Hi André,

You must be feeling good that that the world is 
finally rediscovering old world hammer felts by 
Filzfabrik Wurzen.  You've been ringing the 
Wurzen bell for some time now.  It's all very 
exciting!

An important component of the Wurzen felts, or 
any old style hammer felt, is the cold pressing. 
In the New World, Ronsen has been a Rock of 
Gibraltar in providing the cold pressed option 
since I first discovered them in the '80s.  I 
know that at least one big European hammer maker, 
namely Abel, is now providing cold pressed 
hammers as a stock item - with their Natural 
Felt.  This is a new trend... is Renner cold 
pressing for you?

(My apologies if this subject has already been covered in past posts...)

Best,

David Stanwood
