Thanks Ricky and Mike;
And Mike, as to the belt loop, I was going to add that to this how to but haven't
gotten time to take some work in progress pictures yet, in the mean time here
are some shots of a 110 sheath I made a while back;
Basically one piece of leather, wrapped snugly around the knife for good retention
and then the belt loop is folded down tightly against the back and stitched along
the bottom, this allows you to tilt or raise the sheath when you go to sit down or
draw the knife.
I form, dry, dye, emboss, glue, make the holes for the stitching, stitch down the side
until I reach the corner, then I pull the thread BACK through the top so now both threads
are on the same side
Then I glue the belt loop down agains the back of the sheath, nice and snug so there isn't
too much play, this will keep the knife closer to you.
Once it's glued in place, I use the make shift awl and hammer through the holes to get
through this extra layer of leather.
I use the awl to enlarge the first hole so I can get the one piece of thread back through
to the other side.
And also enlarge the two next to the last holes so I can back stitch two places to lock
down the thread and continue sewing around the end.
Good luck on your project, 5/6 should be ok, 6/7 would be my preferred weight for this style sheath.
