I received My Weishi 9306 Safety razor with Yingjili blades yesterday in the mail so with my anticipation I prepped up for the shave shaved as normal as with my cartridge blades only to find a lot of bumps on my neck with redness . please be advised that I did not press on the razor, I let the razor Do the work with the proper angle so went wrong ? Was it the blades or my skin not being used to the first shave with the safety razor I have no clue because I am not a SME on this matter !
