If you do a Buck forum search on knife carry you will find a batch of threads showing all sorts of sheaths and hangers for folders and straight knives, commercial and homemade. I have shown this in some of those threads. But, for any new people I will do it one more time. You sew the lining of your front pocket together to form a knife size slot. It will go in an ride near your side seam. If it is a slot to hold both larger and smaller knives, you will have to get good at sliding the small knife out of the slot by going on the outside of your pant leg using your fingertips and it will drop into the regular bottom of your pocket so you can get it. Be careful about sewing too high, making the slot too deep. With the popularity of paracord knots you could store knife in the slot and pull it out with the cord.
