My present Gas supplier can supply me with LN, so thats all good. But i'm not sure what I should be looking for in a Dewar, obviously the neck size is a consideration and long enough to get a big Suji inside. I'm confused about materials, some seem to have a glass inner. Is that bad thing? What type would be best suited for plonking knives in and out? They are very expensive over here.:(
Advice much appreciated.
