Howzit guys...... about 4-5 months ago i started to edc a scrapyard regulator and it quickly became my blade of choice for concealed carry. I have been drilling the regulator to no end.....this knife is massive and is very difficult to access but after a few thousand repetitions it became very fast. I posted this on facebook and it went viral so i decided to put this on youtube and give you guys the link.
