Hi Kerne,
One of the best bargains I have found in Russia are sheath knifes made by Pirat. You can find them in almost any fishing/hunting/hardware shop and they are as cheap as chips (about a tenner) they make normal plain looking knifes and awful looking things that a chav pirate would be happy with, but the steel is great and holds a good edge. Avoid the folding and lock knifes, hinges and pins seem to be a problem for the ruskies.
Winter clothes, you can find them everywhere, in all manner of different camouflage patents but they wont all be waterproof. Its not needed when its minus 25!
All the best
Danny
