I've had a Park CN-4 for about 20 years and for the 6 or so bikes I work on every year it looks like it will last several lifetimes. It does an excellent job on brake and shift inner wires and on shift housing.

It's not wonderful on spiral wound brake housing but I don't think any cable cutter really would be. For these I prefer a set of side cutter pliers where I work one jaw between two adjacent coils and then snip. I then follow up with a flat file to remove any burrs and use a thick needle (a sharpened spoke stub works well too) to reform and round out the inner lining. This takes longer to describe than to do.
