Loke ;
You can purchase a cheapo straight razor
here but I would not recommend it, a decent quality straight razor will set you back at least $200, anything cheaper will not give you the shave you are looking for and it will cause skin irritation.
I bought mine back in the late seventies, back then it cost me $150, it is the top of the line, razor,strap (for sharpening),brush (real camel hair) and case.
My razor was made from surgical stainless steel, after all these years it still looks and performs like new,one word of caution, it takes some practice to learn how to properly sharpen and use these types of blades and never and I mean
never rush when shaving, you can seriously cut yourself and cause a major wound, but, no other blade on the market can even come close to the shave you get with one of these.
