Also shakes head, I must say, I would never 'hope' for anyone to get bitten on the neck by a S calceatum but I guess each one to his own, that was a pretty sad statement and I would hope not many other people on the forum think that way!
Let me say a few things about this whole thread, I have been in the hobby for 8 years now and lost track of how many T's I've handled, it should be over a thousand by my reckoning....
In all of that, I have never been bitten, I have never had a single T get hurt and I have never lost a single one during handling!!
Statistically (0% out of a thousand) that points to more skill than luck in my opinion!
I of course would NEVER recommend that anyone handle a very dangerous tarantula (which the S cacleatum most certainly is) but I have great confidence in my own ability and know the risks very well..... the photos that I take for the tarantupedia don't just happen by accident, it often takes a lot of hard work and time to get them as good as they are, there is often no choice for me personally but to handle them to the perfect pose etc.
Regarding the use of the screwdriver, in my personal experience I find it safer and more effective as a tool for handling or moving a T than a brush, I find that a brush makes my T's more defensive (probably because a natural predator is more likely to be 'hairy') and as has already been mentioned, it's almost impossible for a T to 'hurt' itself biting such a smooth, hard surface in comparison to a brush for example.
I also don't handle nervous terrestrial species in the same way as I did the S calveatum in the video for fear of a fall and injury but this particular species is arboreal.
You can take an Aphonopelma to crickets but you can't make it eat!
