After reading an article about special forces and SOG (Studies and Observations Group) knives https://en.wikipedia.org/wiki/SOG_Knife , I decided to make my own leather sheath with a locking strap similar to the SOG sheath.
Create your design on paper and then test for fit.
Step 1: Test Your Paper Model
Test fit the paper, once happy trace to your leather.
Step 2: Tweak It
There will be minor tweaks to fit your knife, here I'm removing a small piece of leather so it fits snugly around the handle.
Step 3: Stitch It
To stitch it, I decide to use picture hanging wire I bought from the dollar store.
The holes I drilled them with a small drill bit at 1/2 inch apart.
Easily threaded the wire using the saddle stitch.
Step 4: Add a Lock to Your Strap
This will come in handy when I go mountain biking so I will not lose my knife.
To secure the strap, I used a piece of electrical copper wire and attached it to the leather and hook the bottom of the sheath.
Step 5: Secure the Bottom
I also made a securing point at the bottom, I drilled a small hole at the bottom and threaded wire through it.
Step 6: Always Improve You Design

To upgrade my design, I decided to add a snap. I bought the snap kit which included the tool for about $5.00 with 50 snaps. A good deal.
Step 7: Final Product
The knife mounted to my bike. I used tie wraps at the top and the wire I threaded at the bottom of the sheath is wrapped around the fork. I will probably dye it black so it blends better.
