This is a particularly good version of something that can last a long time, however. Having used multiple brands of pruner, this is my favourite because it has replaceable blades and other parts, it's comfortable, easy to maintain, durable (doesn't have plastic handles or cheap lock or something), etc.

We disinfect with lighters. Doubt it harms whatever temper they have and they're easy to keep in your back pocket.

They can gum up (I've trimmed rubber trees with them), but so can anything. Couple drops of oil so that it coats the blade and drips to the hinge, open and close it a couple times, good to go.

Use both and I'm not as big of a fan of the rollers! I dislike the size difference and have also had the "rolling" grip bind in one (awkward) position.
