I have owned a couple of the Blackbirds, but they were the HO version. Very nice sounding cartridge, reminded me a lot of my ZYX, similar kind of voicing.
As I remember the wires are pretty well protected by a channel guard. There are not flying out there in open air like the Benz Micro Glider. Owned a couple of those too, never knocked the tip off them either.
Currently own an Ortofon A90 as one of my cartridges and it has that same type of design. No accidents here, and owned it for a few years.
You have to use common sense, be aware of what you are doing, and treat your turntable with respect. They are not for everyone, as the ham handed will damage them. But if you have some self awareness this does not have to be the outcome.
When I was young I damaged a couple of cartridges, but it hasn't happened in a lot of years. And I prefer to install my cartridges without stylus guards, as those can be difficult to manipulate. Or I have had more than one cartridge have those missing. The one for my ZYX is an absolute nightmare and difficult to install or take off when its bolted to its box, much less a tone arm.
Blackbirds are nice cartridges. I have always wondered who designs and builds them for Sumiko.
