I'm a sucker for cool tools.
I checked out their website, although they are not shy to repeatedly state they are German based I could not find any info pertaining to where they are manufactured.
I have a pliers-wrench sitting on my desk right now. It has "MADE IN GERMANY" right on the casting, and on the handles too.
I think it's safe to say that's where they're actually made.:D
They are very nice, and have caused the retirement of channel lock pliers, a couple crescent wrenches, and smaller pipe wrenches.
Certainly no replacement for a full on wrench or socket set, though.
Amazon.ca seems to have the best price, or they did when I got mine.
Not Knipex, but still interesting, is this hex key set I got recently… Wiha Magic Ring ball end hex keys They were on sale when I bought them, but don't seem to be now. Wiha often has sales though. Usually 30-50% off.
