Nice Burma Knife Chui, certainly a lot easier to open! :thumbup: Having seen how dull they usually come, I was surprised the first time I sharpened one up, the steel was actually pretty good. I see an awful lot of these knives with broken back springs though. The maker is interesting, is there a tang stamp or just the stamp on the scale? There have been several Sheffield J. Halls, but all in the 19th century. I have an old Surgeon's folding knife made by one of the 'J.Halls's.
