After looking for vintage razors on ebay, I called up my local antique store.
lo and behold, he was selling Solingen razors by the half-dozen, all for 8-22 dollars.

I purchased this King Cutter for 10 dollars. A fair bit better than the 200 my brother paid for his Solingen.

The wooden traveling case was 4. What can you tell me about this brand, age and what of the condition?
