Kai S-Knife blade protector, 17,0x4,8 cm, SK-S

I bought this so I could take my Kai Wakatake petit knife on camping trips, but it's quite disappointing. The knife slides around inside the case and pops out with even just minor jostling. It could work okay in a kitchen drawer, but I definitely wouldn't feel comfortable throwing it in a bag for travel without wrapping the the knife and case together in a towel. That's not something I'd expect to need to do for a product costing 18 euro. The duct tape and cardboard contraption I jury-rigged together is certainly uglier, but works far better.
