4-5 gentle strokes on a clean leather hanging strop make a great difference to the apex keenness; knife sharpeners take this from straight razor users, they finish their straight razor sharpening this way, and also do it before each shaving.
Horse full grain leather, and kangaroo tail are regarded best for hanging strops. But it was by SHARPCO advice that I also started using suede when more aggressive edge cleaning is needed. So my hanging strop is now 2-sided: horse leather, and suede. When it wears off or rather gets too many accidental cuts and scratches, I will replace the horse side with kangaroo tail.
SHARPCO I anyway planned to send you the 3rd revised edition of my Knife Deburring book as a gift when it comes from the publisher by the end of February, and can add to the parcel a kangaroo tail, I have a spare one 600 x 50 mm - just wait for a few weeks, mate.
