Thread: Box strop?

Hi all.
Whilst helping a mate clear out his garage, I came across this.
It was in a cardboard box which is quite worn.
It has 2 colours, 2 sides are black 2 sides are brown, I am guessing that brown is leather and black is linen/canvass.
It appears to be in quite good condition, a few scrapes but no nicks or dents.


So my mate has given me this as he was going to throw it away, looked all over for the razors as he said it was his Grandfathers and he remembers him having a 7 day set in a box. No luck on that front though but he is going to keep looking for me.
Ok so the questions are.
Is it a strop or a hone?
Should I clean it up as it feels quite oily and the black sides leave marks on your fingers and clothes.
How do I clean it?
Looking forward to your responses and ideas.
