Pig bristles brush. The guy used it after the cream polish was applied. It's kinda tough and springy, and are supposed to force the cream polish into the pores, while removing the excess.
Goat hair brushes are much softer than horsehair. He used the brush (with a lil water on it) for the final buffing. It really seemed to eliminate the streaks/swirls left by hand polishing, but I'm sure it needs some practice. Colonil sells one, and are available through ebay? not sure. I think a lambswool mitten does an equally good job.
BAL WORKS, another fine shoe repair shop in Tokyo, uses similar (but not the same) Edoya brushes as Brift H, but they don't include bristle brushes in their regimen.
I've also seen old school shoe shiners who only use pig bristle brushes and some rags to get some serious shine.
Yeah, one horsehair brush (and maybe some rags for polishing) should be adequate for maintaining shoes.
Personally, I only use a brush (horsehair) for dusting, and use a cloth/rag for the rest (same rag for polishing and buffing). Takes 5 minutes or so. I'm getting too lazy to do a high shine (I rarely use a wax polish), so that's all I really need.
still on topic, what's the use for suede brush? like one that edoya sells
