Seems to be more of a situational tool. I wanted to transport him on a recumbent trike, because he has more options. but i quickly learned that it is best to use a 15mm axle wrench. This multi-function wrench from ANVIRTUE works best when there are no obstructions, in open areas, or where the nut or bolt doesn't move much. It was very troublesome to use the rear axle on the clutch side than the other side. As I pushed down to get the handle, I realized I wanted to push down. So I would have to hold or pull with one hand and spin with the other. It still worked, but not as quickly as an open-end wrench. So this is going into the general toolbox as there will be times when this will save the day. The smaller end was also used to make a leather case for a 360 pocket camera. It took about a week to run this key up, down and around in the leather case. It has thus become more than just a universal key. Some multi-tools with slots for different nuts or bolts can only be used in one direction. So either tighten or loosen. This multifunctional universal two-way key does not have such problems. The key works in every direction. also a beefy 7.95 mm thick! It should be able to apply some torque with those double sided (smooth) teeth. Recommended, but it's a situational tool.
