The Wicked by Powerslide Hardcore Tool, 4mm Hex & Torx T-25
The tool is made out of metal so is strong enough to be suitable for both pulling out bearings (if you have 8mm bearing spacers like most skates) or pushing out bearings (if you have 6mm spacers like K2 and Roces skates).
The Hardcore Tool is not only robust and of the highest quality, but thanks to the exchangeable and removable blades it is also super compact and fits in your pocket.
