This is a great handle design for use and throwing both I think due to it's flat spine. I have made several sort of like this out of that plastic outside deck material. From time to time I find a piece in the cull rack of the local Home Depot and pick it up for about $2. That much will make about 10 pair of waterproof and almost indestructible grips that have enough grain for a good grip and a semi soft/warm feel. They have several colors but I only seem to find the gray. Anyway, it looks great with a black blade or parkerized finish. The grips on my Becker-9 are of this material and cost about 30 cents and two hours spare time labor.
A quick added note about shoe goo. (by the way I don't work for them) I've mentioned it several times before and have found it to be an incredible product. And yes, it will re-bond shoes when the heels or soles come off. I've even used it to put a layer of soft leather on my wife's shoe soles to keep down noise while she is walking onstage. But what I like about it is that when smeared on the tang it dampens the noise and vibration of thrower handles and is a good enough bond to keep screws in their holes from vibrating out. It seals and prevents movement in a cord wrap and is watertight. But when you want it gone, it will pull off with force and leave both glued surfaces untouched like it was never there! I do a good bit of restoration on antique furniture and use it all the time. Think in terms of epoxy that can be removed without damage to the piece. You can find it almost anywhere and it is cheap.
