Any experience with Petrocore Polymer sheath material?

Thank you my friend.

I just ordered two linear feet of this stuff from FortyTwoBlades . I want to make a simple sheath for a SYKCO blade. I was thinking a fold-over style, but with the folded part where the edge would be since this stuff is so tough. Reason being I think it would be difficult and very time consuming to build up a welt to protect the edge from the chicago screws and/or eyelets I would be using to secure the open side.

If there is a better method, I'm open to suggestions.

I recommend a weltless build using garment-style compression rivets. Use double-cap anywhere there'll be a rivet where both sides are visible, and a single-cap where one side is on the interior of the sheath, such as in the case of belt loops. Something like a 6mm rivet spaced 1" apart and firmly set will give you a very durable protection of the edge. The pinch caused by the rivets prevents the edge itself from contacting at all in most cases, but will contact in-line with the material itself in cases where it does. A fold-over can work, but I find it easiest to get best results with a sandwich-style arrangement since if you face the bias of the curved faces where they came off the roll towards one another you naturally end up with some very good pressure against the blade for a firm hold. If looking to cover part of the handle as well as the blade, making both edges of the blade portion riveted with the handle portion folded you can combine the methods.

Thank you for the detailed response. I'll follow your advice.

Happy to help! It has a lot of similarities to other sheath materials, but has a lot of eccentricities of its own, so it's very interesting stuff to work with! One thing I plan on experimenting more with is hot-air welding and drape-molding.
