Actually it's not the links I need, it's a special pin.....probably the wrong forum--but my son's halflink chain--a 'Shadow Conspiracy', love BMX names...--seems to require a master pin to reassemble every time. Question is it totally necessary? (since the extra one is long gone, and we can't remember what it looked like) I'm guessing that it's much longer than the regular pins, and tapered in order to be easily pushed through to hold the chain together and the pin straight while using the tool? Then the extra breaks off? Am I making any sense?
