What materials have been used for handles?

Is that over a fiber-glass reinforced nylon(frn) base?

Also is it affected by petroleum based products ,like gasoline etc...?

nope, watch out for squirrel though, they like res-c.

not me but a member here.

So it is a solid material bonded to the tang?
