So, you want to make a sheath? Maybe you have a nice old knife lying around that doesn't have one, or has a crappy one. Maybe that knife is store-bought or maybe you made it yourself, maybe it's a hunting knife, a fishing knife, a fighting knife, or a kitchen knife; in any case, you can make a good sheath for it.
So, if you're intrigued, or if you have nothing better to do, read on.
Step 1: Designing the sheath
As you can see from the second picture, the structural design of my sheath is pretty simple. It has a pouch and a belt loop, somewhat contoured to the first half of the grip. Don't think that something simple like this is the only option--there are thousands of other variations you can use, from the practical to the totally outlandish. I favor practical designs , but that's just me.
