When I started a few months ago, I kept my Victorinox knives in a converted artist's paint box with my other EDC gear, like flash lights, binoculars, hip flask, Zippo, Moleskine note pad and the like. Just two Vics back then!
All this really does go in...

to this case...

But it's now full and the collection is growing...

So I strengthened another wooden case with aluminium extrusion and plate and lined it with foam and vinyl...

And I can get a few more in...

But there are 4 more Wengers coming in a couple of days, so gotta keep looking for a solution!
