Looking for some information on a German Hoffritz razor (closed comb, non-slanted version). Are they basically just an older rebranded version of the 34 HD (made by Merkur) or do they predate Merkur? I have heard they were adjustable (similar to the Progress), is this true? Does the aggressiveness of the Hoffritz shaver differ significantly from the current Merkur 34 HD? Thanks.
