Home > How To > Bridles Bridles vary from steel wire to pressed sheet metal, to dyneema. The wire bridles are very simple but do have the tenancy to snap at the bend when they get older. Which can be quite a nasty experience for the fingers. This is the one of the reasons that Dyneema bridles are very common. Here's a few commonly used bridles. The first group are articulated. These are different forms of Dyneema bridles. The first is made for screw in rubbers or slings. Then this bridle is used for rap around rubbers, the brass ends are inserted into the rubbers & then tied with a constrictor knot. These Stainless ends are inserted into the rubber ends with the Dyneema tied to the ends with the hole. Dyneema bridles are cheap, easy to make & less painful if they ever do let go. But they don't last on most European shafts & shark fin notches like the Riffe shafts. The notches tend to cut into the Dyneema.
