I very much like this ruler: https://www.amazon.com/Westcott-Stainless-Office-6-Inch-10414/dp/B0015ZY25I/ref=sr_1_6?dchild=1&keywords=6+inch+ruler&qid=1603155304&sr=8-6

Have had it for 5 years now and use it daily. I'll probably replace it with the same one eventually but don't anticipate needing to do that for a while!

Only complaints:

• it gets flagged surprisingly often at airport security -- I guess it looks like a knife to them
• if you're using a fine-tip marker with it and push too hard against it, it will 'cut' into the marker a bit over time
• cork on the bottom has now begun to slightly chip at the edges
