Pocket Opener Made in China
Around USD 15 for this China Made pocket opener, the original Bergeon opener that is very similar (not really a surprise) costs THB 2'100 in the watch shop in Bangkok, around USD 50!

China Made Pocket Opener, always in my pocket now,
together with a couple of
other items: - an
A&F case opener knife (like this non-sharp blade better then on the Bergeon case
opener knife), a paperclip to remove spring bars and link bars and a 10x
jeweler's pocket loupe, non-metal! Thus suitable for air travels. Of course the
case opener knife has to stay at home!
