I found this warning on our Dutch Harmonica Forum today, the poster is a well known Harmonicaplayer, so I take his message very serious.
It have nothing to do with me being a Suzukusucker ;D
I used Google translate so perhaps there are some wrong words in it.
He was trying to make the Hohner Bluesband harmonica’s, bought as a set of 7 in Norway, playable for a friend.
To my horror, I next encountered, and pay attention now, these harps are harmful to your health!
The reed tongues are often tuned at the factory, (in order to sound in the right pitch) but it is so rude and inaccurate done, that the reed tongues had metal lying around on them, like a kind of curled splinters “that loose as soon as you touch them”.
Result: if you play the harps and you suck / breathe in, this sharp metal splinters directly go into your lungs!
These pieces are 1 millimeter and larger.
I have opened several harps and on 4 harps i found these pieces of metal.

So just beware of cheap new harps, first tap them out firmly before you even try to play. It good be a problem to other low cost harmonica’s as well, but hopefully it is just a incident!
Have Fun, John
