Klein, Not sure if they're US made (I'd guess so) and they are very nice.

I have a nice "riggers bag" from Duluth trading, US made I think, but they don't offer the same thing any more and what they do have is imported.

Here's a great option, a good friend of ours makes these bags just an hour and a half down the road. I'm sure you can have exactly what you want made if she dosen't have it listed.

I have a few chisel rolls myself and have seen many examples of her work first hand, they're nice and quite sturdy.
