Outline - A Rapier Scabbard with a Catch
First of all: BE CAREFUL
Supplies
- PVC or similar pipe with ¾ inch internal diameter (may need to be wider depending on your sword) 
- Leather 
- 4 mm 
- 0.8 mm (or fabric of choice) 
- Artificial sinew 
- Preferred dye or paint 
- Leather seal 
- Acrylic seal 
- Metal sheet (18 gauge -20 gauge is probably best) – recommend brass or aluminum 
- Two-part epoxy 
Measurement you’ll need
- Length of the blade from the base to the tip (including cap). 
- Width of the tip at its widest point. 
- Width of the blade at its widest point (if different that the tip). 
Steps
- Cut your pipe about 1 to 1.5 inches shorter than your blade. The cap should extend clearly past the end of the pipe when placed inside. 
- Make a Mitre Cap. - Cut a patch of 4 mm leather with an internal diameter matching the width of the sword’s cap. It should be between 2.5 and 3 inches long. 
- Punch holes along the edges that will be the internal seem. 
- Sew the leather into a tube with an internal diameter to accommodate the rapier cap (wetting the leather can help with the shaping). 
- Cut the end of the cap into a taper, and wet to form a point 
 
- Drill holes along the end of the PVC and the Mitre Cap. 
- Sew the cap into the pipe using artificial sinew (take it in stages). 
- Apply epoxy over the threads and to hold on the cap. 
- Apply raisers (if desired). 
- Cut out cover leather (0.8 mm) and sew over the core (dimensions - core circumference by length). If you use fabric instead, use the same process. 
- Dye the leather (and paint if desired). 
- Seal the leather (first leather seal, then acrylic seal). 
- Make a chape out of sheet metal and epoxy/glue onto the end of the scabbard.
