Why is it that every time I think I've found the perfect SAK for my various needs (58mm Vagabond, 91mm Yeoman, 111mm Carpenter), it turns out to be a retired model?
There is a guy on eBay right now who appears to be liquidating an entire collection. He's got several Yeomen the last time I checked. Prices are high, but if you really want one, he's got a few. If you just search on Victorinox yeoman you'll find them.
Probably because they didn't sell or were too close to another model.
