Razor clams aren't the easiest shellfish to find but they are worth the hunt. Luckily, in Scotland their are plenty of good fishmonger's who are happy to supply them. Don't soak razor clams in water as they are salt water shell fish and will die in fresh water quickly. You will also need to vigorously wash razor clams as they are usually full of sand. Be careful when handling them as their shells are very brittle and will break easily.
