I came across this product and it is fantastic and inexpensive. It is leather coated with Chromium Oxide glued to a wood block. Notice how smooth and even the chromium oxide is. I have a Jnat, Escher, Name: IMG_0202.jpg Views: 313 Size: 10.6 KB stones from Naniwa, Shapton and a Suehiro 20k but this block really refreshes the razors with just 3-5 laps, then 10-15 laps on a leather modular paddle strop and the blade is really sharp and gives the smoothest most comfortable shave so far. I have tried it on different steel and 6-8 different manufacturers razors and they all came out great. Comes in 2.5" & 3" widths. This is made for knives but at $29.95 for the 2.5" you can't go wrong. Much less then any other similar strop on the market. The chromium oxide is melted on the leather then sanded and smoothed out.
