I have not been able to find any good brick and mortar sources for Gehring products either. The only place I've found them recently is at HomeGoods stores (spread across the continental U.S.)
They are sold at excellent closeout prices, but they don't carry a regular stock of them.
I have been trying to find Robert Herder Windmill knives myself. (Windmeuhlenmesser) (website at www.windmuehlenmesser.com
I have also emailed the company several times in English with no response. I suppose I need to try German as well, and see if they can provide me with a source- their knives are amazing.
