I just buy BARBER'S PET Straight Razor Simmons Hardware

I notice, the blade looks a little slanting, and this is explanation from seller:

 "....The blade has been honed with a concave shape, probably on a rounded stone. The good news is that it looks like the razor has been in use recently and has a pretty sharp edge. It will only need a little finish honing to have it shave-ready...."

Is it possible to get a flat blade unlike this one?
