Merkur Mustache and Brow Razor

The profile of this razor allows trimming and shaping on tight and uneven surfaces. I previously had the same Merkur razor and it provided many years of service. Eventually the threaded head broke off the base. I was unable to find an equivalent replacement so decided to purchase another Merkur. Negatives include the initial cost ($30) and cost of razor replacements ($11 per pack of 10). Some reviewers on another site also indicated the blades are not sharp enough or tend to dig. I agree to some extent, but 2 or 3 repeated strokes will get unwanted mustache hairs removed. It also helps to soften bristles with shaving cream. Bottom line: the design of this razor is unique and provides the best option I have found for trimming and maintaining a mustache.
