I love the 4/8s in my collection. They are nimble and shave just as well as my 6/8s. I use a paddle strop and find it helps when sharpening a smaller razor.

Among my favorite 4/8s:
Strega (Esklstuna Sweden)
Filarmonica Inox
Heljestrand MK24
Le Grelot P-Hospital

These four razors are all top quality shavers!

Happy Shaving!
