A few facts I learned from the tour and talking to employees:
-ALL assembly of tools/knives happens in the Portland plant. I saw it happening, so no more worries about foreign assembly! (I have noticed that some accessories are made overseas.)
-Much of the steel they use comes from Michigan
-The plier head pieces are made in Mexico. When LM started with the vender, they were located state-side (Indiana?). When they moved their plant to Mexico, LM decided to stay with the original vender rather than find a new one.
-Much of the stamping/finishing/etc. happens at the plant. They also use a lot of local (Portland area) venders. My father-in-law knows one such vender, so its easy to believe.
