My mum has apparently been looking for replacement hob scraper blades for quite some time, making do with just scrubbing the hell out it

Been looking in all the shops, no luck

She tells me about it and I of course have no idea where you'd find "hob scraper blades"

I take a look and it turns out they're literally just standard razor blades with "hob scraper blade" written on it

She now has plenty after I raided my shaving kit
