There are a lot of options when it comes to buying DE blades and these blades sit down toward the bottom.
Sure, they might work for your face, but I would say it is pretty unlikely. I have a face that is pretty forgiving with blades and there are probably 15 or so brands that I take no issue with. Derby is not one of these brands. Additionally, they generally carry low reviews. Nonetheless, I recommend all newbies get a sample pack and figure out what blades work the best for them, and a lot of these packs will include Derby's. Compare against other blades and I believe you'll be able to tell why these blades aren't for most.
