any slant razors not made by MERKUR

and are they for sale anywhere ?

I'm no expert on slants (I only own one -- a Hoffritz travel model), but most of the slants that you see (Hoffritz, Pomco) are just vintage, re-branded Merkurs. I'm sure there are a few out there that were not manufactured by Merkur, but they are the exception. To my knowledge, there are no current-production slants made except those by Merkur.
