mmmmm they our nice Ive had a couple that were shortened & reground by the Japanese in ww2 for machete use & prison guard use.
The Best machete ever by quality probably!
Never had the full length one.
These were as Dajak says Definatly first issued in 1898 according to Netherlands Army Museum curater in Delft who wrote the book about the 140 variations they have in thier collection.
