Query: Good tongs, but limited dishwasher safety

The OXO Good Grips tongs are excellent tongs with good feel, good grip, and easy one-handed locking and unlocking. Their "good grip" makes them comfortable to use and heat resistant, but are their ultimate failing. If you used these every day, and put them in the dishwasher every day, the grip will break down and start leaving nasty black marks on your hands over time. How long? More than a year, but less than three. I keep hoping OXO will upgrade the quality of their black grips, but sadly no change. So, I gave up. I simply buy these and expect to throw them out in a couple of years, and buy another pair. They are good enough in all other ways that I'm willing to do that. There are a lot of other tong choices, and I've tried a few, but none that perform as well as these. Just don't think they'll last forever if you run them through the dishwasher regularly.
