bike frames & forks. Does anyone know for sure?

just a silly question - what are you on about?0

Easton use CNTs. Just tape the area to be sawn with masking tape to stop the fibres tearing and saw with a damp blade. Hoover up all the dust, even wear a mask if you're worried.0

Thanks for the tips.just a silly question - what are you on about?0

Dissapointed....I was thinking this was going to be a discussion about Buckminster Fullerene atc.17 Stone down to 12.5 now raring to get back on the bike!0

Well, we could start..
Apparently carbon nanotubes are just buckyballs extended into tubes, with a semi-spherical half buckyball at either end. I thought that was pretty cool.0 -
Take the tape and wet blade precautions, but have somebody else there with a hoover at the same time working as a form of extraction.......0
