the knife is just a small liner lock made by stanley.i just really liked the look of it.as for the brown leather sheath,i made it from one piece of 4mm thick leather.its fastened by strips of leather cut 2mm thick at the back and tied in a figure of 8 knot.i put a drop of glue into the centre of the knot so it wont open.the strip at the front is slightly thicker for constant opening and closing.they will accomadate any 4 inch tool,leatherman or otherwise.ive been using my own sheath since last sep. and no problems.theyre real leather and actually get better with age.i just got tired of replacing sheaths for my tools as they are made from bonded leather which really shouldnt be called leather atall.the only sheaths ive come across that are really good quality are the ones that SOG produce.i have a few of them and i cant fault them.
