thin little blades dont get much love around here, where the catchcry is "8/8 or bust!", but they can be awesome shavers, one of my favourites is a 4/8 invicta.
A little small for me, but those MK's are great shavers. The difference between a 4/8 and 5/8 is huge for me, though strangely the difference between a 5/8 and 6/8 is less noticeable.
Nice score
Swedish steel is quickly becoming one of my favourites. I find they take a little more work on the hones to dial them in, but once they are there, they are smooth shavers.
