I know this may sound ignorant but my girlfriend is afraid that I will cut my throat and bleed to death. This is because I am currently using a five blade cartridge and walk away with razor burn and a little blood from every shave. I think this is because the blades do not stay sharp and I feel like I'm applying more pressure. What is the real threat here? I understand that when using a straight you apply almost zero pressure. Any thoughts are welcome. Thanks
