Noticed on my daily commute from home to work.. bolts seemed to be everywhere.. there are enclosed facilities that can be dismantled using only this tool.. for those who live in the city if im correct there are certain condos who have underground lpg lines.. this tool can be used to turn off the main lpg valve during earthquakes.. also it can also be used to gain access to water pipes.. though a pipe wrench would be a better tool for that. For those who will consider owning a miniwrench for edc.. look for brands that can accomodate up 20 mm (i may be off with my measurements).. stanley and other brands that are within the 5″ length can only accomodate up to 15mm bolts.. my chosenwrench is greenfield.. it can accomodate 20 mm bolts..
