You have a belt? Before I got my leather strop all I had was a belt and a horse tack "Latigo". I sit and step on oned end of the belt with my right foot, bring the belt over my knee/thigh and hold the other end of the belt in my left hand, making the belt tight. I stropped that way for years on knives. For touching up I don't see why that wouldn't work in a pinch.
