Hi,
I've seen a couple of claimed wwii gunto's up for auction in the last couple of months in the UK, but to my untrained eye, the Kabuto-gane ( hope this is the correct term!) and the odd flattened top loops seemed off - I've attached two different examples. I only saw off as I couldn't see anything like this on any site showing lots of examples of wwii swords.
Quite enjoy reading about the more common fakes so would be interested to know if this is a common sign, or alternatively if it could be legitimate.
I didn't buy either so no urgency, purely curious!
