took a quick & nasty photo of my balisongs,
Top:marked: Frosts Cutlery - Surgical Steel - Japan
2nd: Hand Made Phillipines 11-521
3rd: (Butterfly logo), Pacific Cutlery - Japan.
Bottom: (unmarked) Rostfrei
the bottom two are amoungst the bland 'tactical' blade shapes that could have come from anywhere. the top two are more 'ethnic', with the filipino one being the most traditional.
(my favourite is actually the bottom unmarked stiletto bladed one
)
