Is the Star Shaving laptop strop a good option to begin with? I can see how having a flat surface would make stropping much easier initially. Its also fairly wide at 3 inches.
I'm also considering their 2 inch leather strop, but that seems a bit narrow. I have a vintage Dubl Duck Pearlduck Special No1 (plan on using that once I'm confident I wont slice it up) that is 2 1/2 inches and its a bit difficult to see how stropping on anything narrower than that would be practical.
