I carry one of these every day in my left back pocket along with my handkerchief It takes up very little room and I have been carryiong one of these for around 8 years or so. It is my main sharpening tool as I only use my stones at home when the edge is really damaged or needs to be reshaped. I wear out about one a year and I believe i found them at Lowe's. Mine is carried in a leather pouch that in my opoinion is much better then the nylon one that ocmes with it (The leather puch was how they came when i first started buying these) The first ones were made by EZE-LAP now i use the smith's as they are what i have been able to find
