@staticsafe yeah, it feels like a zombie-killing tool!

Note that they have an 800 model (https://www.amazon.com/s/ref=nb_sb_noss_2?url=search-alias%3Daps&field-keywords=rotring+800), but after reading a few reviews, I opted for the 600 rather than the 800. The bummer is the 600 doesn't retract, but the reviews on the 800 are weirdly very mixed about its construction.
