Ok I am a total newbie at straight shaving but I have been looking at strops all over the place to see whats out there. I used to do the whole mountain man reinacting bit and I have a lot of leather laying in storage. I was wondering if any of these would make good strops? I have elk, deer, buffalo, cow, and even some goat leather. The buffalo and cow are smooth on one side rough on the other just like most strops. The deer, elk, and goat are rough on both sides due to natural removal of the hair with a scraper. The deer elk and goat where brain tanned by me and the only thing used in the tanning was brain. There have been no chemicals of any type used on them. The buffalo and cow however were purchased so I can not attest to what they were tanned with. I would like to see them used for something so as they are not going to waste. Even if they are not strop material maybe some nice leather razor rolls for storage. Any comments are greatly appreciated. Thanks in advance.
