Saut Ouvert Vintage French automatic knife

Nice old French Saut Ouvert switchblade knife. The knife measures 24cm open (9.5 inches) with steel liners. The flat grind swedge blade appears to be full and shiny with original blade finish and lots of light scratches from light use and is marked SAUT OUVERT along the spine. The black synthetic scales are in good condition with no shrinkage, or cracks. but they do show light scratches and scuffs from handling. The knife works well with the blade tip deep in the well, strong snap and nice lockup open. The sliding safety works well. Nice old French switchblade.
