You can burnish chrome tan with tokonole. I've definitely found doing the edges on chrome tan never comes out quite as well as veg tan though. I know some people use edge kote or paint for chrome tan edges too, but I like the tokonole.
I use Tokonole pretty much on everything. I recently had a chrome tan though that was (for me) impossible to burnish. I tried a wooden slicker and canvas and all it did was fray. Does Tokonole work on all chrome tan for you? I am still quite the beginner so I wouldn’t doubt it’s me.
Edge kote is that similar to Tokonole or more a thicker liquid to coat the edge?
No some leather won't burnish, it's not just you. I'm not a pro at thus stuff either. Like chromexcel you can get a decent burnish on. But when I've used crazy horse and similar leather I just edge koted it instead. So it really depends on the leather.
