I've got one of the first versions of these - probably about 15 years old, and had a hard life so doesn't owe me. All those cutting of floorboards with a broken off blade. ;-) It's the type with the black plastic 'nut' on the top you pull out and twist until it clicks to lock the blade. But now it clicks when trying to undo it...
Anyone had one apart and know if this can be fixed? And if spares are still available and if so from where (S London). I've got four different Bosch power tools and this is the first one that's broken.
