In very good condition, a rare WW2 British RAF / SOE Survival Folding Clasp Knife
Most likely SEO (Special Operations Executive) as no markings.
The 4 3/4 inch (folded) / 12 inch (unfolded) knife is in very good condition, some wear scrapes, the spring action still good and strong.
These are so rare, especially the SOE knives. But we got lucky, so you can have this one for £1000. Please quote item reference AG14. Full sized images available upon request. Tube 1339-50×8 (0.382).
