I was recently traveling and realized I forgot my strop. I was going to hand strop when I had the idea to use my forearm instead. I thought the forearm is smoother then my hand and I can do longer laps. I was amazed how good the results were. I also used the Murray Carter technique of taking newspaper on the table surface which also works very well. When home I use my Mastro Livi loom strop but if I am not going to be away for more then a week, my arm and newspaper work just fine.
