I have been curious about str8s for a while. I thought this SRB might be a cheap and good way to check out str8 razor shaving. I payed $12 for it, so my expectations was not high. I am impressed with what I got, it's cheaply but well made. The scissor like way it holds the blade is very easy to use and works very well. The blade lines up perfectly with the rest of the razor. I would think that the simple but elegant mechanism will work very well over time also.
I got 5 Shark halfblades with the razor, they are very sharp and easily passes the hanging hair test. I have been very careful so far, and have not cut myself.
I don't know if I'll continue to use it much though, because it takes much longer time to shave, I have to be extremely consentrated to not cut myself and the shave is in fact no better than what my safetyrazor does. However it is very good for trimming sideburns etc., I would have loved to have this razor back when I had a goatee. The precision that is possible with this razor is amazing.
I have no problem recommending this razor to people that is interested in str8 razor shaving or as a travelrazor for a str8 shaver. I think this razor will feel much more like a proper str8 than a Dovo Shavette. The Shark blades also receive my warmest recommendation.
I use: Merkur Futur, Vertical Derbys, Simpson Colonel X2LBB brush and L'Occitane Cade
