Shofar

I cut – and toot – my own horn. Be careful, though – most deer in USA had covid.

There is no such thing as an ashkenazi or sefardishe shofar.
Shofars are manufactured from the horns of several animals. One of the more popular companies is run by the Bar Sheshet family, but there are lots of manufacturers. The shofars you see in Judaica stores are typically imported for sale.
Ashkenazim prefer using a curved rams horn. Most have on the market we’re partially straightened during manufacturing and are just curved at the large end. Some sefardim (and some ashkenazim) have a preference for a fully curved rams horn that was not straightened at all. They are relatively rare to come across and more difficult to blow. Some sefardim are accustomed to use the horn of a kudu, but there is nothing that makes the shofar sefardi or ashkenazi.

Google Bar Sheshet Ribak shofars. I’m not certain, but I think they might sell direct to consumer as well.
The shofars in Judaica stores around me in NY are mostly importing from Israel. If you do buy from a manufacturer, just beware that there are a lot of Christians who produce shofars, some of which are beautiful, but they cannot be used for tekias shofar on Rosh Hashana.

RW, If you go to the store and research the shofars, I am not sure you can then go to the manufacturer and buy direct. This is not why the store put them out there.
