I was at 7-Mile Market, the largest kosher market in Baltomore today, and they had some kitchen tools hanging from a display, an onion splitter, a strawberry corer, and an ………OYSTER KNIFE????

I know of one use for an oyster knife, and that is for opening oyster.

It’s basically a paring knife with a heavy spine and a handle suited to prying up shellfish.

Shellfish are (of course) not kosher, so I am unsure as to who would be inclined to buy this knife at 7-Mile Market.
