Let's face it, any razor can cut you if you are careless. Most of us have honed our skills and can enjoy a nick/irritation-free shave. However, there is probably one razor (DE/SE/Straight) in your den, that DEMANDS a flawless technique, lest it bite you in the...face . Mine is the Mühle R41 (2013). If there was ever a razor that is just waiting for an opportunity to strike, it's this one. You may ask why I keep it in my den? The answer is that it keeps me honest. What's your most unforgiving razor and do you do anything special to prepare for its usage?
