Our History

Sowa Tool comes from humble beginnings.  It all started with our founder Gerhard Sr. immigrating to Canada from Germany with the hope to start a new life here.  He started his career purchasing expensive tools from overseas to sell to end users here in Canada.  His son Gerhard Jr. later joined the company and helped usher in a new era.  After a trip to Asia, Gerhard Jr. realized he could produce his own brands, avoiding the middleman.  This helped start the Sowa Tools we know today.
