I used to use a Weck to shave the tattoo area on customers before the germaphobes demanded twin blade disposables. At that time the only blades available in the local beauty supply were the Personna. I tried shaving my face with one and it was no go for me. AFAIC the Personna blades weren't even very good in shaving an arm or a leg on a customer.

The vintage Weck blades were much better when I could score some NOS on the bay. Referring to shaving the tattoo area, not my face. The Weck was pretty well made, but the frame is plated and will rust if you're not careful. A novelty but not something I would want to have to use as a personal shaver.
