The Feather SR stands for Super Razor, the newest addition from the Feather Barber products stable. On their website it says only the weight of the razor is enough to shave beard, so at a fairly light 51 grams it must be very agile and well balanced, and I would expect a very light and manouverable shave with very sharp blades, so watch out, it may bite you if you are too casual about using it! For your shave prep you should be zoning in to the shave(game)-play style of Cheslin Klobe (1:40 mark in the video if you are in a rush) NOT that off Eben Etzebeth!
If a Straight Razor is something that appeals to the real man within you, but the stropping and blade maintenance is not for you, then make this Japanese instument yours. Popular by the name of a shavette, this is considered to be a very good alternative 'straight razor' as it requires a very light touch, is super sharp and has very little maintainance, blades are available under the consumables section of our website.
This is a high end product with a superb blasted stainless steel finish that the Japanese are well known for. What we love about this razor is the fact that it was designed to aid or even eliminate the stretching of your skin when shaving, the rounded tip that can seen where the blade protudes the body does the task of perfectly lining up your skin and stubble for the trailing edge. I for one don't stretch my skin at all when using a Feather shavette, and I certainly don't have tight skin, they shave very smooth and effortless, and are well worth the investment.
