Never had such an exotic tool nor even been offered to borrow one to see how beautifull the wire locking can be done.
Yesterday was my very first go(solo too) and it worked a treat.
For a good looking finish to a locking wire job it has to be worth the samll outlay, plus they cut the wire and roll back the end to a 'U' shap without needing any regualr side cutters or snipe nose pliers to hand.
What wasn't at all clear from the packaging was whether it was actually & truly British made or simply a rep-packagen import ??
What an excellent tool, I can't believe I've not come across them before! Really impressed with them, small very good grip on wire good solid locking system and will create a nice neat tight twist using the rear handle!
