First of all, sorry for writing in English. I understand a little bit of German but I can't write it myself.
So I am a drummer from Bruges, Belgium, who also hammers cymbals by hand.
I started doing this about 20 years ago, after a long unsuccesful search for cymbals that would match my taste for really dark complex cymbals. No modern factory made cymbal could satisfy me and I couldn't find any old K's.
After some years of trial and error I started to get the feel for it and acquired the ability to change a cymbal to a pre-determined sound.
The cymbals I've hammered can be seen and heard on my webindex page. Mind you, I have hammered most of these cymbals to suit my personal taste (dark and trashy) but I can also brighten the sound or raise the pitch with a different hammering method.
I hammer pro- and also some non-pro-level factory cymbals into much richer sounding cymbals.
Besides creating light complex jazz cymbals, I also hammer heavier rock-oriented cymbals to dramatically enrich the sound.
Some "before and after modification" files can be heard HERE.
Some student cymbals I hammered into professional cymbals can be listened to HERE.
Soundfiles of these next cymbals can be all be found on the site.
This was a Paiste Signature Power ride, hammered to sound like the old 60's Tony Williams ride, but a little heavier:
This was a Zildjian ZBT 20" ride, now a very complex thin professional jazz ride.
This dark complex sounding ride was once a bright Paiste 2002 22" ride:
A 20" Tony Williams (Nefertiti) ride made from a Sabian AA:
A 20" Complex Dry Crashride made from a Paiste 2002:
A 20" Dry Complex Rough Ride, originally a Paiste Dimensions:
Finally a "before and after" pic of a cheap 16" Headliner crash cymbal, now a professional dark thin crash:
