Merkur Double Edge Safety Razor
There are dozens of safety razors out there, but I think this is one of the best all-around models I've seen. The straight cut is great for beginners and experienced shavers alike, and the shorter handle length is classic. The quality in the details of this razor are apparent immediately on inspection.
Hand-tooled in Solingen, Germany by Merkur, manufacturers of fine quality precision shaving instruments since 1906.
