I have a Revolution cane. It has slip on tips. You have to buy the tips specific to Revolution canes. The Ambutech slip on tips will not work with Revolution canes.

On Revolution canes, the tip is a slip on only. The cane’s elastic cord is held in place by a metal washer and strategically placed knots.

To remove the tip, you need quite a bit of pressure. I have the most luck with a vice or pliers. If you don’t have either, you can use a door frame. Caution: you can damage the door and frame this way. Open the door all the way. Slide the cane tip between the door and the door frame on the hinge side of the door. Close the door slowly until you feel it contact your cane. Open the door the slightest bit more so that the cane slides freely between the door and the frame, but the cane tip gets trapped. Now, use some force to pull the cane back toward you. This should start to dislodge the cane tip. Keep going until the tip pops off and your cane comes free of the door.

Hi! I’m not sure if they’re the same as AmbuTech? If so there’s two ways of the tips being secured - push on/screw top, or hook. I think the hook is the most common, and for that you literally pull the tip and some of the elastic out, and, at least on the AmbuTech Cane, there is a flat piece of plastic which then stops the elastic going back in. There’s a loop of elastic now outside of your cane, so you can unhook the top and hook your new one on. Then feel along until you find the piece of plastic, pull it out a bit further and rotate it 90 degrees so it goes back inside the cane, and the elastic retracts the top back in!
