This large double sided strop features 3 mm vegetable tanned leather on both sides of a hardwood backing.
One side has the flesh side out and the other side has the top grain out enabling you to have two different finishing edges for a razor sharp knife finish.
The strop is 90mm wide x 300mm long on a 20mm hardwood backing.
Typically a buffing or rubbing compound would be worked into the flesh (grainy) side of the leather where the majority of the stropping would occur, followed by a quick once or twice on the top grain side (no compound)
Stropping compound can be bought from Amazon for about $6 dollars, the brand I like is “Sharpal” and it will last for ages. Another alternative is Autosol which can be bought from many store including super cheap auto etc.
