AUTO SUPPLY CHANNEL LOCK tiny pliers / 1.5 oz
THese are steel, and the best and most stable. Expensive but last for ever. Might have multi use applications if there is a repair, like pushing a needle thru shoe leather.
TRANGIA pot grabbers / 0.7 oz
THe lightest, but VERY flimsy. Only for very small pots! Be careful! THese come with the Trangia cook set.
MSR min-grabbers / 1.1 oz
These bend over time, and become useless. Aluminum. THese come with any MSR titanium pot. Also available after-market.
MSR standard pot grabber / 1.5 oz
Tried and true design. These come with any MSR aluminum cook-set pot. Same weight as Auto channel lock, but much less versatile. Aluminum.
The above is a list of store bought pot grabbers. Alcohol has burned my hands more than once, and I've seen melted gloves and windshirts. I like a sturdy way to hold a pot of (potentially dangerous) boiling water.
