A collection of PVC sheaths from reader Ugly Rooster - here's his comments:
A little background on the pieces:
Obviously, one of the blades is a Sharpfinger-Old Timer, but the sheath is mine.
You can see a total lack of belt attachment accessories except two holes and cord-
This is totally sufficient and compatible with MOLLE or a similar platform.
Also, placing it under the waist belt makes for a secure ride-high and concealed.
I have worked with Kydex and found that PVC is as easy to work with.
The pictured blades are reciprocating saw blades, once upon a time. So they are free after they are dulled, or they can be had new for about $3 to $7 bucks. They are suited to make fine fixed blade-full tang blades. The one limitation is blade length. They really need to stay at or under 4" if ergonomics, functionality and strength are to be retained. A note about the steel... It is high carbon, heat treated with a Rockwell hardness in the low 50's. Sound familiar? Yep, same steel or similar as to what is in the high dollar blades... If you can find them! The metal is a tad softer due in part to the abuse they are made for.
A note about the steel...
These are already heat treated, so while working them, it is critical to not let them get hot. Dunk them in a cup of water often during the sanding and grinding. Does not apply if you use primitive tools. This cold process will maintain the steels temper. Happy scrounging!
