Input:
I have used a Swing-A-Way Can Opener for the over forty years. It is a reliably good can opener. It has a comfortable grip. The blades on the opener are are still sharp and work perfectly. I also like that It's very easy to keep this can opener clean. I purchased a new Swing-A-Way Can Opener recently because I needed another one for the kit I take on the road. It's made the same way as the older model I've owned for over forty years.and every bit as good. It's was the only can opener I considered buying.
