These sound like a good idea, strong metal core with a gentle plastic covering until is snaps the very first time it is used. I will stick with the all plastic or all metal.
This set of levels are great to take on any tire job while light enough to be carry in your bike or your pockets. They have been reliable every time I have used them and with the right size and strength to insure you can rely on it without breaking or bending. Highly recommended
I've been biking for a long time, but never thought I'd get this excited over a set of tire levers. Occasionally, I have to deal with tires that just seem a bit undersized for the rim - and I'm sure I'm not the only one. These levers are big and strong, with the right shape, to make easy work of it. Closest I've come to love at first sight in a very long time. Downside - they are relatively big and heavy. BUT they actually work. No brainer for the workbench at home. Remembering my last 30 minute fiasco changing out a tire on a ride that was just too tight - I put these in my seat bag. I'll watch my diet and lose the extra ounces to make up for the extra weight. I'll buy another pair or two or three to keep on my workbench and in my wife's seat bag. One caution - don't lend these to anyone, guaranteed you'll never see them again.
