I used a Lufkin 6ft folder for 25 years in my job. Now retired, I have been checking out some other offerings. I have a WIHA maxi-flex 2 meter rule, with inch in one side and metric on the other. I like that design because you can read either edge of the rule (whichever side you're using), but I would not get the black one again. The yellow one is much easier to read. I also have a Stabila 2 meter inch/metric. It is white, which is very easy to read, but they have the inch and metric on the same side, inch at the top, metric at the bottom. I like the WIHA design better.
