Depending what your budget is, the campagnolo tools are worth the cost! We have the original campagnolo tool set, thousands of pounds, 15+ years old and still going strong, however cyclus are now doing a really good range of tools at a decent price. Possibly look in to that? Soil sampler has posted the best tool for the cost as it has a handle for you to apply a decent amount of pressure with it being an older style bracket which are prone to slipping unless direct pressure is held. The tool operator has mentioned will work more than adequately however as mention, if pressure is put wrongly on the tool it could be prone to slipping and leading to damage of the frame.
