Starter dewar recomendations

[Noel Laflamme]

So I am thinking of getting a dewar so I can cryo the AEB-L blades I make, and possible expand the alloys I use, but without spending a small fortune on one, I only really see them with a 1.97in neck, which would work for some, but not all of my knives, especialy the chefs knives.
Is there any places I could find a reasonably priced one with a wider neck or should I just consider putting the wider blades in a cooler and pouring it over them?

Thanks for any input!

You can get a Dewar flask for wider blades. It is a tall insulated cylinder that you pour the LN into and do the cryo. Pour the LN back into the main Dewar after you are done.
