I have a Park cable housing cutter. While I don't know the quality of the metal they used (though it feels heavy), I feel there's much room for improvement in the design. The cutting action is like a pair of cheap scissors.

The other tools that I have (crank/cassette/bb/ext bearing cup/chain tool) are a mix of Pedros and Spin Doctor. I haven't found any quality issues with those; nor their hardness marking/cutting into my bike components.
