Nice features:
FLAT blade, measures around bends
Millimeters AND Inches on the same blade
Erasable notepad for quickie sketches/measurements
Built-in pencil sharpener
Dual blade locks-so it you can stop the blade with your thumb or index finger
Resistance retraction setting. ie you can reduce or increase the speed the blade retracts, by positioning the thumb-lever
1" wide blade, yet compact housing
4 rivet end-tab
And, each tick mark is labeled (red small numbers for 16ths, and fractions shown) so you don't have to count-up the 16ths to figure out your measurement, as well as noting a 2 (for example) in red, so at 14" you instantly see that 14" is 1' 2".
