What size edger for 9-10, 11-12 oz leather?

I mostly make items using the above mentioned thicknesses. I’m considering getting a more expensive edger than I currently own and want to get one for these sizes right now and maybe add others later on. Thanks

There are very little standards between makers on size numbering in the last 50 years. Best bet is to ask the maker for a recommendation if you can. If you can’t then ask on forums about a particular maker’s sizing from people that use that makers tools.

Thanks again.
