I want to find a distributor for Metwrench tools but the only results
I do get are personal reviews about the product but no dealers for the
product.

Metwrench is a common misspelling of the Metrinch brand (Metr + inch,
because they work for Metric and Inch)

This is only US Dealer listed on the Metrinch website
http://www.metrinch-tools.com/

Metric an Inch Tools LLC
11100 Santa Monica Blvd 560
Los Angeles, California 90024
Phone :(800)637-9274
CS@worldpro.net

Their web address is http://www.mitools.com/

However, there are many places online that sale Metrinch tools

Cool Tool Sets claims to have the largest selection of Metrinch tools
available on the internet.
