Leather for custom paddle strops
Greetings,
I am making two paddle strops out of iroko wood and I am looking to source some leather. I've visited a shoemaking business and had a look at their leathers but I couldn't find something in the 3-4 mm thickness range (I've read somewhere that this is the thickness l should be looking for). Additionally, I suspect that most of their leather was treated with chemicals but I may be wrong.
So what are the characteristics I should be looking for in terms of thickness, texture and tanning method?
Thank you in advance for your answers
Elias
